Hurricane Preparedness Checklist
Now that we are past the driest 6 months in parts of Florida since rainfall records have been
kept, it's time to start thinking about removing excess water and preparing for the possibility
that another hurricane will draw a bead on the Florida peninsula. Dr. Bob Rouse, SWFREC,
published an EDIS Fact Sheet in 2001 entitled Hurricane Preparedness for Citrus Groves. He
reviewed the publication in 2008 after we suffered the hurricanes in 2004-2006. Although
many of you have developed first class action plans for dealing with a hurricane, it couldn't hurt
to read EDIS publication HS 804 and see if your hurricane plan covers all the bases.

Quick Reference Guide to Citrus Insecticides and Miticides
This handy publication (ENY- 854) in chart form underwent another revision in May of 2009 that
reflects several changes of the pesticides that are registered for use on Florida Citrus. I have a
number of laminated copies at my office for distribution or you can click on the following
hyperlink and save it as you wish.

2009 Citrus Expo
This year's Citrus Expo will feature the theme "Using Today's Innovations Toward Future
Success". The Expo will be held at the Lee Civic Center in Ft. Myers on August 19-20, 2009.
Pre-Registering for the event will enter you in a grand prize drawing and help the organizers to
plan for your complimentary meal tickets. The program features pest management, production
economics, mechanical harvesting, current research and Good Agricultural Practices (GAPs)
topics. There will be CEU and CCA credits offered for appropriate portions of the program on
both days. In addition, the Citrus Expo boasts the citrus industry's largest trade show with
more than 150 exhibiting companies on display.

Notes on Wide Area Psyllid Spraying
Our recent Citrus Canker and Greening Seminar, which featured 5 researchers from the
SWFREC in Immokalee, was very well attended by local growers. Dr. Phil Stansly, entomologist,
made a very informative presentation regarding Asian Citrus Psyllid management. The
essentials of the spray program he recommends for mature trees are area wide applications of
broad spectrum insecticides directed at adults during the dormant season, and additional
applications as needed during the growing season, preferably with selective materials and when
there is a minimum of flush. The dormant sprays can be initiated anytime after fall flush and
terminated before spring bud break. The objective is to reduce overwintering psyllid
populations to the lowest possible level, and thus reduce the numbers of psyllids multiplying in
the spring flush and their subsequent dispersal immediately thereafter when the greatest
spread of HLB (Citrus Greening Disease) is likely to occur. This strategy has been shown to
provide the most optimal psyllid control with the least possible impact on beneficial.

Just as the most effective sprays are made during dormant season, their effectiveness is
multiplied if they are applied area wide. He showed in his presentation how some 80,000 acres
in SW Florida were sprayed this winter by air between Dec. and Jan. with excellent results.
Next season they are planning 2 area wide dormant sprays, one after fall flush before Christmas
(Nov., Dec. and one afterwards before bud break (Jan. to early Feb.).
Dr. Stansly mentioned that their studies have shown that, while psyllids readily move out of
spring flush and away from abandoned groves, they have observed little movement at other
times between sprayed and unsprayed plots that are otherwise identical. In other words,
psyllids won't necessarily move into a neighboring block just because it has been sprayed.

This supports the idea that, during the growing season, psyllids can be managed on a block by
block basis. The key is good psyllid scouting to track populations and respond to significant
increases with sprays when needed. He said that the "tap" method of monitoring adult psyllids
has given consistently reliable results. He highly recommended that growers and consultants
monitor all blocks populations on a regular basis: every two weeks during warm weather and at
lengthening intervals of 3 to 4 weeks as weather cools and the psyllid life cycle slows down.
More information on psyllid scouting and management is available on their website at
http://www.imok.ufl.edu/entlab/. Dr. Stansly concluded by saying that beneficial are most
active during the growing season, especially when there is flush, and that negative impacts






from insecticides would be increased by area wide sprays applied at the wrong time. On the
other hand, area wide sprays will provide maximum benefit during the dormant season when
psyllids are most vulnerable and beneficial least exposed to collateral damage from
insecticides.


Agribusiness Management Degree at UF/IRREC
University of Florida Agribusiness Management degrees provide graduates with a very strong
credential in a promising career, as agriculture remains the state's second ranking industry.
Recent graduates who earned Bachelor of Science degrees in Agribusiness Management at the
Fort Pierce location, the UF/IFAS Indian River Research and Education Center, now hold
prominent positions with organizations such as the UF/IFAS St. Lucie Cooperative Extension,
Indian River State College, Syngenta Crop Protection and privately owned citrus management
and production firms. Starting salaries range from $35,000 to $40,000.

An Agribusiness Management degree will satisfy a very wide range of career interests all along
the Treasure Coast. Such a degree could provide an exemplary background for those seeking
management positions with the large grocery retailers, one of the most secure employment
prospects. Those who wish to start a business of their own would hold the knowledge and
resources to be successful in a region that supplies the rest of the nation with yearlong food
and plant products.

Courses in business management, human resources, and finance are part of a rigorous
curriculum offered by the state's most prestigious educational institution-the University of
Florida. As competition to enter the University of Florida Gainesville campus becomes
increasingly competitive, the UF campus in Fort Pierce has enrollment spaces available now for
fall semester 2009.

Jane Bachelor, who holds an MBA, and is a lecturer and marketing coordinator at the UF center,
is offering two courses in the fall which support the Agribusiness Management degree program
and the professional development certificate program. Principles of Agribusiness
Management provides participants with general business management and leadership skills.
Advanced Agribusiness Management further develops those skills as course participants
create business plans for their own actual or anticipated future businesses.
Scholarships from the Bud Adams Family, the Bryan Schirard Memorial, the Treasure Coast
Gator Club, the Garden Club of Indian River County and the University of Florida College of
Agricultural and Life Sciences are available to eligible applicants. For information about UF/IFAS
degree and course offerings at the UF Indian River Research and Education Center, please

mail: ikwhite(ufl.edu

Actara Citrus Label Addition
Syngenta Crop Protection has announced the addition of all citrus varieties, bearing and
nonbearing, to their Actara broad spectrum insecticide label. Actara is labeled for control of
Citrus Psyllids, Leafminer, Scale Insects, Root Weevils and other insects. The active ingredient
is thiamethoxam, a second generation neonicitinoid which gives citrus growers an additional
mode of action to manage citrus insect pests. Contact your pesticide supplier or Syngenta
representative for additional information.

Just for Fun
Farmer Nugene walked into the bar, sat down and put his legless dog on the stool next to him.
The barkeep poured a beer for Nugene, and then, to make conversation, asked the dog's name.
"He don't have a name," replied Nugene.
The barkeep, not sure if he heard him right, asked again, "Come on, Nugene, what's his
name?" "Every dog has a name!"
"Not this dog," drawled Nugene. "What good is a name? Can't come when I call him."
