Control of Citrus Psyllid and Citrus Greening -
A Word of Caution
It seems that rarely a day goes by that I do not have a discussion with someone regard-
ing the Control of the Citrus Psyllid and Citrus Greening. Without a doubt the two are
tied tightly together. Control or management of the psyllid and greening go hand in
Some times growers want to discuss with me the use of pesticides in non-traditional
ways or using chemicals that are not traditionally used to manage or control citrus pests.
Some people have described our current battle with psyllids and greening as a war and
require a war mentality. This is a good approach to our winning this war with greening;
however in the process we still need to be cautious in the weapons we use and how we

Highlands County Citrus Extension "E-Newsletter"
I am in the process of introducing a new method of communicating with citrus growers and others, utilizing the computer,
in a more timely way. The tile of my new communication tool is "Highlands County Citrus E-Talk". I will continue this
newsletter via standard mail, but I will also send it electronically to any citrus grower, manager, or allied industry repre-
sentative. I will send it to anyone who has given me their email address. This will also include meeting
announcement and reminders, timely information releases, etc.
If you have not already and wish to receive this information via your email, just send me a
message at plowboy)ufl.edu and I'll put you on the list.

Citrus Grower Tools
As I have mentioned before as a "new guy" at this game, I want to be sure that growers
know what "Tools" that are available for use. In today's world we all are becoming aware of V
the many uses we have of computers. One of the most dynamic uses is the access of
In the arena of the local Highlands County Extension Service there are several tools that
are available that can be of use to you.
Highlands County Extension Web Site
This web site at http://highlands.ifas.ufl.edu was developed and is managed right here in Highlands County.
It contains a wealth of information and the links to more information.
On this site you will find copies of this and other newsletters. You will find local extension citrus meeting an-
nouncements, registration information, etc. This site will link you to the IFAS EDIS site, http://edis.ifas.ufl.edu/,
and the IFAS Solutions for Life site http://solutionsforyourlife.com, where you can obtain a plethora of informa-
tion on citrus and all of agriculture.
On the "Citrus Page" you will find citrus extension newsletters, citrus program announcements, and access to
information on Canker and Greening, and links to other sites related to citrus.
I will continue to add to this web site more "tools" that should be helpful to you. If you have suggestions for addi-
tions for this site, let me know.
Florida Citrus Extension Web Site
This web site at http://citrusagents.ifas.ufl.edu is a new site which has been developed to help you the grower to
access information around the citrus industry. The plan is for you to be able to read their citrus newsletters,
learn about the meetings that they have planned, and have access to information throughout the citrus industry.
Florida State Horticultural Society
The Florida State Horticultural Society will hold its annual meeting June 1 4, 2008 at the Ft. Lauderdale Marriott
North. Presentations this year will include greening and canker control, psyllid management, mechanical harvesting,
weather data management decision making and general horticultural practices.
This year the Chairman of the FSHS Board is Peter McClure, the President of FSHS is Dr. Jim Syvertsen, and the
Citrus Sectional Vice President is Dr. Kelly Morgan
The FSHS meetings are an ideal place to hear current research findings and also to network with the people doing
the research. I would encourage you to attend. For registration information go to www.fshs.org and for Program In-
formation you can contact Dr. Eric Simone at (352) 392-1928, Ext. 208
Florida Citrus Production Research Advisory Council
The FCPRAC also known as the "Grower Box Tax Committee" has since 1991 been the group that has managed
monies collected from citrus growers in a per box tax to fund citrus research. In recent months the council has be-
come the mechanism whereby funding from other sources (state and federal) have been funneled to support citrus
research, especially research directed at citrus greening, citrus canker and the citrus psyllid.
The council is made up of fourteen growers of which, Bill Barber, Bert Harris, and Steve Farr are from this area. The
council's coordinator is Dr. Steve Rogers and their Secretary is Marshall Wiseheart who works for FDACS. Peter
McClure has recently been re-elected as chairman and Bill Barber as Vice Chairman.
Since my return here to extension, I have sat in on the FCPRAC meetings and it has been my observation that this
council has done a yeoman's job in evaluating research proposals and directing funds to research. This all volunteer
group has spent insurmountable time in completing their responsibilities in behalf of the citrus Industry. This past
year they have overseen the direction of about $7 million targeted primarily at citrus greening and psyllid manage-
ment and control. This coming year they are working at ramping up yet more in research and funding.
The council members are committed to getting the job done and keeping everyone informed. You can get more in-
formation on the Council, and its work, current research findings, etc at their web site www.fcpracs.com. You should
go to the site, and register for a Username and Password. You can then access all of the current information about
what research is being done, and what new information is being released, as well as how the funds are being spent.
I want to personally thank Dr. Rogers and the Council for the job they have done and are now doing. I would encour-
age you to do also.
