First Highlands Citrus Talk Newsletter Totally E-Mail
This is the first edition of the "Highlands Citrus E-Talk Newsletter" to go out totally via e-mail. There will
not be a surface mail edition going out except to those who have responded to me that they either cannot
receive e-mail or they would prefer to only receive a surface mail version.
This will allow me to continue this newsletter with only a miniscule postage budget.
Thank you for your cooperation

Citrus Low Volume Technology
What is it? In the Low Volume Technology workshop presented here in March, several speakers
pointed out that the correct term for the low volume application technology that we wish to use to
combat psyllids and other citrus pests is "Low Volume Application/Misting". These sprays are
applied at greater than 100 micron particle size, with volumes as low as 2 gallons per acre. This
"misting" technology allows the pesticide to move at low volumes through the air into the citrus
tree canopy and landing on citrus tree surfaces where it can contact or be picked up and kill the
psyllid. The spray movement is limited and confined to where one finds psyllids in or on citrus
trees. Fogging (sprays less than 100 micron particle size) tend to move longer distances and may
not effectively enter the canopy of a citrus tree, rather moving around or over it. The fogging
spray is intended to move the pesticide further distances over larger areas where drift is desired
in such applications as mosquito control. This "drift" could carry the pesticide to unwanted areas
beyond the grove.
What is needed? To accommodate the use of pesticides to manage citrus psyllids at rates as
low as 2 gallons per acre, almost all labeled pesticides effective in managing the citrus psyllid
would require a label change. Pesticide manufacturers have been diligently working over the past
few months to get low volume rates on their pesticide label.
Where could Low Volume Pesticide Applications be used? Low Volume Pesticide
applications can be made using smaller spray equipment carried through the grove at higher
speeds allowing more area coverage, in less time, at a lower volume, and less cost. With the re-
colonization of psyllids in areas adjacent to groves after a grove spray application resulting re-
infestation of the grove in border areas one could re-spray borders effectively in a shorter period
of time at a lower cost and hence delaying another "total grove" spray. Also, a grower could
spray areas more frequently, where more citrus greening has been found and symptomatic trees
removed (hot spots). This would lessen the chance that the bacteria could be acquired and
transmitted by psyllids from non symptomatic HLB positive trees that may remain in the area.
What Pesticides can now be used low volume? Department of Agriculture, "Special Local
Need", 24 or similar labels have been granted for several products including Sevin, Malathion,
Danitol 2.4 EC, Delegate WG, dimethoate, and petroleum oil, in a minimum of 2.0 gallons per
acre of finished spray (low volume mist). The label on the product may not have this current rate
technology on it yet so it is MANDITORY that the applicator has an updated label in their
possession before making the application. Current supplemental labels can be obtained from the
manufactures and distribution representatives or many can be obtained on-line form the
manufacturers web site. BE SURE and read the label and follow all recommendations and
Other New Citrus Pesticide Labels

Restricted Use Pesticide CEU's
Frequently people will call me in a bind that their Restricted Use Pesticide (RUP) License is due
for renewal and they do not have enough CEU's in the CORE or a Category.
CORE CEU Opportunities
4 CORE CEU's are required in CORE for license renewal. Generally there are fewer workshops,
etc. that offer RUP CEU's in the CORE Category. The specific category CEU requirements vary. I
have prepared a Fact Sheet to help you in finding opportunities to gain CEU's in both CORE and
There are now two relatively easy ways to get CORE CEU"s in a self study manner.
1. First is with the FNGLA Magazine "Ornamental Outlook". To gain CORE CEU's go to the
"Ornamental Outlook Magazine Web Site: http://www.ornamentaloutlook.com, and follow
2. Go to the Citrus Extension Agents Web Site: http://citrusagents.ifas.ufl.edu/, and follow
Category CEU Training Opportunities
The number of CEU's required and the subject matter differs for each of the RUP Categories.
There are, however; more training opportunities to get Category CEU's. To identify what training
opportunities are available go to the FDACS AES Web Site: http://flaes.org, and follow the
Attached to this newsletter is a Fact Sheet "CEU Opportunities Fact Sheet" which gives you
details on how to use each of the web sites.

Ridge Citrus BMP Compliance
Kevin Hancock, Senior Engineer, at the Indian River REC is working with the IFAS Best Management
Practices compliance to be sure that everyone has filed their "Notice of Intent" (NOI) to comply with the
Best Management Practices (BMP's). With Highlands County covering two Water Management Districts
and several BMP Practices, Kevin is contacting growers to help them be sure they have covered all of
their bases and that their NOl's are correct.
If Kevin contacts you give him a few minutes of your time and you will know you have all of your "BMP
Ducks in the right row".
FDOC's New Web Site
FDOC has a new web site that you may want to place in your "favorites". It is at
http://www.fdocqrower.com/. You can contact them at: info(fdocqrower.com.
They also are producing a newsletter focusing on the status of canker and greening research. The
newsletter is titled "CITRUS DISEASE RESEARCH". If you would like to be placed on the mailing list to
receive this newsletter periodically contact: email@example.com.
