of a handmade "Gator" quilt. The entire Center
participated with the photos that became part
of a scrapebook.
The program continued with Dr. Duncan
asking who had anything to share about Shelby
and almost everyone stood and joined the line to
express their personal feelings about Shelby. Dr.
Fred Gmitter told a story about as a child being
sent to the principal's office and after coming
out of the office feeling pretty downtrodden,
there would be Miss Willow to make everything
feel better."You're my Miss Willow"' Gmitter said
to Shelby. That sentiment was shared by other
faculty as well, after being called to task by the
Director. "Shelby's smile and positive attitude
always made us feel better,"they said.
Shelby, our sincere thanks and best wishes
for your retirement.


On April 2, 2009, representatives from allied citrus
industry groups, fellow researchers, friends, and family
came together to honor Dr Harold Browning for his
accomplishments with both CREC and the industry More
than 200 guests attended Browning's send-off, of which,
Dr Browning has worked with in one capacity or another
In addition, many IFAS cleans and department heads joined
in the well wishes extended to Dr Browning
Originally only planning on the Center Director's
position for 5 years, Dr Browning spent the last 12 years
working hard and long hours and has accomplished much
for UF IFAS CREC, Floriia Citrus Growers, and other areas
of the citrus Industry After 20years at CREC, he has decided
to take a new career direction
In an Interview with Gary Cooper of Southeast AgNet,
Dr Browning stated,"Well you know time flies when you're
having fun, so years have passed and it's time to be looking
at new opportunities, so I'm looking forward to moving
on to a new page in my caieei and with some tiepication
about leaving a job that I've really enjoyed in Floriida It

is a change, but is one that takes me back to my original
Interests biology and applied ecology"
Spearheadced by Gary Cooper of Southeast AgNet, the
Industry purchased a Cabela's giftcaid which was presented
to Dr Browning to enjoy stocking up on fishing gear and
other equipment Dr Browning was also presented with
a characterization of himself fishing and a plaque honoring
his service and dedication to the citLus inCdustry
Dr Browning and his wife, Nancy, will be spending
time out west "Now is the chance to turn a page and

Drs. Megan Dewdney and Pete Timmer traveled to
Ghana in late September 2008.Theywere accompanied
by Antonio Vicent from Polytechnic University in
Valencia, Spain and M.C. Pretorius,from Citrus Research
International in Nelspruit, South Africa, and hosted by
Collison Brentu of the University of Ghana. Collison
is a Ph.D. student working on citrus black spot at the
University of Ghana under the direction of Professor K.
Oduro and Pete Timmer, and he is a Research Officer
at the experiment station in Kade. Surprisingly, Ghana
has about 60,000 ha of commercial citrus primarily for
domestic consumption, but they export some organic

on black spot and
for us to become familiar with the Pseudocercospora
problem"said Dr.Timmer. Pseudocercospora isa disease
that is limited to Africa, but has been spreading south
and west and affecting citrus production throughout
that area. The disease produces large lesions on the
fruit and leaves and causes significant fruit drop prior
to harvest. Some research has been conducted on the
disease in Kenya and Cameroon. In addition, M.C. did
his M.S. thesis on the problem in Zimbabwe. He is one
of the few active researchers who are knowledgeable
about the disease. Pseudocercospora would be a
serious problem in Florida and any other humid citrus
area. Antonio has quarantine facilities in Spain where
at least some laboratory and greenhouse work can be
conducted in addition to field studies in Ghana and
Dr. Dewdney concluded, "With the importance of
introduced diseases in Florida such as greening and
canker, it is important for us to be knowledgeable
about other potential threats to the industry."



Drs. Natalia Peres (GCREC-Balm) and Pete Timmer
organized a one-day workshop on Colletotrichum
Diseases of Fruit Crops prior to the meeting of the
International Organization of Plant Pathologists in
Torino, Italy held on August 24 2008. The meeting
dealt with species, populations, and control of these
important fungal pathogens on many crops such as
citrus, strawberry, apple, grapes, olives, almonds, and

As in years past, the CREC Annual Staff Meeting
was held prior to the 2008 Holiday Party. Each year,
an employee is awarded the honor of "Employee of
the Year" in one of three categories (administrative/
clerical, technical, and trades). As stated by Dr.
Browning, Employees of the Year for 2008 were Ms.
Shelby Graham (Director's Office) in the administrative/
clerical category and Ms. Turksen Shilts (Dawson Lab)
in the technical category. Congratulations to both.
In addition to the employee awards, Dale Price,
Human Resources Dept., thoroughly reviewed the
years of continuous service of CREC employees so
they too may be honored for their years of service
to the University and CREC. This year 15 employees
were honored ranging from five years to 35 years of
continuous service:

Posters and Pastries

Research Gallery Returns to CREC

November 25, 2008 marked the return of"Posters and Pastries."This event in the past was held each year to give
both postdocs and graduate students an opportunity to showcase their research for the CREC and Citrus Industry
Communities, as well as to each other. Participation in the November event included 17 postdocs and 21 graduate
students representing all working groups at CREC. Their work showed a good working knowledge of the research
studied, creativity and great presentation of the subject matter. All students, faculty advisors and postdocs were
invited to a luncheon immediately following the two-hour event.
In an effort to continue to improve Posters and Pastries 2009, some guidelines will be implemented for a more
uniform presentation. As with many conferences, posters will be of specific dimensions and a small identifying
photo of the student, postdoc, or presenter will be required. An additional suggestion was to create an award and
guidelines for the best poster in technical and creative categories. Many suggestions have been offered to the
committee, and if you wish to share any suggestions to help improve Posters and Pastries, please feel free to email
Kathy Snyder at snyderkm@ufl.edu. Congratulations to all our participants for a job well done.

Dr. Qamar Zaman worked at CREC as a postdoc in
precision agriculture from 2002 to 2005. His research
was supervised by Drs. Masoud Salyani and Arnold
Schumann in 2002 and then under the supervision
of Schumann from 2003 to 2005. While working at
CREC, Dr. Zaman's research focused on ultrasonic
tree measurement methods, variable rate fertilization
and electromagnetic induction techniques for soil
Dr. Zaman left CREC after accepting a position
as a postdoc at Tokyo University of Agriculture and
Technology, Japan. In December 2006, he accepted
a position as an assistant professor and machinery

Dr. Russell Rouseff, University
of Florida/Institute of Food and
Agricultural Sciences (UF/IFAS) Citrus
Research and Education Center
(CREC), Professor of Food Science
and Human Nutrition, specializing
in food chemistry, is the 2009 winner
of the Advancement of Application
of Agricultural and Food Chemistry
Award from the American Chemical
Society, ACS.
The Award, which was
established in 1971, was created
to recognize and encourage
outstanding contributions to pure
and/or applied agricultural and
food chemistry. The Division of
Agricultural and Food Chemistry of
the ACS administer the award and it
is sponsored by International Flavors
and Fragrances, Inc.
The rules of eligibility are clear:
a nominee must have made (1) ru
outstanding application of chemistry
and/or chemical technology to the
solution of agricultural or food problems of importance
to the nourishment and health of mankind, or (2)
outstanding contributions to the advancement of pure
and/or applied agricultural and food chemistry.
Rouseff's nomination for the award received full
support from Dr. Harold W. Browning.
"As Center Director for the UF, IFAS Citrus Research
and Education Center, and Coordinator for UF
Citrus Research, I am familiar with the outstanding
accomplishments that Dr. Rouseff has achieved in the
area of flavor chemistry of processed fruit products.This
area of research has implications for advancing citrus
products as wholesome, nutritious and desirable in the
American diet.
Dr. Rouseff's work has lead to an increased
understanding of flavor components and their
differential expression in juices of different citrus

ssell I

varieties. This work has revealed
previously unknown compounds
present in low quantities in
processed juices that contribute
both positively and negatively to
juice quality and flavor. Discovery
of the varying origins of these
compounds in fruit and as by-
products of processing allows for
their use in diagnosis of processing
abuse and improper storage,' said
Browning continued, "In
addition to application of
chemistry to flavor and aroma
of processed citrus and other
fruits, Dr. Rouseff has directed his
expertise to a team effort focused
in an entirely different area. Florida
citrus and other regions of the
world are being challenged by a
bacterial disease (Citrus Greening)
vectored by the Asian citrus
psyllid. This insect is ubiquitous
in Florida, and is an extremely
difficult target for integrated pest management.
Through collaboration with a UF entomologist, Dr.
Rouseff has identified a number of compounds that
promise an entirely new approach to managing
citrus greening through modifying the insect vector
behavior, and thus could be an extremely important
discovery. Collaborations and opportunities such as
this often arise from interdisciplinary groups sharing
a vision, and the quality of Dr. Rouseff's analytic
chemistry has made this new collaboration possible,
well beyond the scope of his ongoing fruit flavor and
aroma chemistry."
Dr. Rouseff will receive $3,000, an engraved plaque,
and an allowance to cover the traveling expenses to
the meeting at which the Award will be presented.

Drs. Megh Singh, Ron Brlansky, and Michael Rogers
traveled to India to see how India is coping with HLB
(citrus greening disease). This disease has been in
India for nearly 100 years and they are still producing
citrus. India is the second largest producer of citrus
after China, with a production of 44.04 million tonnes
of fruits from an area of 3.72 million hectares. While
sightseeing in India, Drs. Brlansky and Rogers grabbed
the nearest taxi to a trip to a fort at the top of the hill in
the city of Jaipur. Little did they realize that only taxis
available were elephants.


In October, 2008, a group from CREC: Pedro
Gonzalez, Dennys Cornelio, Wije Bandaranayake,
Robert Spitaleri, and two visitors from Brazil, Andre
Giorgetti and Andre Da Silva, went on a fishing trip
in the Gulf of Mexico. The charter, Blue Dolphin, took
them 30 miles offshore from Tarpon Springs, Fla.The
Brazilian visitors, who worked at CREC for 3 months,
wanted to try fishing in the Gulf.The catch for the day
was about 100 pounds of fish. A good time was had
by all and the group recommends the experience to
