This Fall like many fruit prices are on the top of most growers minds. The crop forecasts so far have been fa-
vorable on the yield side, which is not as favorable on the price side. It is obvious that citrus growers are go-
ing to need to make more money for their fruit in order to increase grove management for pest and disease
pressures. I originally wrote in this column how we were fortunate as HLB infection levels in the northern re-
gion have been low. I erased what I wrote just two weeks ago as it is becoming more apparent to me that we
have a larger % infection level than I think most growers realize. As greening symptoms have becoming ap-
parent the last few weeks, quickly growers that are looking for HLB are finding it. There are many opinions
on what to do with HLB infected groves within the state and throughout the world however, there is one activ-
ity that everyone agrees upon, psyllid control is a must. If you have not been serious about controlling your
psyllid populations (and by serious I mean spraying at least 5-6 times a year) I encourage you to start before it
is too late. It is my opinion that growers who choose to do nothing will not be in the citrus business in 5 years.

Mid Florida Citrus Foundation Update
As many of you know I am active participate in the management of the Mid Florida Citrus Foun-
dation (MFCF) A.H. Krezdorn grove. As part of the management team I work very closely with
the grove operations. This experience is very beneficial in my opinion, as it helps me relate to
grower problems and issues. Over the past two years we have been surveying the MFCF grove
for HLB and canker. Our first HLB find was approximately 1.5 years ago; we had three trees
found to be HLB positive. We immediately removed those trees. At the time we had a few trees
with "unusual" symptoms but were found to be PCR negative. We decide to keep those trees.
We surveyed 5 months later and found a handful of HLB infected trees, which we again removed.
During this period of time I would classify our psyllid control efforts as marginal.
A psyllid spray program has consisted of a dormant spray for the last 2 years, plus 2 to 3 psyllid
control sprays as needed. Many blocks have had psyllid research work applied to them. Most
of the time this has meant untreated checks, areas within these block with no psyllid control.
Other blocks without psyllid trials received sprays sporadically throughout the year when we
had access to spray equipment. Overall the psyllid control was not great.
Fast forward to this week (as I am writing this) our latest survey has produced 797 visual con-
firmed HLB trees. To say I am shell shocked would be an understatement. These developments
have surprised me. What has caused this rapid infestation? I think a combination of poor sur-
veying results early on and a lack of a really good psyllid control program.
To add insult to injury we also identified 28 canker infected young Navel trees. Just this past
year we added windbreaks around and between a 40 acre section of grove. We had plans
(depending on funding) to add windbreaks around every block. These plans include dissecting
larger blocks into smaller blocks surrounded by windbreaks. Due to the small number of trees
infected we will try to defoliate these trees in an attempted to minimize the inoculum source.
This block currently does not have windbreaks however we are planning to put them in place as
soon as possible.
One of the challenges of managing production at the MFCF has always been funding. Many
times research is a costly endeavor. Many areas of the grove are growing unprofitable fruit, yet
still require grove care. Also, in recent years we have grown off many young trees. Now comes
increases in cost for greening and canker management adding to the already tough task. It
gives me a great appreciation for grower's plight during these difficult times.
The type of intensive management that is required to grow citrus with canker and greening is
expensive. Citrus fruit returns must improve in order for growers to manage these diseases. It
is in the best interest of the entire industry (growers, buyers, processors, packers) to maker
sure that growers can afford to give their groves the necessary inputs that current conditions re-
Area Wide Spray Dates Week of October 19th
I had been asked by my Advisory Committee to pursue an effort for area wide psyllid control
program for Central Florida. I have attempted to coordinate this effort a number of times over
the past year. Unfortunately I have been unsuccessful. The coordination of this event is a mas-
sive amount of work, if trying to contact all growers via phone. I believe that if we are to be suc-
cessful in this effort, it will take everyone that is willing to become an active promoter of this
idea. If you would like to learn more about why area wide spray programs for psyllid control is a
good idea please see Drs. Hall and Stansly's presentation at Citrus Expo: http://
As far as my coordination attempt, here is what I have found out so far. Aerial application in our
area is not practical. There are many issues as to why, but the main one comes down to money.
It actually is cheaper to use ground applied low volume technology, as the flight distances make
aerial prohibitively expensive. Low volume technology for psyllid control is relatively inexpen-
sive, effective and can cover larger acreages. If you want to learn more about low volume tech-
nology and its effectiveness for psyllid control please see Drs. Stelinski, Rogers, and Stansly's
presentation at Citrus Expo: http://www.crec.ifas.ufl.edu/extension/greening/misc/
Stelinski.html For even greater details on low volume technology please plan on coming to the
October 1st program at the Lake County Agricultural Center in Tavares. Don't forget to register
352-343-4101. If you have more traditional equipment and want to use it for this area wide effort,
of course that will work as well.
I have already contacted a number of growers concerning an area wide program and most have
said they are interested. Most already spray for psyllids and it really is just an issue of all grow-
ers trying to time a spray for a similar date. I am suggesting that growers work together to do
activities that you normally would do, just do them in a unified effort, that is spray for Asian citrus
psyllid control sometime within the same week. Here is what I have proposed with the help of
Dr. Michael Rogers for an area wide spray effort. We are suggesting starting off with at least two
sprays. The first one is to be conducted the week of October 19th. The second spray we recom-
mend the week of January 25th, 2010. The second spray would be considered the dormant appli-
cation. Obviously weather plays a big role in the ability of application timing, thus why we have
designated a week for application. It would be great to call your neighbor and talk to them
about spraying at the same time!

Sign-up Now for Conservation Assistance On Your Farm
The U.S. Department of Agriculture's Natural Resources Conservation Service (NRCS) in Florida
has set a cutoff date of October 30, 2009, to submit applications for several voluntary conserva-
tion programs that may help eligible participants pay for conservation practices to prevent soil
erosion, improve water quality, restore wetlands and provide habitat for wildlife. The Environ-
mental Quality Incentives Program (EQIP) is a conservation program that provides financial and
technical assistance to farmers and ranchers who face threats to soil, water, air, and related natu-
ral resources on their land. Through EQIP, NRCS develops contracts with agricultural producers
to voluntarily implement conservation practices to address environmental natural resource
problems. Persons engaged in livestock or agricultural production and owners of non-industrial
private forestland are eligible for the program. Eligible land includes cropland, rangeland, pas-
tureland, private non-industrial forestland, and other farm or ranch lands.
NRCS encourages interested parties to visit with their staff as soon as possible. Applicants who
apply early have more time to resolve any program or land eligibility issues. For more informa-
tion on conservation assistance contact your local NRCS Field Office listed in the telephone di-
rectory under "U. S. Government" or www.fl.nrcs.usda.gov/contact/index USDA is an equal op-
portunity provider and employer. www.fl.nrcs.usda.gov/programs/
NOTE: Although applications are accepted on a continuous basis, Florida NRCS has estab-
lished cut-off date of October 30, 2009 for evaluation and ranking of eligible applications
for the 2010 program year.

Weather Watch Program
Well hard to believe that we need to be thinking of cold weather already. However sign up has
begun for our Weather Watch Program. We had over seventy agricultural producers participate
last year. Why should you sign up? Weather Watch employees a consultant with over 45 years
agricultural weather forecasting. In addition the service attempts to educate growers on how to
utilize weather data to make cold protection decisions. This service attempts to save two pre-
cious resources; water and money. Please encourage anyone that you think is interested in the
service to sign up by November 16th, which is when we will start the service. This year late reg-
istration will cost double the usually sign up fee.
This year there are some improvements to the service. We now have an 800 number which al-
lows for toll free access if you live out of the 352 area code. This year we will not be utilizing the
Nextel walkie talkie feature as many growers no longer have that service. Instead we will have a
toll free conference number in which 125 individuals can participate at the same time. I am ex-
cite to have the ability for all of us to communicate at one time during a freeze event, I believe
this will be an upgrade. Last year we implemented an email notification which many growers
appreciated, we will continue to utilize this service. I always appreciate feedback, let me know
anyway that I can improve this service! There is a sign up sheet attached to this newsletter.
USDA Commercial Citrus Inventory
If you have not heard, the USDA has now begun surveying citrus acreage annually. Below is a
table I put together with my counties and percent change in acreage from 2008 to 2009. Brevard
had the biggest loss of citrus acreage with 23%, while Osceola gained 6%. Overall the state lost
1% of its citrus acreage. I personally know of a few new groves being replanted this year,
mostly has a result of increased pressure for local property appraisers on "abandoned citrus
groves". That coupled with the dramatic decrease in development, I expect that we will defi-
nitely see acreages holding stead and maybe even increasing for the 2010 inventory.

Recent Extension Activities: Low Volume Rodeo, Small Farms Conference & Expo
The extension service, Florida production re-
search advisory council and the USDA/ARS re-
cently held a low volume equipment rodeo for
citrus growers. We had thirty-two machines
evaluated for particle size distribution. Pic-
tured upper left is a low volume machine being
evaluated by Dr. Clint Hoffman. The green is a
protective wrap that protects the laser device.
The laser measures 40,000 particles in a matter
of seconds. The results are then printed off a
computer located in picture to the lower left.
Growers were given there print outs to main-
tain for their record keeping.
The first annual statewide small farms confer-
ence started off with a bang. Over 800 atten-
--- dees learned about new crops, organic produc-
tion and marketing. The meals contained all
locally grown produce from small farms from
around the state. Everyone who I spoke to said
that the conference had a great energy to it.
