But probably nothing today is more certain and challenging than change. Agriculture is a dynamic enterprise and it is a perfect example of change in action and of the impact of change. We are creatures of habit, and change makes us uncomfortable. We like to wear familiar clothes and comfortable, well-worn shoes. But change is constantly upon us and those who adapt, survive and prosper; those who don't, fade away. Charles Darwin distinguished himself with his sharp insight into the simple relationships among change, adaptation and survival in the natural world. To survive today, the agricultural industry must continue to adapt rapidly; natural resource, environmental and human resource planners must adapt, and we in the Florida Agricultural Experiment Station (FAES), of the University of Florida, Institute of Food and Agricultural Sciences (IFAS), must adapt in a number of ways. Research programs must adapt to shifting public priorities regarding the quantity and quality of our food and natural resources and to increased competition for production agriculture in the global marketplace. The latter brings a constant need for more efficient plants and animals and, hence, pressure for more research. Newu crops, changes in the importance of existing crops, a constant influx of new living material into the state, especially pestiferous insects and diseases, all strongly influence research direction. There is change also in the funding of research. With constant or declining public dollars, IFAS/FAES relies more heavily on partnerships with producers, industry, non- government organizations and foundations for cooperative projects that address our common goals. IFAS/FAES has been successful in adapting to these changes. Thanks to committed partnerships, our research programs remain productive and efficacious. We will continue to provide solutions to the many challenges facing our agricultural and natural resource industries. This leads to the issue of accountability. IFAS/FAES is accountable to our congressional and state mandates, and consequently, to the taxpayer. We are also accountable to our funding partners. By all measures, IFAS/FAES delivers. With respect to agricultural research, numerous studies have documented a 30-50 percent return on investment per year. This research accounts for the remark- able two-fold productivity increase over the past 30 years and for the leadership position of the U.S. with respect to agriculture. U.S. taxpayers enjoy the highest quality, most inexpensive food in the world. Together with the best producers in the world, research has enabled this record. Today, further research is leading to significant reductions in the impact of agricultural production on the environment. For example, the intense use in Florida of biocontrol agents as pesticide replacements is remarkable and due almost entirely to IFAS/FAES research. But the public expects specifics, and IFASIFAES will be compiling documentation soon to meet the requirements of recent state and federal mandates for accountability. This Annual Report highlights a few examples of the scope and impact of IFASIFAES research programs, a list of faculty by unit, publications, titles of current research projects and a brief financial report. Completed research is reported in scientific journals, bulletins, circulars, books and conference proceedings. Our scientists also participate exten- sively in field days, short courses, conferences and other public informational programs to inform produc- ers and consumers about recent research findings as well as to collect information to help set new research directions. The end of 1995 marks the completion of almost one year of my tenure as Director of IFAS/FAES. I have enjoyed it greatly. The diversity of the industry, the quality of our natural resource base and the commitment and cooperation of the people have impressed me immensely. While we have many challenges, the opportunities are limitless. I look forward to the future. Richard L. Jones Dean for Research and Director, Florida Agricultural Experiment Station Institute of Food and Agricultural Sciences University of Florida 2 Selected Research Accomplishments ANIMAL SCIENCE Secretion of Novel Proteins from the Ovary of the Cow: Potential Impact on Ovulation, Sustaining a Pregnancy and Assuring an Optimal Outcome at Birth of the Calf Situation: The - corpus luteum (CL) of the ovary forms in place of the follicle after release of the egg at the time of - ovulation. This structure is known as one of the fastest growing tissues of the body growing from the size of a pea immediately after ovulation to the size of a strawberry in a matter of seven days. It is one of the biologi- cal clocks of the reproductive cycles that determines the time of ovulation, the receptivity of the cow to mating, the maintenance of Professor Michael Fields examines a pregnancy and the herd of cattle at a UF/IFAS research farm process of birth of facility. the calf. Its effect on these outcomes is primarily through the secretion of the hormone progesterone. It is our position that the CL secretes other factors that are critical to the well being of this gland as well as to a successful outcome to the above parameters. Attempts are underway to isolate and identify those proteins secreted by the CL of the estrous cycle and pregnancy. Once secreted proteins are identified the next step will be to determine the regulatory control of their respective genes and determine the function of the secreted protein by this gland so critical to a successful outcome of reproducing the species. Rationale: The CL is identified with three problem areas of reproduction of the cow. First, a cow with a CL that produces lower levels of progesterone has a reduced chance of a pregnancy that will be sustained. It is estimated that up to 25 percent of the embryos are lost during the first 30 days of pregnancy. A missed breeding of just 21 days (length of an estrous cycle) cost the industry on today's market $25 per cow. Second, precise control of the CL and thus ovulation is required if Timed Artificial Insemination (AI) to breed the entire cow herd on a single day is going to become a reality. AI is such a labor-intensive activity that less than 3 percent of the beef cows are inseminated. Yet this is the fastest and most economical approach to improving the genetics of the cow herd. AI adds $25/cow bred in value to the calf. Third, in some species the CL is absolutely required for birth of the young. In the cow it is not an absolute requirement but without the CL there will not be a normal birth, i.e., there will be retained placenta, calving difficulty requiring assistance and death of a large number of calves. About 6 percent of all calves are born dead or die shortly after birth. The loss of a calf is a loss to the industry of about $300 per calf. These numbers can be extrapolated to a U.S. cow herd that numbers 42.5 million and a Florida cow herd of 1.3 million (Florida Agricultural Statistics 1994). Utilizing the powerful techniques of biotechnology we intend to identify those factors produced by the CL that affect these reproductive events and develop management techniques to improve the reproduc- tive performance of beef cattle. Impact: Eleven different proteins have been characterized as secreted by the CL of the cow across the estrous cycle and pregnancy. Four of these proteins have been identified in the last 12 months through the use of computer analysis of their amino acid sequence (dissertation research of Florence Ndikum-Moffor). Computer analysis has also given us an indication of the function of these proteins. Through the use of molecular biology tools incorporating cDNA probes, the genetic message for these proteins have been identified in the CL along with information on the cell type within the gland producing the proteins. Two ot the proteins are associated with the Low Density Lipopro- tein (LDL) and High Density Lipoprotein (HDL) and are Apolipoproteins E and A-1, respectively. These proteins are associated with cholesterol delivery to the ovary and placenta of pregnancy for progesterone synthesis for sustaining pregnancy. This is the first report of the CL of any species producing and secreting these proteins. Two other proteins are the TIMP-1 and TIMP-2 and are believed involved in the rapid development of the CL, the demise and reorganization of the CL that would allow for ovulation and very importantly we believe it has a critical role to play in setting the stage for a successful outcome at birth of the calf. This is the first report of these proteins being secreted by the CL of the pregnant cow. Understand- ing the secretion and the role these proteins of the CL play also has implication for understanding how the human body functions during the menstrual cycle and pregnancy. Selected Research Accomplishments 3 Collaborators: Funding for this research was through the Florida Dairy Farmers Milk Check-Off Fund and through the Binational Agricultural Development Fund in collabo- ration with Anna-Riitta Fuchs Cornell University, Mordechai Shemesh in Bet Dagan, Israel, and Richard Ivell in Hamburg, Germany. The Interdisciplinary Center for Biotechnology Research at UF have been faithful supporters of this research along with collaboration with Phillip A. Fields at the University of South Alabama. Work is ongoing with Norio Katoh and Shin Oikawa of the National Institute of Animal Health Tsukuba, Japan and here at the UF with Rosalia C.M. Simmen and William C. Buhi. Animal Science Michael J. Fields MICROBIOLOGY & CELL SCIENCE Conversion of Agricultural Residues Into Fuel Ethanol Situation: The technology is not available to convert lignocellulosic agricultural residues such as citrus pulp, stover, stems, hulls, sawdust, pulp and paper sludge, landfilled paper and yard trash, etc., into fuel ethanol. Production of liquid fuel from agricultural and waste materials would reduce U.S. dependence on imported oil, contribute to the solution of environmental problems, reduce the trade imbalance, increase revenues to farmers and provide jobs in a new industry. A " ^^jtK ! Mt4 Note that all liquid fuel used in Florida represents a trade deficit either with other states or nations. Rationale: Although the technology is available for conversion, the challenges remaining are to improve and optimize the individual components and to demonstrate that this technology is cost effective. Research underway at the Department of Microbiology and Cell Science in collaboration with USDA laboratories in Winter Haven, Fla., and Peoria, Ill., is focused on this problem. Our work at UF has concentrated on the genetic engineer- ing of improved organisms to serve at the biocatalyst, and on generic process development. R.J. Bothast and his associates at the USDA in Peoria focus on the conversion of corn fibers and corn residues; Karel Grohmann at the UJSD)A Citrus Laboratory at Winter Haven and his associates are focussing on the conversion of citrus pulp to fuel ethanol as an alternative to animal feed. Impact: Half of the world's annual petroleum production is consumed in the United States, over half of which is used as automotive fuels. Over half of the petroleum used in the U.S. is imported each year, at a cost of equivalent to half of the annual U.S. trade deficit. At least half of this automotive fuel could be replaced by fuel ethanol produced within the U.S. using waste materials and undervalued agricultural residues as feedstocks. Implementation of this technology would increase revenues to farmers, add jobs and decrease our trade imbalance. Collaborators: Active collaborations are continuing with R. J. Bothast and R. B. Hespell, USDA-ARS, National Center for Agricultural Utilization Research. Additional collaborations are continuing with Karel Grohmann, head of the USDA-ARS U. S. Citrus and Subtropical Products Laboratory in Winter Haven. Research at UF is supported by a USDA National Re- search Initiative grant under the direction of Jeff Conrad, cooperative agreements with the USDA NCAUR in Peoria (funds provided by Lamar Harris, USDA program leader for energy), by the U.S. Department of Energy, Basic Energy Sciences, Division of Energy Biosciences (0.

With intense genetic selection and optimized management, milk production of dairy cows has increased. Herd size has also increased and this is most evident in Florida in which mean herd size is 485 cows. To optimize herd performance, it is imperative that lactating dairy cows produce a calf every 13 to 14 months. This is a physiologi- cal and management challenge in high-producing dairy cows in which artificial insemination is practiced. Nation- wide, approximately 50 percent of heats are not detected and this represents missed opportunities to establish a new pregnancy by artificial insemination. Missed heats are not due solely to mismanagement by the dairy producer. Intensity of behavior heat is reduced in high-producing cows whose metabolic hormonal status does not necessarily optimize ovarian follicular development. Proper develop- ment of a follicle is responsible for induction of estrus and producing the hormonal conditions that will allow the initiation and maintenance of pregnancy. These physi- ological and management constraints are further enhanced during the seasonal periods of elevated temperature and humidity in Florida. Improved reproductive performance and management has been deemed as one of the most important components to increase net income on commercial dairies. Rationale: The complexity of improving reproductive performance and management led to the need of integrat- ing the disciplines of reproduction, nutrition, management and veterinary herd health. Thus, support dollars have come from interdisciplinary efforts involving state funding but also extramural funding from the USDA, the Florida dairy industry itself and commercial companies involved with the dairy industry. The management programs that have been implemented involved technology transfer of basic reproductive and nutritional control systems on to their implementation with dairy farms that can directly apply the technology. An ovarian control system has been developed that permits the programmed recruitment of an ovulatory follicle after the injection of a commercially available hormone called GnRH, Gonadotrophin Releasing Hor- mone. On day seven after injection of GnRH, cows are injected with Prostaglandin (PG) 2 (PGF2; Lutalyse) to regress the corpus luteum that permits final maturation of the ovulatory follicle. On day nine, cows are injected again with GnRH that causes the ovulatory follicle to ovulate 30 hours later. All cows are artificially inseminated at 15 1e"r ~LIILE 14i Graduate Research Professor William Thatcher treats one of the hundreds of cows at the UF/IFAS Dairy Research Unit. hours after the injection of PGF2 which is also 15 hours before ovulation. This permits the sperm to develop the capacity to fertilize the egg. This system eliminates the need for heat detection since insemination is implemented at a fixed time. The timing of injections is very conducive to farm management allowing the system to be imple- mented in groups of animals on a weekly basis. Research trials completed on a commercial dairy farm indicate that pregnancy rates are comparable to what is achieved in control cows (receiving GnRH and PGF2 seven days apart, and inseminated at detected heat). The timed Al program gave consistent pregnancy rates from month to month (January to May) and higher levels during the warmer months of April and May compared to the control group. Undoubtedly, these systems offer a distinct advantage over a non-programmed system that would normally be prac- ticed on the farm. These reproductive management systems have been implemented with nutritional targeted programs of fat feeding to stimulate ovarian follicular activity. Impact: Due to reductions in days to first insemination and days to conception, there is a potential savings of approximately $90 per cow. Programmed insemination of cows will also permit a greater number of cows to be inseminated prior to the more difficult heat stress season when embryonic deaths are high. The programmed breeding system also permits a greater opportunity to predict herd production and performance to optimize overall profit of the farm in the future. Since a large amount of the reproductive decisions and tasks are managed at specific times during the week, it should permit a reduction in labor costs. The overall economic impact of the program is being evaluated currently. Collaborators: This research included faculty from the Departments of Dairy and Poultry Sciences (William W. Thatcher, Reproductive Physiologist; Charles R. Staples, Nutritionist), Large Animal Clinical Sciences (Carlos -- - ?eE3~jr~E;3 ~- r w #41 --Ole -A-L Selected Research Accomplishments 5 Risco and Maarten Drost, Veterinarians), Postdoctoral and Ph.D. trainees (Eric Schmitt, Joan Burke, Luzbel de la Sota), Commercial Dairy Farms (Larson's Dairy, Okeechobee; Alliance Dairy, Trenton, and North Florida Holsteins, Trenton). Various funding agencies and commercial sources have contributed to the research for developing this program area: USDA-CSRS-Bard Grant #94-343339, USDA/CSRS Special Grants in Tropical/ Subtropical Agricultural Research, Florida Dairy Check-off Program, Hoechst Roussel Agri-vet, Somerville, N.J. and the Upjohn Co., Kalamazoo, Mich. Dairy and Poultry Sciences William W. Thatcher ENTOMOLOGY AND NEMATOLOGY Behavioral Modification of the Subterranean Termite, Reticulotermis flavipes: Induction of Hypersensitivity to Microbial Control Agents Situation: The subterranean termite, Reticulotermis flavipes, is a major urban insect pest in the temperate and subtropical regions. At present, management of this insect pest requires chemical insecticide applications. To date, attempts to develop alternative controls such as biological control agents have been unsuccessful. In recent years, a new class of insecticidal nitroguanidine compounds have been developed by Bayer Corp. In 1993, our laboratory initiated a collaborative project with Bayer to research the direct and indirect effects of nitroguanidine compounds on insects (including R. flavipes). A Professor Drion Boucias prepares a culture in his laboratory at the UF/IFAS Entomology and Nematology Department. Rationale: In the early 1990s the Bayer research team headed by W. Zeck (Vero Beach facility) discovered that exposure to sublethal dosages of nitroguanidine imidocloprid caused termites to rapidly succumb to various diseases. Our laboratory, specializing in insect pathogens, received support from Bayer to examine the effects of imidocloprid on termite biology. Specific objectives included: (1) confirmation of the synergistic activity induced by imidocloprid; (2) identification of the resistant mechanisms employed by naive termites against invasive pathogens; and (3) definition of how imidocloprid dis- rupted the termites defense against entomopathogens. Impact: Our research determined that certain neurotoxins such as imidocloprid could, at extremely low concentra- tions, modulate insect behavior. The R. flavipes, an insect highly resistant to pathogens, becomes highly susceptible to various microbial agents upon exposure to sublethal concentrations of imidocloprid. These suggest the poten- tial compatibility of a chemical stressor and entomopathogens. Our research also has demonstrated that the termites, unlike many insects, rely upon their social behavior, (grooming, tunnel construction) for protection against disease attack. These behaviors in combination with gut microflora confer a high degree of disease resis- tance upon these social insects. Exposure to low dosages of imidocloprid disrupts these social interactions. The termites, acting independent of the colony, quickly succumb to either introduced or resident diseases. In summary, our research on imidocloprid-termite-pathogen interaction demonstrates that social insects possess a potent behavioral resistance to disease. Successful imple- mentation of the selective microbial control agents can be greatly enhanced by behavior-modifying agents. Lastly, insecticides such as imidocloprid have been clearly shown to dramatically impact insect populations at sublethal concentrations. Collaborators: Bayer Corp., (G.

Boucias FISHERIES AND AQUATIC SCIENCES Use of Bayluscide to Control Nuisance Snails on Ornamental Fish Farms Situation: Snails which live in the mud of ornamental fish ponds serve as intermediate hosts of an important parasite which causes loss of an estimated $3.5 million annually to 6 Selected Research Accomplishments the Florida tropical fish industry. The snails could not be controlled with legal chemicals available to the industry, and once the parasite encysted in fish tissue, it was non-treatable. Bavluscide is a mo1luscide used in the Great Lakes but was not legally approved for use in Florida. Laboratory and Professor Wallis Clark examines a fl orat iespecimen under his microscope at the field studies were UF/IFAS Fisheries and Aquatic Sciences conducted to Department. develop the needed data to obtain EPA approval for use of this compound in Florida's tropical fish industry. Rationale: Research support in the amount of $20,000 was provided by the Florida Department of Agriculture and Consumer Services to investigate the efficacy and safety of Bayluscide (an EPA-labeled molluscicide) for use in Florida's ornamental fish industry. An additional $2,000 was provided by the Florida Tropical Fish Farmers Associa- tion to hire a consultant to assist with the preparation of the packet required for EPA approval of this product in Florida. All field work was done in cooperation with Ekk-Will Waterlife Resources (Gibsonton), which donated personnel, pond space and many man-hours to the project. Estimated in-kind services exceeded $10,000. Impact: Bayluscide was approved for use in Florida's ornamental fish industry in 1994, and imported from Puerto Rico in 1995. Early reports from producers indicate that the product is cost-effective and producers are pleased with the results of its use. Potential economic impact to Florida growers is $3.5 million annually.

Clark Jr. FOOD SCIENCE AND HUMAN NUTRITION Folate Requirements of Pregnant Women Situation: This research is designed to provide more definitive data related to how much of the water-soluble vitamin, folate.J or folic acid, is required bv pregnant women. The most concen- trated food sources i of the vitamin include those that Florida is well- known for, orange Professor Lynn Bailey dispenses a tolic acid supplement for one of her research juice and green subjects at the UF/IFAS Food Science leafy vegetables. and Human Nutrition Department. Folate is required for cells to divide since DNA synthesis utilizes folate- dependent enzymes. Rapidly dividing cells also have a very high requirement for the vitamin since each cell division is folate-dependent. A folate deficiency is associated with megaloblastic anemia, low-birthweight infants, and specific types of birth defects called neural tube defects. Adequate amounts of folate are critical in terms of ensuring normal fetal growth and development. There is currently a great deal of uncertainty regarding the quantity of folate that pregnant women should be advised to consume. This research study is the first controlled metabolic study in pregnant women designed to provide a basis for the Recommended Dietary Allowance (RDA) for folate. The objective of the study is to determine folate require- ments by assessing changes in blood and urine folate levels during a 12-week period of gestation. The most recently published RDA set by the National Academy of Sciences is 400 micrograms per day for the pregnant woman. The previous RDA was 800 micrograms and is the amount present in some prenatal supplements. The study groups include two groups of pregnant women and two groups of non-pregnant controls, all of whom consume either 400 or 800 micrograms of folate per day. Expectant mothers begin the study at week 14 of gestation and continue through week 25. By focusing of the second trimester, it will be possible to assess how much of the vitamin is being stored, Selected Research Accomplishments 7 utilized and excreted during this time of rapid cell growth when the demands for folate may be the highest. Rationale: The experiment requires subjects to come to the metabolic facility for all meals seven days per week for 12 weeks. All fo-o is analyzed in the laboratory and daily intakes of all nutrients are estimated. Folate is provided in a form that has been labeled with the stable isotope deuterium. The experimental protocol is labor intensive and requires an enormous staff and resources to prepare and analyze the controlled metabolic diets, to synthesize the deuterium-labeled folic acid, and to analyze all blood and urine samples. Each subject is paid a stipend ($1,200) to participate in the study. Impact: It is expected that recommendations for folate intake for pregnant women will be revised and that nutritionists and health care providers can recommend either 400 or 800 micrograms per day with a better understanding of how this will impact folate status during pregnancy. It will provide nutritionists with much needed information on how to design diets for pregnant women. For example, if it is determined that the RDA should be revised to 800 micrograms per day instead of 400 micro- grams, dietary recommendations will need to be formulated with this in mind. Since the majority of the population consumes less than the current RDA (400 micrograms), an increase will mean a greater emphasis on folate-dense foods such as orange juice and green leafy vegetables. A decision to increase the RDA to 800 micrograms would significantly impact the following: (1) prenatal folate recommendations to ensure optimal status; (2) establishing standards for nutrition education programs; (3) planning and evaluating adequate diets for pregnant population groups; and (4) marketing food products. The impact of this change may be a significant increase in orange juice consumption in the U.S. because orange juice is one of the most concentrated sources of folate and is the No. 1 contributor of folate to the diet. A revised recommendation that all pregnant women should double their folate intake could have a significant impact on Florida's economy by increasing the sale of orange juice. Efforts to increase consumer awareness of orange juice as a source of folate could be coupled with recommendations to increase intake.

In years past, this fact raised little concern given that non-college bound youth could move into the labor force by securing jobs in the goods-produc- ing sector of the economy. In many respects, these jobs paid decent wages for unskilled or semi-skilled laborers. However, the situation has shifted dramatically over the last two decades. The industrial and occupational distribu- tion of U.S. employment has moved in the direction of favoring better-educated over less-educated workers. Three key forces serving as the underpinnings of this expanded need for more educated workers are the global- ization of our nation's economy, the introduction of new sophisticated computer technologies, and enhancements in the knowledge-intensive, problem-solving capability needed by workers. These changed circumstances have led to major declines in jobs tied to the goods-producing industries of the U.S. a sector which has experienced jobs losses of about 1.3 million in manufacturing alone since 1989. In its place have come a host of new jobs in the service and retail sectors for non-college bound youth, but at wage rates well below those paid by manufacturing-based firms. Such structural shifts have had staggering conse- quences for young workers. In fact, one researcher found that the proportion of 18-year-olds working full-time and making low wages soared from 22.9 percent in 1979 to 43.4 percent in 1990. 4S 4 i -s * .-P,. - U .-. -J'~ / / / t; 1. iJ A Professor Lionel Beaulieu prepares research materials for his reports on youth and education. r? I ~ Iri. 8 Selected Research Accomplishments It is this increasing concern with the plight of young people with no plans to enter college that led the William T. Grant Foundation Commission on Work, Family and Citizenship to label these individuals "the forgotten half." These individuals face serious barriers in realizing a smooth transition from school to work and have few resources which can be tapped to assist them in their entrance into the work force. Rationale: Discussion currently taking place at the national and state level concerns the importance of addressing the human capital resource problems of our nation and state. The intent is to focus attention on the needs that might exist in realizing a labor force that is adequately educated and trained to compete effectively in today's global economy. But, a key issue which has been given less serious treatment has been the fate of non- college-bound high school graduates who have entered the labor force. Who are these non-college bound youth and how have they fared in the local labor market? Given their limited education and undeveloped skills, have they been relegated to jobs situated in the least favored sectors of the economy? And, has their access to better jobs been shaped by factors such as gender, race/ethnicity, or place of residence? These are the set of questions that serve as the central focus of this research. Why is this research important? From the perspective of social science researchers and policy analysts, most non- college bound youth suffer from limited job options, poor wages, less than full-time work, and have few opportunities for advancement once in the labor force. Furthermore, they suggest that these individuals suffer prolonged periods of unemployment, particularly minority youth or those who live in the central cities or rural areas of the country. Unfortunately, these assertions rarely are based on any rigorous analysis and as such, remain untested. The research activities of this unit are designed to give atten- tion to the labor force experiences of non-college bound youth and to provide a scientific foundation for guiding the school-to-work transition policies or programs of federal and state governmental agencies. Impact: Key research findings include: Most non-college- bound youth are raised in a home environment where parental education is low. Furthermore, approximately 45 percent of these youth have four or more family siblings; only 3.1 percent have no siblings at all. From the stand- point of regional location, over 43 percent of non-college- bound youth are residents of the U.S. South. Unlike what some have suggested, non-college-bound youth do not go from one job to the next in the early years after high school, but tend to be employed in only one or t'wo jobs. Approximately nine of every 10 jobs held by non-college- bound youth are characterized as low wage, dead-end jobs which only a few are able to escape even after four years in the labor market. African-Americans appear to suffer greater obstacles in terms of gaining access to better paying jobs over time. Only about 28 percent were able to move into a more favorable job position after two years, a rate that is 50 percent lower than that for Hispanics or whites. Over 43 percent of non-college-bound youth from rural/ farm communities and urban areas wind up employed in the least attractive jobs available, those paying low wages and that offer workers few chances for advancement. These findings can have significant importance in guiding programs and policies associated with human capital development efforts, both nationally and in Florida. Both federal education goals (i.e., Goals 2000) and Florida education goals (i.e., Blueprint 2000) specify as a key objective the preparing of high school graduates for post- secondary employment. This research offers a scientifically sound basis for determining the difficulties that await high school graduates when they enter the labor force. More importantly, it provides a profile of those students who are most likely to be non-college bound and the geographic areas in which they are most likely to reside (i.e., rural areas and urban cities). Such data provides a basis for targeting school-to-work transition policies and programs to areas and population groups that are likely to be in greatest need for these type of interventions. Collaborators: This research is being carried out in collaboration with colleagues associated with the Florida Inter-University Center for Child and Family Studies. This center brings together multi-disciplinary faculty from UF, Florida A&M University, Florida State University, and the University of South Florida in research, education, policy, and service activities to improve the well-being of families and children in Florida and the nation. In addition, the findings associated with this line of research are guiding the work of the Florida Cooperative Extension Service's state major program titled: Preparing Youth for the World Work. This educational program is designed to help youth become more aware of the chang- ing workplace, the skills required for new jobs in the 21st century, and the role of continuing education in relation to the workplace. Members of this major state program are drawn from several IFAS social science departments (i.e., 4-H Youth Development, Home Economics, and Agricultural Education and Communications), from the 1890 Cooperative Extension Service program located at Selected Research Accomplishments 9 Florida A&M University, and from a select number of county extension offices in Florida. Lionel J. Beaulieu 4-H and Other Youth Programs HORTICULTURAL SCIENCES Reducing Bruising During Handling and Packing of Bell Peppers in Florida Situation: Florida is the leading U.S. producer of bell peppers destined for fresh market, with annual farm-gate returns in excess of $170 million. Bell peppers are produced from October through June in all regions of the state. Since bell peppers are botanically a hollow fruit, they are quite sensitive to bruises, and although a small amount is field packed, the majority of these peppers are transported to packinghouses for grading and packing operations. The increased number of handling steps and transfers required for mechanized handling increases the potential for bruising and poor quality upon arrival at receivers. Rationale: A series of projects have been completed related to reduction of bell pepper bruising during commer- cial handling operations. These include: quantification of bruising on typical bell pepper packing lines; identification of sources of bruising during handling and packing; determination of the effects of pulp temperature on sensitivity to bruising; development of a standardized shipping container designed for better handling and cooling. Impact: As a result of these projects, several changes have been implemented by Florida packer/shippers. Many companies have made modifications to packing lines in Associate Professor Steven Sargent tests the color of tomatoes in his research laboratory at the UF/IFAS Horticultural Sciences Department. order to reduce bruising. One packing line manufacturer has added cushioning in key areas of the packing equip- ment which were previously abusive to the product. Several packers have incorporated several concepts of the standardized shipping container to permit more thorough cooling and facilitate the change from manual loading of refrigerated trailers at shipping point to palletization on industry-standard pallets. In the face of increased competi- tion from Mexico and other production areas, buyers should opt for Florida-grown produce as quality and value improve.

Horticultural Sciences Steven A. Sargent Reducing Leaching of Citrus Herbicides With Adjuvants Situation: Groundwater contamination . from agrichemicals is a growing concern in the United States. The problem is particularly severe in Florida where most citrus is grown on perme- able sandy soils with a high annual rainfall . and a high degree of recharge to the groundwater. This ." ' problem is of Professor Megh Singh examines a patch specific signifi- of turfgrass in a greenhouse at the UF/ chance in citrus- IFAS Citrus Research and Education groves where Center in Lake Alfred. multiple applica- tions of pre-emergence herbicides are made at high rates. I Icrbicide leaching not only can cause groundwater contamination but also reduces efficacy of soil-applied herbicides by decreasing available herbicide in upper soil layers where weed roots or seeds are located. Deeply leached herbicides tend to degrade more slowly because of less microbial activity and have greater potential to Selected Research Accomplishments contaminate the environment than herbicides remained in the upper soil layers. Groundwater is a major source of drinking water in Florida. There is a serious need to restrict the downward movement of pesticides in the soil without sacrificing pesticidal benefit to agriculture. Megh Singh, professor of weed science, has initiated comprehensive research to use adjuvants to reduce herbicide leaching by restricting the movement of citrus herbicides in soils and by increasing efficacy of soil-applied herbicides and decreasing applica- tion rate and leaching potentials of the herbicides. Rationale: Many adjuvants have been found to affect herbicide leaching. Both natural and synthetic adjuvants have been tested to reduce herbicide leaching. Disadvan- tages to the use of naturally occurring additives, such as starch, are the lack of reproducible product specifications and bio-erosion of the matrix in the soil, often resulting in inconsistent results. In contrast, better specifications can be achieved easily with synthetic adjuvants. It is also possible to synthesize an adjuvant to fit into a specific situation. Reducing Leaching of Citrus Herbicides With Polymers- Synthetic polymers were found to reduce the leaching of some herbicides up to 25 percent. Polymers inhibiting herbicide leaching all have an anchoring group, which can bind to the negatively charged silicates in the soil, and a balanced hydrophobic-hydrophilic group which will interact with herbicides. Professor Singh has been testing over 30 polymers for their effect on several most commonly used citrus herbicides and found some of them were very effective in reducing herbicide leaching. Reducing Leaching of Citrus Herbicides by Catatonic Surfactants-Certain cationic surfactants were also found to reduce or prevent the leaching of some herbicides in soils. The reduction of herbicide leaching by cationic surfactants was attributed to an increase in absorption of the herbicide onto the soil. It has been suggested that cationic surfactants can replace metals on the mineral surface exchange complex due to ionic attraction of surfactants by soil particles. The mineral surface of the soil is transformed from hydrophilic to hydrophobic by the presence of the hydrocarbon moiety of the sorbed surfac- tant cations. The result can be a great increase in mineral surface sorptivity for neutral organic compounds and a decrease in herbicide mobility. Several families of cationic surfactants are tested by Professor Singh for their potential solution to the problem of herbicide leaching. Reducing Leaching of Citrus Herbicides by Improving Herbicide Efficacy Using Spray Adjuvants-Little atten- tion has been given to the approach of decreasing herbi- cide leaching through reducing herbicide input of available herbicides in soils. The reduction can be achieved by enhancing efficacy of the herbicides. Adjuvants have been demonstrated to enhance efficacy of foliar-applied herbi- cides by tank mixing, spraying deposition, retention, foliar uptake and translocation in plants. Although foliar and soil-applied herbicides are uptaken by plants through different routes, interactions among herbicides, adjuvants and plants occur in both cases. Therefore, weed control efficacy of soil-applied herbicides may be improved by adjuvants. The enhanced efficacy and reduced application rate not only reduce the herbicide leaching potential but also decrease weed control cost. Impact: The studies will lead to reduction of groundwater contamination by herbicides. The use of polymers and cationic surfactants will retain the herbicides in the topsoil and prevent the chemicals then from moving into the groundwater. Growers will benefit directly from this study since farm community is more dependent on groundwater than others. Increased herbicide efficacy by adjuvants will make it possible to reduce application rate of herbicide and therefore the possibility of herbicide leaching to the groundwater. The second major benefit of this research will be the reduction in cost to the growers. By keeping the herbicides in the upper level of soil, polymers can improve the efficacy of herbicides. Improved efficacy makes it possible to reduce rate and number of herbicide applications. Herbicides are expensive chemicals, yet weed control is essential. Retention of herbicides in the soil by polymers, therefore lowers the cost of weed control. Pesticide usage annually on citrus in the U.S. is 34 million pounds and on all crops in Florida is 55 million pounds. Reducing herbi- cide leaching and increasing herbicide efficacy will have tremendous economic and environmental benefits. Retaining herbicides in the plant root zone by polymers will not only reduce herbicide leaching and residues in groundwater but also decrease the total residue level of herbicide in the soil. This is because retained herbicide would be degraded faster in the top soil where activity of soil microorganisms is higher than in the subsoil. Additionally, the information generated from this project may be useful to regulatory agencies, such as DER, FDACS, and EPA to develop the guidelines for proper management of herbicides to minimize the risk of groundwater contamination. Citrus Research and Education Center Megh Singh 10 Selected Research Accomplishments MICROBIOLOGY AND CELL SCIENCE Herbicides That Act By Energy-Drain Mechanisms Situation: The development of new herbicidal agents is an ongoing agricultural priority because of the ability of plant organisms to develop resistance mechanisms and because of increased concerns for environmental conse- quences associated with the use of herbicidal agents. New approaches are needed which depend upon a rational basis for the design of effective agents which will not endanger beneficial microorganisms in the environment, or man and other animals. Rationale: The biochemical pathway which produces the three aromatic amino acids, a number of essential vita- mins, and a variety of specialized plant compounds such as lignin is an ideal target system for the design of new herbicidal agents. The absence of this pathway in man and animals means that appropriate enzyme targets of plants can be attacked with minimal risk. Established differences in the pathway steps and the regulation of these steps between higher plants and microorganisms provides a basis for accomplishing herbicidal effects but not antimicrobial effects. The aromatic pathway functions with a heavy input of energy-rich metabolites such as adenosine triphosphate and phosphoenolpyruvate, and the controlled utilization of these metabolites is essential to overall biochemical efficiency. In higher plants, the attack of a number of mid-pathway enzymes has the potential to disrupt normal circuits of feedback inhibition, thereby triggering a massive energy drain associated with unrestrained entry of high- energy metabolites into the pathway. The mid-pathway attack of other pathways such as ones for histidine and purine biosynthesis are also likely to create very substantial energy-drain consequences. This suggests that energy-drain herbicides which attack the aromatic pathway might function synergistically in combination with energy-drain herbicides which attack other pathways. It is anticipated that the multiple series of events triggered during energy drain would minimize the number of resistance mutations that might occur. Impact: An effective new herbicide has the potential to be of worldwide economic value, as illustrated by N- phosphonomethylglycine (Monsanto's Roundup). In addition, modern molecular-genetic methodology has led to feasible prospects for introducing engineered herbicide- resistance genes into crop plants, thus allowing direct exposure of crop plants to weed-killing agents. Professor Roy Jensen works in his laboratory at the UF/IFAS Microbiology and Cell Science Department. In addition, variations of the same energy-drain strategy can be applied to create antimicrobial compounds which are selectively effective against phytopathogenic bacteria, but not toxic to plants. Collaborators: DOE has provided continuous research support since 1978 for basic studies of the enzymological characteristics of aromatic amino acid biosynthesis in higher plants. This has provided a detailed basis for recognition of unique enzyme targets that can be selected for attack in higher plants. This work has been done in a context of comparative enzymological work with both prokaryotic and eukaryotic microorganisms. The overall program of basic comparative enzymology has been supported by more than $6 million of grant funds from the NIH, the DOE, the NSF, the NASA, the ONR and the USDA. We have collaborated with MetaGene Corp. at Progress Park (Alachua) (supported by several Small Business Innovative Research grants to R.S. Fischer) to pursue the commercial development of our approach for development of new antimicrobial compounds. Microbiology and Cell Science Roy A. Jensen SCHOOL OF FOREST RESOURCES AND CONSERVATION Improved Varieties of Pine Trees for Florida's Forests Situation: Approximately 50 percent of Florida's land mass is forested and of these 16 million acres of forest lands, approximately 200,000 acres are harvested and reforested each year. Small private landowners and forest industry plant nearly 150 million pine seedlings each year 11 Selected Research Accomplishments Professor Tim White studies pine trees at the Austin Cary Forest near Gainesville. and need improved varieties for reforestation that grow faster and are more disease resistant. The Cooperative Forest Genetics Research Cooperative (CFGRP) is a university-industry cooperative composed of 12 companies and agencies working together to develop genetically improved pine varieties for Florida and the lower coastal plain regions of Georgia, Alabama and Mississippi. Since 1950, cooperating members have worked with IFAS scientists to understand and improve the genetic structure of commercially important pine species. Today's varieties yield 30 to 40 percent more volume when harvested and are more disease resistant than their unimproved predecessors. Rationale: The cooperative nature of the research and development activities of the CFGRP ensures: (1) High quality, well-directed projects that must be approved by all members; (2) Sustained productivity through economic cycles due to collective commitments; (3) High leveraging of research dollars invested because participating members contribute money, land, equipment, personnel and scientific expertise to the overall effort; and (4) Immediate application of research results to a large land base. Impact: Approximately 95 percent of all timberlands reforested in Florida use genetically improved varieties developed through the CFGRP breeding program. Assum- ing 200,000 acres are planted each year, the annual future value of the incremental wood harvested through use of these varieties in the State of Florida is approximately $72 million (assuming each newly planted acre is harvested in 25 years with an incremental yield due to genetic improvement of 30 percent or nine cords and a real stumpage value of $40 per cord). Discounting this future value back to 1995 dollars (at a 6 percent real discount rate), the annual value of this program to the State of Florida is approximately $17 million. Collaborators: In addition to scientists and technical staff in IFAS, continuing members of the CFGRP are both government agencies and private companies.

School of Forest Resources and Conservation Tim White Fertilization and Nutrition of Southern Pines Situation: Forestry is a vital part of the economy in Florida and the Southern United States. Recent estimates for the South indicate that there are over 28 million acres of forest land, and about one-third of this total is covered by pine types. Population increases and changing land-use patterns have reduced timberlands in this region b. about 2.5 million acres since the 1960s. Such trends suggest that productivity on remaining timberlands must increase it future demands for forest products are to be met. One ot the single most important factors regulating productivity of pine stands in Florida and the southeastern lower Coastal Plain is soil nutrient availability. Silvicultural activities such as forest fertilization provide the means for increasing fiber yields and sustaining high levels of forest productivity. Associate Professor Eric Jokela examines a young pine tree in his lab at the UF/IFAS School of Forest Resources and Conservation. 12 Selected Research Accomplishments The Cooperative Research in Forest Fertilization (CRIFF) program is a university-industry research effort composed of 10 forest companies working collectively with UF/IFAS scientists. The cooperative was initiated in 1967, with the overall research goal of assisting forest managers and non- industrial private land owners in making the most effective use of their lands and soil resources for wood production purposes. Rationale: Research support has been utilized to help establish, maintain, and analyze over .300 experiments on cooperator's lands throughout Florida and the Coastal Plain of the southeastern United States. These experi- ments have been designed to relate tree growth responses from forest fertilization and other silvicultural activities to soil and stand properties. Information gained through this research has played a critical role in providing land managers with operational recommendations for forest soil management, with emphasis on forest fertilization and tree nutrition. Impact: Research results have demonstrated that silvicul- tural practices such as forest fertilization and competition control can result in sizeable gains (15-50 percent) in forest productivity. Of the 16 million acres of forest land in Florida, approximately 4 million acres have been estab- lished in pine plantations. A single mid-rotation applica- tion of fertilizers would be expected to produce about four cords per acre more wood than a non-fertilized plantation at the end of a 25-year rotation. Assuming that about one third of these pine plantations were established on nutrient deficient sites and that the stumpage value of wood was $40 per cord, the potential annual value of this research program to the State of Florida is about $8.5 million. Given the worldwide importance of wood fiber, results from these research efforts have direct benefits to society, especially as related to increasing economic returns from investments in forest management, and the development of environmentally sound forest management practices used to increase forest productivity on a declining land base.

SOIL AND WATER SCIENCE Effect of Forest Harvesting on Water Movement and Water Table Fluctuation in Florida's Flatwoods Situation: Much of Florida's commercial forests grow on high water table soils. Several important questions are being addressed whose answers will affect the classification of these lands, their ultimate use as comninercial forests, and the environmental effect of manage- men t: .i -A~t Il i (I r, )i ..~'d J 1) This study is addressing the ;.. - question of how much of Professor Nicholas Comerford this landscape measures the water table in a well. would and could be classified as forested wetlands. 2) This study is addressing the question of how does the water flow patterns and water table fluctuation change when these areas are harvested for commercial products. 3) This study is addressing the question of how long does it take for the patterns of water flow and water table fluctuation to rebound to pre-harvest levels. 4) This study is addressing the question of whether the water tables will be lowered with increased manage- ment of newly planted forest stands. Rationale: Commercial forestry is a large industry in Northern Florida. The large block ownership, in turn, helps preserve forest ecosystems in this state and has the potential to be stewards for Florida's waters and wildlife. Much of lands managed for commercial forests has been considered wetlands by many, yet it has not been clear how much of area would really make the regulatory wetlands designation. Answers to the question listed above will School of Forest Resources and Conservation Eric J. Jokela 13 - -- 0 M6 Selected Research Accomplishments determine the classification of landscapes that support commercial forestry, will determine the effect commercial forestry has on one component of the state's water re- sources, and will determine the time frame that changes caused by harvesting will be sustained. Such studies require the cooperation of forest industry and the universities of the state. The industries supply the land and the manage- ment of the land while the universities supply the expertise to evaluate and solve the problems. Impact: Social impact: The large block ownership of much of the states commercial forest land provides a significant input to the job market of communities in North Florida. A loss or change in the industry due to management effects will decrease or change the jobs and subsequently change the social structure of many smaller towns in the state. Likewise, the paper mills in many of our cities, like Jacksonville and Fernandina Beach depend on the production of pulp from these lands. A change in production due to limitations on harvesting will change the job markets and social structures of areas within these cities. Economic impact: The value of standing timber cut in the southern United States was over $3 billion in 1984 and has increased since then. The value added by processing increased the roundtimber value to $6.1 billion in 1984. This was two-fold the value of soybeans and cotton and threefold the value of tobacco, wheat or corn. If manage- ment practices, and hence productivity, were to change due to the wetlands designation of the landscape or the on-site and off-site impacts of management then it could change this economic picture substantially. The result would depend on the effect changes had on (1) the level of productivity and (2) the economic inputs to achieve a level of productivity.

The integrity of these ecosystems is threatened by complex water management problems resulting from the demands by agriculture and urban users, which often conflict with optimal management and conservation of natural resources. Rationale: Wetlands and lakes serve as sinks, sources and transformers of nutrients and other chemical contami- nants, and as such they can have a significant impact on water quality. The primary driver of these processes is the ecosystem biogeochemistry, which includes chemical, biological and physical processes in sediment/soil and water column. Phosphorus is one of the key nutrients regulating the eutrophication of these ecosystems; thus much of the research effort was focused on basic under- standing of the phosphorus biogeochemistry as related to water quality. Research and education in this area is critical in developing optimal management strategies to protect these natural resources. Impact: Key research issues addressed include: (1) nutrient loading impact on wetlands and streams in the Lake Okeechobee Basin; (2) internal nutrient cycling and loading in Lake Apopka and Lake Okeechobee; (3) historical nutrient loading impacts in the Everglades; and (4) long-term nutrient retention capacity of constructed and natural wetlands. Results obtained from these studies are now used by Water Management Districts in formulat- ing policy and regulation, and developing management strategies to protect these natural resources. Historical phosphorus accumulation rates measured in the Everglades played a key role in designing stormwater treatment areas (STA) to protect the Everglades, as part of the settlement and urban development.

Ramesh Reddy VETERINARY MEDICINE A Better Understanding of the Metabolic and Reproductive Changes That Occur in Dairy Cows Having Calving-Related Disorders Has Contributed to a Treatment Strategy That Improves Fertility in Cows Having Complications at Calving Situation: Calving-related disorders in dairy cows such as milk fever and retained placenta cause significant mon- etary losses to dairy producers in Florida. These hypocalce- mic-related disorders prolong the period of uterine involu- tion and postpartum anestrus by predisposing the cows to metritis. Cows affected with metritis have been docu- mented to produce less milk and have impaired fertility. Rationale: In an experiment conducted by Carlos Risco, Maarten I)rost of UF's College of Veterinary Medicine, and William Thatcher of UF's College of Agriculture, Department of Dairy Science, the relationship between prostaglandin F2 alpha (a product of metritis) and calcium activity in dairy cows affected with retained placenta and milk fever was related to uterine involution and ovarian activity. Results obtained from this experiment demon- strate that cows affected with retained placenta are hypocalcemic during the early postpartum period, have Assistant Professor Carlos Risco takes a blood sample from a cow for his research in veterinary medicine at the UF/IFAS Dairy Research Unit. elevated serum prostaglandin levels and normal uterine involution. This information suggests that the common practice of exogenous prostaglandin treatment soon after calving in cows with retained placenta in an attempt to promote uterine involution should be reconsidered, and that calcium treatment may be warranted in these cows. This study also demonstrated that cows with milk fever have delayed uterine involution and ovarian activity post partum associated with a greater loss of body condition. During the past five years there has been an increased use of gonadorelin releasing hormone (GnRH) and prostaglan- din F2 alpha (PGF) by veterinarians in an attempt to restore fertility in dairy cows having metritis as a result of dystocia and retained placenta occurring at calving. However, results from these type of studies have been conflicting. Carlos Risco and Louis Archbald of UF's College of Veterinary Medicine examined the use of GnRH and PGF in dairy cows with postpartum metritis related to dystocia and retained placenta. The study was unique because of the large number of cows used and a clearer definition of metritis. Results from this study indicate that dystocia and retained placenta are more important factors in determining subsequent fertility than uterine condition early post partum. In addition, the used treatment of GnRH around day 14 post partum does not help restore fertility in cows affected with dystocia and retained placenta, and that a single treatment of PGF around days 14 and 26 post partum improves fertility in dairy cows affected with these conditions. Impact: The dairy industry in Florida has an economic impact of over $500 million per year (1993 figures). Infertility causes significant financial losses to Florida dairy farmers from loss in milk production and replacement costs. Our work documents that the use of prostaglandin improves fertility in dairy cows enabling dairymen to maximize reproductive efficiency in their herds. Prostag- landin is an inexpensive hormone approved by the FDA tor use in lactating cows and is available throughout the world.

Risco CENTRAL FLORIDA REC Bacterial Fruit Blotch of Watermelon Situation: Watermelon fruit blotch, a seed-borne bacterial disease, has occurred in Florida every year since 1989, and in some years, has been devastating in other Eastern States 15 Selected Research Accomplishments Bacterial fruit blotch of watermelons is being studied by Professor Donald L. Hopk/ns at the Central Florida REC. that produce watermelon. Fortunately, fruit blotch has been limited to less than 5 percent of the Florida water- melon acreage, but losses have been as high as 90 percent in fields that have it. Individual growers have suffered losses as high as $150,000. Yearly production losses to the $80 million Florida watermelon industry from bacterial fruit blotch probably have averaged a little less than $1 million. The biggest threat from this disease results from the litigations against seed companies and transplant growers for the introduction of the bacteria into commer- cial fields. There have been single lawsuits in Florida for more than $1 million, and there currently are 37 outstand- ing lawsuits in South Carolina. These litigations caused seed companies to temporarily suspend the sale of water- melon seed in the U.S. in the fall of 1994. Excessive liability could result in companies refusing to sell water- melon seed in the Eastern U.S. permanently, or until this disease problem is solved. If this happens, there could be no $80-million watermelon industry in Florida. Rationale: There must be seed production methods and seed testing methods developed that will allow watermelon seed producers to know that their seed is free of the watermelon fruit blotch bacterium. Seed treatments to eliminate the bacterium need to be developed. Sensitive assays for seed contamination must be devised, perhaps using selective media and new molecular techniques such as the polymerase chain reaction (PCR). For the instances where the bacteria gets into the field despite the best efforts to use clean seed, there needs to be control options available to the grower. Impact: By developing this technology for producing disease-free seed, the litigations will subside and seed companies will be able to continue selling watermelon seed profitably, thus allowing this $80-million industry to continue in Florida. The field control of the disease, perhaps with copper-containing fungicides, will allow the watermelon grower to prevent those total losses of $100,000, or more, and the industry to prevent the yearly loss of approximately $1 million.

Hopkins CITRUS REC Minimizing The Impact of Fruit and Foliage Diseases of Citrus Trees Situation: Florida's hot, humid climate is extremely favorable to the proliferation of fungi and the development of diseases. Some of these diseases affect only the external appearance of the fruit, and thus are only important on fresh-market varieties. Others may have serious effects on yield. Greasy spot affects most varieties and almost the entire citrus acreage and causes premature defoliation, tree morbidity and reduced yields if not controlled. Postbloom fruit drop affects flowers causing drop of fruitlets and can be severe if rains occur during the bloom period. Alternaria brown spot is limited to tangerines and its hybrids but is severe in rainy years causing fruit drop and disfiguring fruit lesions. Melanose and scab do not reduce yields but cause unsightly blemishes, especially on grapefruit and some tangerines. Impact: Fungal diseases are controlled primarily by applications of fungicides with the number of treatments ranging from a single application per year on oranges for juice to several in grapefruit and tangerines for the fresh market. Each application costs from $40-50 per acre. Fungal diseases may reduce packout of fresh fruit and thus returns to the grower. For example, on grapefruit marketed over the last five years, each 10 percent reduction in packout decreased returns to the grower by over $800 per acre. Losses to postbloom fruit drop have been localized, but some growers have experienced yield reduction of 50-90 percent on Navel oranges. Alternaria brown spot has become so severe on Minneola tangelos that orchards are being removed and replants with potentially less profitable varieties. Rationale: The emphasis of the research programs on fungal diseases is to develop a thorough understanding of 16 Selected Research Accomplishments Professor Lavern Timmer examines foliage damage that his research is helping to eradicate. the causal fungi and the environmental conditions favorable to disease development. Thus, cultural practices can be modified and fungicide treatments can be applied in a timely manner to minimize losses. When postbloom fruit drop appeared in Florida for the first time in 1983, a large program was developed which determined and character- ized the causal fungus, described the disease cycle, deter- mined the means of survival between bloom periods and the means of spread. A predictive model was developed to properly time fungicide applications and avoid unnecessary sprays. Copper fungicides are the most important products for disease control. They are very safe for applicators and consumers and highly effective for control of melanose and greasy spot. However, they do accumulate in the soil and may become toxic to trees. Products with reduced copper content and lower rates of standard materials have been evaluated for disease control. Use of low rates and frequent applications have improved disease control without increasing the amount of copper applied. Micronutrient sprays have been found useful for greasy spot control and may help reduce the amount of copper applied for that disease. Newer, more environmentally friendly fungicides, many of biological origin, are being evaluated for disease control on citrus. Future research will be directed at more accurate definition of environmental conditions for disease development with the aim to produce predictive models which can minimize sprays and maximize disease control. Sources of resistance exist in citrus germplasm for Alternaria brown spot and scab which can be incorporated into commercially desirable varieties. Citrus REC, Lake Alfred Lavern W.

This project evaluated an alternative approach to disease control by investigating the effect of an element found in varying concentrations in plants, silicon, on several rice diseases such as blast. Rationale: Silicon is one of the most abundant elements in the earth's crust, and most soils contain considerable quantities of this element. However, repeated cropping can reduce the levels of plant-available silicon to the point that supplemental silicon fertilization is required for maximum production. Low-silicon soils (Oxisols and Ultisols) are typically highly weathered, leached, acidic, and low in base saturation. Organic soils (Histosols) are also considered low-silicon soils. These soil conditions are commonly found in crop producing areas of the Southeast- ern US., Brazil, Colombia, and other areas of Latin America, Africa, Asia and Australia. Silicon is known to reduce the severities of blast, brown spot, scald and other rice diseases. Recently, research demonstrated that silicon will enhance host plant resistance and control blast as well as brown spot to the same degree as a fungicide. Economic: Our growers know that if they have amended the soil with a plant available silicon source they do not Selected Research Accomplishments application is about $16 per acre. If applied at two times per season on about 80 percent of the 22,000 acres of rice planted and amended with silicon, the cost would be about $563,200. Thus, this research has saved the rice growers over half a million dollars annually. Social and environmental: The general public is in favor of production systems that offer alternatives to chemicals such as fungicides. Silicon fertilization represents such a system. In fact, international research centers such as International Rice Research Institute (IRRI) and Interna- tional Center for Tropical Agriculture (CIAT) have been interested in this research and we have been cooperating with CIAT for the past four years on several aspects.

Datnoff Implementation and Verification of Best Management Practices for Reducing Phosphorus Loading in the Everglades Agricultural Ar Situation: The Everglades Agricultural Area (EAA) is respon- sible for over $1 billion a year in economic activity in south Florida. The organic soils of the area are conducive to the growth of a variety of crops including sugar- -- cane, winter vegetables, sod and rice. The abundance of 1 IIH ^I FB **---^t^ ^B^ ^^^ water has, in the Professor Forrest Izuno is keeping an past, added to the eye on the ecosystem in the Florida desirability of Everglades. farming in the EAA. Within the past 20 years, much attention has been focused on the effects of agricultural drainage water on the South Florida environment. Many blame agricultural activities in the EAA for the real and perceived negative impacts on these protected environments. The primary causes of the negative impacts have been identified as elevated levels of phosphorus (P) in agricultural drainage water and changes in the wetland hydroperiods. Best Management Practices (BMPs) are being developed as cost effective methods of partially mitigating both water quality and quantity problems. Rationale: The water quality and quantity problems being experienced by south Florida are the foci of great amounts of effort and research resources provided by local, state and federal government groups. The Everglades issue is perhaps the single most important agricultural/environmental problem in the United States. The solution to the problem as well as the methods of developing a solution are being watched closely by farmers and environmentalists across the America. Many look at the Everglades issue as a barometer of the sustainability of agriculture in the face of mounting environmental concerns. Granting agencies continue to supply research dollars in excess of $500,000 per year in support of the program. Support resources are necessary to maintain a basic services framework under which the research can be performed in an expedient manner. Impact: The cessation of agricultural production in the EAA would cause the loss of countless jobs and reductions in state and personal revenues eclipsing $1 billion annu- ally. Entire cities bordering Lake Okeechobee would simply cease to exist. The research program offers practical solutions that will enable agriculture and the environment to coexist. Best management practices reduce phosphorus loading and demands on water resources, while actually optimizing the usage of water, chemicals, and energy. A large portion of the ecosystem native to the Florida Everglades can be preserved as a national resource, continuing to exist as a tourist attraction, and natural habitat to indigenous flora and fauna. Costs of Storm- water Treatment Areas (STAs) are estimated to be $ 400 million based on a 25 percent agricultural P load reduction. Loading reductions near the 40 percent level could reduce STA costs by at least $150 million.

Rationale: Unlike many agricultural crops, Associate Professor Monica Elliott the number of turfgrass researches turfgrasses at the UF/ IFAS Fort Lauderdale Research fungicides has remained and Education Center. the same with older products being replaced with new fungicide chemistry. Due to the accessibility of fungicides and the significant influence of the chemical industry, turfgrass managers were relying more on chemi- cals than on cultural controls for disease management. A program was required to reinforce the effectiveness of an integrated approach for disease control. Impact: Based on interactions with the golf course industry, fungicide use for control of bermudagrass decline (a root rot disease) has declined significantly. Our research indicated that: (1) the single most important disease control was simply to raise the cutting height, and (2) many of the triazole fungicides currently available can have a negative impact on turfgrass quality which ultimately requires greater inputs for turfgrass culture. In other words, fungicides can hurt as much as they can help. Turfgrass managers have been taught, via field research, that they must act as informed consumers in selecting and using the appropriate fimgicide. Reduction in fungicide use by managers decreases environmental exposure to these products in an urban setting. They have also observed that cultural practices influence, both good and bad, the localized environmental parameters that affect turfgrass disease development.

Research and Education Center. Despite the use of the large quantity of termiticides (5-10 kg per single family home), this technique does not affect the vast population of subterranean termites in soil. Rationale: The termite research project at the Fort Lauderdale Research and Education Center, IFAS/UF was created in 1985 to study the biology of termite pests and to develop better control techniques. The project has been supported by an annual investment of about $100,000 in state tax dollars. Since its inception, the project has attracted a total of $1.5 million grants from industry and government agencies. Impact: The termite research project developed a moni- toring/baiting station to deliver an insect growth regulator (IGR), hexaflumuron, to the vast populations of subterra- nean termite colonies near a house. The system typically uses less than one gram of IGR to eliminate a colony of several million termites. The technique will drastically reduce pesticide use for termite control (>10,000-fold). Elimination of termite populations near a home will save homeowners in the U.S. as much as $1 billion in repair 19 Selected Research Accomplishments and re-treatment cost.

Fort Lauderdale Research and Education Center Nan-Yao Su NORTH FLORIDA REC New Techniques Allow Screening for Resistance to an Old Disease Situation: The plant pathogen Sclerotium rolfsii, first found on tomato in Florida in 1892, is a soilborne fungus that causes major diseases on tomato, pepper, peanut, cotton, soybean, most cucurbits and other crops in temperate regions worldwide. Yield losses to this pathogen can be very high, requiring fungicides and fumigants to minimize losses. Where control measures are inadequate yield losses of 10-25 percent may be encountered and losses as high as 66 percent have been measured in peanut research plots. Screening for resistance to this pathogen has always been a problem. Rationale: The ideal control for plant diseases is resis- tance. Screening for resistance to this pathogen in the greenhouse or field has always yielded erratic results. Techniques were needed that would allow consistent, systematic evaluation of plant resistance to this pathogen. Approximately 10 years were spent at the NFREC, Quincy, and Marianna, using peanuts as a model to test these techniques. Impact: Three inoculation techniques were developed that consistently work in the greenhouse and field. Two techniques allow evaluation of individual plants. 1. The fungus may be grown on sterilized clothespins impregnated with potato dextrose agar as a food base. Individual 'pathogenic' clothespins can very quickly be clamped around the base of a plant stem. 2. Individual sclerotia of the fungus may be I germinated on potato dextrose agar disks and placed next to the base of plant stems. A third technique applies to larger plantings. The fungus is grown on sterilized oat seed which can be bulked with rolled oats and applied to the field. All of the techniques can allow individual plant assessment in the field. Temperatures from about 80 F to 95 F and irrigating with about one-half inch of water is adequate for consistent disease development. The oat seed technique is also effective for investigating the effectiveness of chem- The plant pathogen Sclerotium ical or biological rolfsii on peanuts is being control measures. researched by Professor F.M. control measures.

Present law states that all use of methyl bromide in the U.S. must end Jan.1, 2001. Methyl bromide is an important soil fumigant in many Florida production systems, particularly fresh market tomatoes. Fresh market tomato production was valued at $594 million in 1993, 53.3 percent of the total U.S. crop value. Most all of the 25,000 acres in tomatoes are fumigated each year with methyl bromide. Without alternatives to methyl bromide, 20 Selected Research Accomplishments ~v ~.'.4 w ~ *7'k 9. Rationale: Many projects are underway to develop alternatives to methyl bromide.

To plastic mulch. prepare for both crops, each field is fumigated with methyl bromide and then the planting beds are covered with plastic mulch. Soil solariza- tion is a cultural practice that may reduce the need for methyl bromide. Presently, the beds are formed and tarped in early June in preparation for the fall crop. New research has shown that if certain clear plastic is used, rather than the traditional white plastic, the suns rays will heat the soil sufficiently to kill tomato pests. The energy from the sun is trapped in the beds, causing the temperature of the soil to reach up to 135 F at the surface to 100 F at a depth of 10 inches. After six weeks of these extreme temperatures, the pests in the soil have been killed similar to what would have occurred if methyl bromide had been used. When the tomatoes are planted in the summer, the plastic is painted with to reduce the soil temperature, thus protecting the tomato's roots. Impact: Large plots are already being established by growers in the Quincy area. If this proves to be successful, it will provide an alternative to methyl bromide for the fall tomato crop. This is critical for the industry to continue. This is also one of the first examples of a production system that can fully utilize the benefits of solarization, a method of soil treatment that was first develop in Israel over 20 years ago.

With the release of SunOleic 95R in 1995, UF has provided the peanut industry and the U.S. consumer with the first high oleic peanut cultivar. SunOleic 95R has 80 percent oleic (18:1) and 2.5 percent linoleic (18:2) fatty acid content of its oil, compared to 55 percent (0) and 26 percent (L) for Florunner. This trans-lates into significant shelf-life improvement (3-15 fold) for peanut products from this cultivar. This oil chemistry is comparable to olive oil. UF research has shown that this peanut, as part of a low-fat diet, can be helpful in reduction of LDL cholesterol levels in individuals with this problem. Rationale: Considering the importance of peanuts in Florida and the southeast USA production area and the above mentioned success of the breeding program, the UF Agricultural Experiment Station has continued funding this program for over 65 years. In the late 1970s and the early 1980s, Florida peanut cultivars occupied about 75 percent of the total U.S. acreage and still occupied about 40 percent of this acreage in 1994. Importance: The potential impact of the SunOleic 95R and future UF peanut cultivars with this chemistry could be tremendous. It will provide consumers with a healthier peanut which should stimulate consumption, which has declined in recent years. Manufacturers will benefit from extended shelf-life and reduced product recall. This shelf- life benefit could stimulate product development and cause manufacturers of peanut products to revisit packaging Selected Research Accomplishments methods and possibly extend marketing areas, especially internationally. All of this should directly benefit Florida consumers, as well as the peanut industry. This cultivar could occupy the majority of the southeast production area by 1997.

Gorbet SOUTHWEST FLORIDA REC Using Compost to Recycle Municipal Organic Wastes Situation: The disposal of common municipal solid wastes (MSW) like yard trimmings and household garbage has become more complex and expensive due to difficulties in siting new landfills as older ones approach capacity. Florida generates over 20 million tons of MSW each year, and will produce more as the population increases. Other environ- mentally-acceptable disposal methods other than landfilling need to be explored. One alternative is to recycle the organic wastes by turning them into compost, which can be used as an amendment to improve Florida's sandy soils. Composting is being encouraged as a solid- waste disposal method because returning the composted Associate Professor Thomas Obreza is shown with tomato plants grown in MSW compost soil at UF/IFAS's Southwest Florida Research and Education Center in Bradenton. products to the land recycles organic back to the site where they originated. Rationale: The importance of organic matter to soil productivity, especially in sandy soil, has long been recognized. Adding a high rate of MSW compost to a soil can potentially improve its physical, chemical, and biological properties. The recent focus on compost production will eventually provide large quantities of material that could be used to improve soil quality. It is assumed that agriculture and horticulture will be the primary users of Florida composts, but a market will not exist unless high-quality materials are produced that have demonstrated product value, and are affordable. Impact: Biodegradable organic that could be composted comprise about 60 percent of Florida's waste stream, or about 11 million tons annually. Composting these materi- als would reduce the necessity for municipalities to build expensive new landfills or incinerators, and would generate about 6 million tons of soil amendment. Tomato and watermelon yields increased in response to MSW compost additions at the SWFREC in Immokalee. Soil water- holding capacity, pH and nutritional status increased where compost was applied, as did the soil's ability to retain phosphorus fertilizer against leaching. Plant growth was inhibited where immature compost was used, which emphasized the need to inform potential compost users of the potential drawbacks of compost use as well as the positive aspects. Collaborators: Compost research at the SWFREC in Immokalee was part of a statewide comprehensive com- post-utilization program under the direction of the UF/ IFAS Center for Biomass Programs.

The widespread assimilation of zebu breeding into 22 Selected Research Accomplishments commercial beef herds throughout the southern and warm regions of the U.S. attests to the economic value placed on tolerance to heat, humidity and diseases including external and internal parasites.

Rationale: There are alternative sources of beef cattle germplasm from other countries that are adapted to tropical environments that have not been characterized under U.S. conditions. Priority should be given to the characterization and evaluation of tropically adapted beef cattle germplasm that has potential for increasing produc- tion efficiency, especially reproductive efficiency, and potential for improving marketability. Over the last decade the Senepol, a tropically adapted Bos taurus breed has been evaluated at STARS. As evaluations of the Senepol are finishing, other breeds have been identified for evaluation. These breeds include the Tuli, a sanga breed native to Africa, and the Romosinuano, a criollo breed native to Colombia. Impact: Research results suggest that under conditions in Florida, the tropical adapted Bos taurus breeds, Romosinu- ano and Senepol, could contribute reproductive traits more similar to temperately adapted Bos taurus than tropically adapted Bos indicus breeds without sacrificing tropical adaptation. Although post weaning level of nutrition affected age at puberty in heifers, age at puberty averaged across breeds was greater than 18 months of age. Brahman and Nellore x Brahman heifers did not reach puberty until nearly two years of age, which was later than all other breeds studied. Tropically adapted Bos taurus breeds such as Senepol and Romosinuano reached puberty at younger ages than tropically adapted Bos indices breeds (Brahman and Nellore x Brahman). Like Brahman, Senepol and crossbred Senepol cattle were shown to be more heat tolerant than temperately adapted breeds during summer in subtropical Florida. Levels of heterosis between Hereford c rS 23 ., '- and Senepol were substantial and approached levels reported for Bos indicus x Bos taurus crosses.

Ratoon stunting disease is considered to be the most important disease of sugarcane on a worldwide basis, and losses due to the disease in Florida are estimated at over $30 million annually. Accomplishment: Research scientists at UF have shown that ratoon stunting disease is caused by a very small bacterium that infects the water conducting system within sugarcane plants resulting in stunting of infected plants. After studying the reaction of plants to the pathogen for more than 10 years, Professor Michael J. Davis and colleagues at IFAS have developed a method to breed for resistance to the disease in new varieties. This method is Selected Research Accomplishments based on measuring the extent of colonization of plants by the pathogen using a technique developed at the university called the tissue-blot enzyme immunoassay. The breeding method has now been incorporated into the joint breeding program of UF, the USDA and Florida Sugar Cane League. Impact: It is likely that this technique will be used to develop resistant sugarcane varieties for use throughout cane growing areas of the United States and elsewhere. This will permit the production of sugar on less land and lower the cost of this nutrient to consumers. Collaborators: Agricultural Research Service, USDA Tropical Research and Education Center M.J.

Additionally, in an attempt to restore the a natural ecosystem of the Everglades, Professor Bruce Schaffer checks soil the South Florida where fruit trees will be planted at the Water M anage- UF/IFAS Tropical Research and ment District Education Center in Homestead. and the U.S. Army Corps of Engineers plan to increase water flow from Lake Okeechobee to Florida Bay. This will raise the water table (for at least part of the year) in much of the agricul- tural area that is used for tropical fruit production. For tropical fruit production to continue in these areas, it is essential to identify species or cultivars that are adapted to south Florida conditions and that can tolerate cyclical flooding, and to improve the capacity of economic plants to be highly productive under these conditions. Therefore the mechanisms of flood-tolerance for individual crops must be determined. Also, often flooding-stress in trees is not due only to lack of oxygen, but the result of root pathogens which are more damaging when roots are water- logged. Therefore, it is often important to consider waterlogging to pathogen interactions in studies on the effects of flooding of fruit crops and in devising methods of amelioration. The research has shown that crops such as carambola and mango can tolerate some flooding, whereas avocado is flood-sensitive. In Dade County soils, there is a strong additive effect of Phytophthora root and flooding on avocado. Phytophthora infection is not a serious problem in these soils under non-flooded conditions, whereas it is devastating under flooded conditions. Thus, treating avocado with certain fungicides can reduce the chance of tree mortality under flooded conditions. Also Phytophthora-resistant avocado rootstocks from California have been shown to be promising. In other crop catego- ries, flood-tolerant species and cultivars are being identi- fied. For example, using pond apple (a "swamp-loving" Everglades annona species native to the Everglades) as a rootstock for commercial annonas such as atemoya may produce flood-tolerant, commercially productive tropical fruit trees. Impact: Ultimately this work will allow tropical fruit production to be profitable in areas which are now mar- ginal for crop production due to flooding. This will help maintain a place for agriculture in an area faced with increasing urbanization and with the need to elevate the water table in order to restore the Everglades to 19th- century conditions. Collaborators: USDA Special Grants in Subtropical/ Tropical Agriculture (CBAG) Tropical Research and Education Center Bruce Schaffer Integrated Production Systems Adopted by Commercial Vegetable Growers Situation: In 1970, about 20,000 acres of tomato were grown with multiple fertilizer application and sprinkler irrigation to produce about 6.8 million cartons of fruit. About 7,000 snap beans produced about 1.25 million bushels and 2,900 acres of squash produced about 0.44 million in 1970. Preventive foliar sprays were applied frequently to control insect and disease pests of tomatoes, bean and squash. Crop yields were adversely affected by soil-borne diseases and fruit rots. During the 1970s and 1980s research at UF/ TREC led to the development of several integrated production systems that were adopted by the vegetable crops industry that lost 2,000-plus acres to urban expansion (blight) and 6,000 acres to government land acquisition for the Everglades National Park. Impact: Bedding systems utilizing plastic mulch, fimiga- tion and drip irrigation enhanced control of weeds and soil-borne diseases, and fruit rots reduced irrigation requirements by over 200 percent and more than double 24 Selected Research Accomplishments yields when UF - developed a plug- : l mix planting system, which provided a 4.: method for ' mechanically planting seed r through plastic mulch, 90 percent of Dade County tomato produc- tion was con- verted to plastic mulch, and fumigation within three years in the early 1970s.

Multiple, sequential cropping research on plastic mulch, initiated at TREC in the mid 1970s was rapidly utilized in other areas of the state in the 1980s and growers in Dade County began following tomato crops with one or two squash or cucumber crops on the same mulch drip system in 1990. Principles used in the UF designed punch planter" enhanced the industry's acceptance of the multiple- cropping system. UF/TREC research on gel seeding of pregerminated seed led to the development of a more efficient (closed) burner to burn planting holes in plastic mulch. This burner is used on 90 percent of the plastic mulched crops grown in rock soils. Under-bed trenching research with vegetable at TREC in 1985 allowed deeper penetration of root system, enhanced plants utilization of aquifer water with reduced requirements for irrigation. Integrated pest management (IPM) research in vegetable crops initiated at UFfFREC in the mid-1970s led to scouting techniques and development of insect threshold levels for many vegetable insects now used by commercial Florida IPM firms. As a result of IPM practice used or vegetable in Dade County, reduced levels of pesticides are applied to crops providing an economic advantage to growers that use IPM and a health advantage to consumers who purchase the produce. These integrated systems have enabled Dade County tomato growers to produce 7.5 million cartons of tomato from 5,500 acres annually during the first half of the 1990s; i.e. 25 percent of the 1970 acreage produced 10 percent more tomatoes in the 1990s.

Close spacings early in an orchard's life increased per acre yields and returns. However, after 10 to 15 years trees would compete with each other for light, water, and nutrients; and therefore periodic topping and/or hedging or tree thinning would be required to maintain productive tree canopy, yields, and orchard profits. Unfortunately, most producers delayed tree size control and/or removal practices, and consequently fruit yields and quality declined steadily (to 1 or less bushes per tree). Rationale: Florida had about 9,000 acres of avocados before Hurricane Andrew, 6,000 now. Much of it was mature, but yields were very low (one bushel per tree average). Rejuvenation of mature non-productive orchards through selective tree removal and topping was proposed as a possible solution to re-establishing productive tree canopy, increasing yields, and improving fruit quality. However, this had not been demonstrated nor documented to be effective, reliable and economically advantageous. .. ' Associate Professor Jonathan Crane closely examines the skin condition of an avocado at the UF/IFAS Tropical Research and Education Center in Homestead. 25 Selected Research Accomplishments Impact: A 4-year field trial was established with a cooper- ating avocado grower to assess a planned orchard rejuvena- tion program (topping, selective tree removal) on one upright and one spreading growth habit avocado cultivar, respectively. Re-establishment of productive canopy, crop yields, and costs of rejuvenating the trees were recorded. Three grower field days were held to demonstrate results to the avocado industry. The trial demonstrated the feasibil- ity (economic and practical) of rejuvenating non-produc- tive avocado orchards with spreading growth habit cultivars and the questionable economic advantages of rejuvenating avocado orchards with upright growth habit trees. Results were also presented at an avocado growers seminar, the Florida State Horticultural Society annual meetings, and at individual grower visits. Currently about 70 percent of the industry is practicing periodic topping and hedging to maintain trees at a height (usually 12-22 ft.) that maintains the lower productive canopy and crop yields. Far fewer growers (perhaps 5 percent) are practicing selective tree removal to allow remaining trees to maintain productive lower canopy. Impact 1. maintain and increase mature orchard production; 2. maintain and improve fruit quality; 3. maintain and increase producer profits.
