Dear Growers,


I would like to wish you a Merry Christmas and a Happy New Year! This past year has provided me the for-
tune of getting to meet and know many of you better. I feel blessed that I get to work with a great group of
people whom make my job very enjoyable. It is my desire to help you and the citrus industry in any way that I
can. Looking ahead at 2008, we all have a big challenge in combating citrus greening disease, but if we com-
bine our efforts as an industry I know we will prevail. Many research projects are being conducted, informa-
tion gleaned from these efforts will help to maximize production practices. Also, innovations from the grow-
ers themselves will continue to be disseminated and will contribute to the knowledge base that will allow us to
remain a competitive industry. I am excited about the year ahead and wish you all the best!

Some more thoughts on Greening


Greening of course is on everyone's minds these days. I have been challenged by some to think
"outside of the company line" concerning the promotion of grove surveying and removal of
symptomatic trees. They feel as if tree removal is not the answer and it only weakens the citrus
industry. The reason for recommending tree removal is to prevent the spread of the disease. In
instances where infection levels are low (which it is in Central Florida), I think this is a wise prac-
tice.

That being said, I recently took a field tour to South Florida with the other multi county extension
agents. I found the experience to be enlightening. Some of the groves in South Florida have 40-
65% infection rates and tree removal was being implemented. It is hard to justify removing half
of your trees per acre and maintaining the rest in a grove. It makes me realize that I should clar-
ify my advice on survey and removal. I believe survey and tree removal to be an important ac-
tivity in our area due to low infection levels. If infection levels rise to the point where a large
percentage of trees need to be removed then an alternate action would in my opinion be more
appropriate.

In conjunction with survey and removal of infected trees, should be a pesticide program for
psyllid control. Some area growers are having good success in suppressing the psyllid popula-
tion levels in their groves. Effectively controlling the vector of the disease is an important piece
to the greening challenge. The citrus growers that are actively controlling the psyllid, scouting
for the greening symptoms, and removing any inoculum are going to slow the spread and "buy
time" until we have more answers. Does that mean I am not for trying new or different ap-
proaches or ideas? No, I think where the disease is more established there exist the opportunity
to evaluate different production practices, in lieu of tree removal.

There are many questions that have yet to be answered, but I see many in our industry working
hard to find those answers. With these answers will come new and revised production practices.
I am encouraged by growers that continue to push ahead, try new things, learn from the mis-
takes, and refuse to wait for someone else to solve their problems. I am also encouraged by re-
searchers who are busily collecting data, evaluating data, and making conclusion from that data.
Through these efforts Florida citrus production will endure the presence of greening.











2007 Census of Agriculture


The U.S. Department of Agriculture's Na-
tional Agricultural Statistic Service (NASS) is
conducting a 2007 Census of Agriculture.
The Census takes place every five years, it
counts the nations farms and ranches and the
people who operate them. The Census looks
at land use and ownership, operator charac-
teristics, production practices, income and
expenditures and many other important is-
sues. The NASS Census provides information
that is used by federal, state and local gov-
ernments, extension agents, agribusinesses
and many other organizations. Census data
is used to make decisions about many things
that directly impact farmers. By responding
to the Census you demonstrate the value of
agriculture in the U.S. and your local commu-
nity. Participation in the Census is required
by law no matter how large or small your op-
eration. That same law protects the confi-
dentiality of all responses. The Census is to
be mailed out December 28th, 2007 and the
NASS is asking for replies by February 4th,
2008. The results of the Census will be pub-
lished in February 2009. For more informa-
tion about the NASS Census, visit
www.agcensus.usda.gov or call toll-free
(888) 424-7828. If you did not receive a cen-
sus Maggie has extra copies at our office.

Need Core CEU's?


I am often asked "How can I get more Core
CEU's (Continuing Educational Credit Unit) ?". I
try to apply for Pesticide Applicator CEU's for
my programs if possible. Most of the time the
topics do not cover "Core" subjects. There is an
easy way to obtain CEU's on-line. The Univer-
sity offers all types of CEU's at

http://pested.ifas.ufl.edu/onlinepesticideceus/

however these modules have a small fee associ-
ated with them. A free way to earn core CEU's is
on-line at

http://www.ornamentaloutlook.com/ceu/

There you will find an article series for each
month of the year. You can read the article and
submit an electronic question and answer form
to receive one Core CEU. When you click on
the link to receive your questions you will be
provided with contact information of who and
where to send the question and answers form.
The easiest way is to email, however you can fax
or mail the results. Articles are valid for up to
one year after they are released. That means
there is a possibility of twelve core CEUs to be
earned, more than enough to renew your li-
censes. Of course there also is our CEU DAY
held twice a year. This years will be June the
24th in Tavares and November 6th in Orlando,
see enclosed flyer for more details.

Greening Field Trip to South Florida

February 1st 7 A.M.-7 P.M.


As most are aware citrus greening disease is
much more prevalent in South Florida. Last
year we took a field trip to Highlands County to
look at greening and canker. This year we will
visit S.W. Florida. We will be leaving the Agri-
cultural Center in Tavares at 7 A.M. I will be
driving the county van which can hold ten addi-
tional people. Please sign up as soon as possi-
ble if you would like a ride. Our first stop will
be at McKinnon Corp's grove in Felda. Maury
Boyd manages this grove which was diagnosed
with greening back in 2005. Instead of remov-
ing infected trees, Maury has implemented a
nutritional program, that has captured the at-
tention of the citrus industry. In 2005 the grove
was PCR confirmed for greening. The grove
was in decline, having greening symptomatic
foliage and fruit. Today the grove has less vis-
ual foliage symptoms and "normal" fruit. What
is happening? No one knows for sure but it has
sparked interest in researching the procedures
and results.
From the McKinnon grove we will go to the Uni-
versity of Florida's Southwest Research and
Education Center in Immokalee to have a BBQ
lunch. My hope is we will be able to tour the
new greening PCR facility that is scheduled to
run grower greening samples in the late
spring. This depends on if the equipment has
arrived by 2/1. We also will be visiting Coop-
erative Producers, Inc's grove to hear and see
what production practices are being imple-
mented to combat greening in their groves.
The cost is $15.00, please call Maggie at 352-
343-4101 to sign up by Jan. 25th.

Nighttime OJ Meeting
Feb. 19th 6PM-9PM

Central Florida citrus growers responded that
weed control was the second most important
topic in the 2007 survey. To address this
there will be a night time OJ meeting on weed
control in citrus at the Lake county agricul-
tural center in Tavares. Our speaker will be
Dr. Meg Singh. Dr. Singh has over 20 years of
experience working with weed control in cit-
rus.
As part of the program a BBQ dinner spon-
sored by Helena and Triangle chemical com-
panies will be provided starting at 6 pm. So if
you would like a free meal and to learn more
about effective weed control in your groves
please RSVP to Maggie at 352-343-4101 by
Feb. 15th. An accurate head count is needed
to ensure enough food. CEU's applied for.

Mature Citrus Mentors (Old Timers)
March 18th 11:00-?

Did you work the grove with a hoe growing
up? Do you remember the '62 freeze? Then
you maybe considered an Old Timer. This
year we will again be reuniting with old
friends and transferring knowledge from our
citrus industry elders.
If you are an old timer please plan on joining
us at the Lake County Agricultural Center in
Tavares starting at 11 AM. There will be a
BBQ lunch provided, cost is $20. Registration
is required. Please register with Maggie
Jarrell at 343-4101 by March 7th.

Greening Summit

Spring 2008

The greening taskforce and the multi county
extension agents are putting on a Greening
Summit in three locations across the state.

The locations and dates have yet to be deter-
mined, but we will advertise as soon as they
are set (should be early Jan. 08).

The idea of the Summit is for growers to come
together and share their ideas and experi-
ences with one another concerning greening
production practices. This is your opportunity
to express your opinions concerning greening!











USDA Designates 58 Florida

Counties As Primary Natural

Disaster areas Decision

allows growers to apply for

USDA assistance.

The U.S. Department of Agriculture desig-
nated 58 Florida counties as primary natural
disaster areas because of losses caused by
drought that occurred on Jan. 1, 2007 and
continues. Brevard, Lake, Marion, Orange,
Seminole, Osceola, and Volusia counties are
all designated counties. Qualified farms
are eligible for low interest emergency
(EM) loans from USDA's Farm Service
Agency (FSA), provided eligibility require-
ments are met. Farmers in eligible counties
have eight months from the date of the dec-
laration to apply for loans to help cover part
of their actual losses. FSA will consider each
loan application on its own merits, taking
into account the extent of losses, security
available and repayment ability. FSA has a
variety of programs, in addition to the EM
loan program, to help eligible farmers re-
cover from adversity. USDA has also made
other programs available to assist farmers
and ranchers, including the Emergency
Conservation Program, Federal Crop Insur-
ance and the Noninsured Crop Disaster As-
sistance Program. Interested farmers may
contact their local USDA Service Centers for
further information on eligibility require-
ments and application procedures for these
and other programs. Additional information
is also available online at: http://
disaster.fsa.usda.qov.

La Nina -Winter Drought
From the Southeast Climate Consortium
www.agclimate.org


La Nifia is commonly thought of as the opposite
of El Nifio. Under La Nifia conditions, sea surface
temperatures along the equator in the eastern
and central Pacific Ocean are a few degrees
colder than normal for a minimum of five
months. La Nifia typically returns every 2 to 7
years. Colder than normal sea surface tempera-
tures have intensified and spread throughout the
eastern and central Pacific Ocean near the equa-
tor. The colder than normal water has now taken
the classic La Nifia pattern and has reached at
least moderate strength by most measures.
Stronger than normal easterly trade winds over
the area, the mechanism responsible for driving
the development of La Nifia, were strong and
widespread in the month of September. This is a
good indication that the La Nifia will persist and
possibly strengthen further throughout the fall
and into winter. In their latest discussion, NOAA
is predicting a weak-to-moderate La Nifia. In
light of recent developments, we think there is
greater chance that this La Nifia reaches moder-
ate or even strong levels. The warmer tempera-
tures will impact winter crops and fruit produc-
tion, resulting in less chill accumulation over the
course of the winter season. Warmer tempera-
tures will also mean greater evaporation rates.
Due to the jet stream configuration described
above, severe or damaging freezes are less
likely during La Nifia than in neutral years. How-
ever, the risk of early or late season freezes (like
in April of 2007) does not seem to be affected by
the Pacific Ocean. For more information about
La Nina go to www.agclimate.org.

The Florida Automated Weather Network
(FAWN) has overhauled its Web site to
make looking for weather data to protect
their crops. The improved site which de-
buted in mid-October has a new user inter-
face and database. The site features a more
modern look, streamlined navigation, gives
access to additional resources and its data-
base is more efficient. Also a new web and


data server is in place for maximizing the site es-
pecially during times of heavy use like freeze
events. The servers are monitored 24 hours a
day, seven days a week by University of Florida
personnel at the Institute of Food and Agricul-
tural Sciences. If you have yet to look at the new
site give it a try at :

http://fawn.ifas.ufl.edu/


You will find on the site:

1. Cold protection toolkit for assisting cold pro-
tection decision making.

2. A citrus irrigation scheduler.

3. Alter-rater for assistance determining when to
spray for Alternaria based on weather condi-
tions in your area.
