FSHS Annual Meeting
The 2009 Florida State Horticultural Society
Annual Meeting is scheduled to be held
June 7-9, 2009 at the Windham Riverwalk
Hotel in Jacksonville. This meeting will
feature both scientific and less formal
presentations regarding citrus, vegetable
production, subtropical fruits and landscape
and ornamental plants. The sessions for the
various disciplines are held concurrently so
you can focus on the horticultural crops that
interest you. In addition, the meeting offers
a great opportunity to meet with researchers
and other resource individuals in a relaxed
atmosphere without an appointment!
Become a member of the FSHS and join
your fellow horticulturists in Jacksonville.
Another New Citrus Pest
It's not your imagination that we're hearing
about and seeing new intruders on a more
frequent basis. The Sri Lankan Weevil has
been in Southeast Florida for a while and is
rapidly becoming more of a problem. It
looks very similar to the familiar Little Leaf
Notcher Weevil but seems to have a more
varied appetite, which of course, includes
your citrus trees. In fact, another common
name for the insect is Yellow-headed

IPM, Pest Scouting and Asian Citrus Psyllid
Powerpoint Presentations on the SWFREC Website
Dr. Phil Stansly, entomologist at the Southwest Florida REC in Immokalee has a couple of
very informative PowerPoint presentations posted on the SWFREC website. Of particular
interest are the presentations entitled "Scouting Citrus for Pests" and "Integrated
Management of Asian Citrus Psyllid". While we are all focusing so much attention on ACP
populations, it is important to remember that the old citrus pests are still out there. In
addition, an unwanted result of our control efforts for ACP has been the appearance of some
of the old scale insect pests that we haven't had to deal with for a while. Click on the

Pesticide Recordkeeping Requirements
Now that we are well into the 2009 citrus spray season, I thought it would be timely to review
the current pesticide recordkeeping requirements as mandated by the Florida Pesticide Law.
The Florida Department of Agriculture and Consumer Services (FDACS), under the authority
of the Florida Pesticide Law, requires certified pesticide applicators to maintain records
relating to the application of all restricted-use pesticides.
These pesticide application records are unrelated to, and are in addition to, the Worker
Protection Standard requirements that notice-of-application information be conveyed to
agricultural workers and pesticide handlers for all pesticide applications.
The restricted-use pesticide application records require that ten primary data elements be
kept on record for each restricted-use pesticide application. These include:
1. The name and the pesticide applicator license number of the licensee responsible for
the pesticide application:
2. The name of the person who actually applied the pesticide;
3. The date and start time and end time of treatment;
4. The location of the treatment site, which may be recorded using any of the following
County, range, township and section;
An identification system utilizing maps and/or written descriptions that
accurately identify the location of the treatment and distinguish the treatment
site from other sites;
The identification system establish the USDA found in 7 CFR 110, which
utilizes maps and numbering systems to identify field location;
Global Positioning System (GPS) coordinates or longitude/latitude points that
delineate the treated area; or,
The legal property description.
5. The crop, commodity, or type of target site treated;
6. The total size (in acres, square feet, acre-feet, number of animals treated, or other
appropriate units) of the treatment site;
7. The brand name and EPA registration number of the pesticide product applied;
8. The total amount (Ibs., gal., etc.) of formulated product applied; (not the gallons of
finished spray applied);
9. The application method; and,
10. The name of the person requesting or authorizing the application, or a statement of
authority to make such application if the application was made to property not owned
or leased by the licensee.
Commercial applicators must, within thirty (30) days of the application of a restricted-use
pesticide, provide a copy of the application record to the person for whom the application was
The required information shall be recorded no later than two (2) working days after the date
of application, and may be incorporated into other business transaction records. All records
must be retained for a period of two (2) years, and must be maintained in a manner that is
accessible to authorized representatives (FDACS Inspectors).
Any recordkeeping form is acceptable as long as the required data are included. This allows
applicators flexibility to fit the recordkeeping requirement into their current recordkeeping
The bottom line for pesticide applicators is:
The Worker Protection Standard (WPS) requires that records for ALL pesticide
applications must be made available to agricultural workers and pesticide handlers at
a central location until the applicable restricted-entry intervals have expired.
FDACS requires that records of all applications of Restricted Use Pesticides be
maintained for a period of 2 years after those applications.

Label Updates for Low Volume Mist Applications
There have been a number of recent label changes to allow low volume mist applications
of pesticides for Asian Citrus Psyllid control. As a result of those changes, dimethoate,
Sevin, petroleum oil, malathion and Danitol may be applied at rates as low as 2 gallons
per acre of finished spray (mist). It is hoped that by June 1, 2009, Mustang, Delegate and
Micromite will also have been granted 24(c) labels for low volume mist applications.
Low volume mist applications at a minimum of 2 gallons per acre should be differentiated
from fogging applications such as those used in mosquito control. Mist applicators should
be engineered and calibrated to generate particles with a median particle size of 100
microns. When used under proper weather conditions, mist equipment should deposit the
pesticide spray on the tree/psyllid and thus kill by contact. Fogging equipment generates
particle sizes that are much smaller than 100 microns, stay suspended in the air and thus
allow the targeted insects, usually mosquitoes, to fly into the pesticide particles.
IFAS researchers are currently working to establish the most effective working
characteristics of mist applicators and also to determine the most economical and efficient
application rates of the pesticides currently registered for use against the ACP. Early
reports are that the current pesticide materials registered for use against ACP are
effective when used in mist applicators.
Aerial Label for Clinch Fire Ant Bait
Syngenta Crop Protections, Inc. has received a Supplemental Label to allow the aerial
application of Clinch Fire Ant bait. As always, read the entire label to familiarize yourself with
any label restrictions that might be part of the label. Contact your agrichemical supplier for a
copy of the new label.
General Standards (Core) Pesticide Applicator Training
Preparation for the General Standards Exam required for all of the Certified Pesticide
Applicator Categories. 2 General Standard CEU's will be offered for individuals who are
current license holders (This includes Private Applicator and Ag Tree Crop). Ken Gioeli,
Natural Resources Agent will be offering this course on May 6, 2009 and then again on June
3, 2009. Pre-registration is required and the cost is $20. Call (772) 462-1660 for details
and to pre-register.
Aquatic Applicator Training and Exam

only and no Aquatic CEU's will be offered. Call (772) 462-1660 for details and registration
Agricultural Tree Crop Training and Exam
The Ag Tree Crop License category is for individuals who intend to apply or supervise
application of Restricted-Use pesticide materials on properties other than those owned by
their employer. These are generally contract applicators or people who work for
organizations that require more training to meet standards higher than required in the Private
Applicator Category. Comprehensive training and the exam will be offered on Thursday, May
14, 2009. 3 Ag Tree Crop or Private Applicator CEU's will be offered for current Ag Tree
Crop and Private Applicator license holders. Cost is $15 and pre-registration is required.

Just for Fun
While on a trip to Detroit, Clyde wandered into the wrong neighborhood and was jumped by a
couple of muggers. He put up a tremendous fight, but eventually the thugs pinned him to the
sidewalk and searched his pockets. After all that effort, the bad guys only found forty-three
cents in change.
"Why in the devil did you put up such a fight for only forty-three cents?" shouted one of the
"Forty-three cents?" said Clyde. "I thought you were trying to get the $300 in my shoe."
A door-to-door vacuum cleaner salesman was driving past a farm in north Georgia when he
noticed a farmer lifting a large hog to the branch of an apple tree. He quickly pulled over and
saw the pig pluck an apple off the branch. The farmer put the animal on the ground and
picked up another pig to repeat the process. After the fifth hog, the salesman couldn't stand
it any longer and got out of his car and approached the farmer.
"Excuse me," he said, "but wouldn't it be a lot easier if you reached into the tree for the
apples and then gave them to the pigs?"
"I don't know," replied the farmer, reaching for another pig. "What would be the big
advantage to doin' that?"
"Well," said the salesman, trying to be polite. "For one thing, it would save a lot of time".
"Could be," said the farmer. "But then again, what's time to a hog?"
Here's hoping you get rained on,
