I hope everyone had an enjoyable holiday season. Alison and I enjoyed watching our two children Lillian
(almost 3 years old) and Elijah (almost two years old) open their presents, what a blessing the holidays can be.
The first month of winter has been down right spring like. I have observed some trees blooming already this
year. We are in the mist of an El Nino which is supposed to bring Florida cooler temperatures with above
average rainfall. So much for climatologist... just when they think they have mother nature figured. Speaking
of weather California has suffered a major freeze with estimated losses of 700 million dollars. Damage to trees
will effect next years citrus crop as well, one would think we will be seeing higher fruit prices next year.

I have been hearing a lot of people saying they believe citrus greening is most likely spread all over Florida.
Greening positive psyllid have been found as far north as Jacksonville, and trees showing the disease seem to be
occurring in new areas of the state. Scouting your groves for symptoms of citrus greening is extremely

important. If you find a tree or trees with greening symptoms sending leaf samples to be tested is advised. If it
is found that you have greening positive trees, removal is vital to keep the inoculum levels low. The more
infected trees that are present in your grove the more likely non-infected trees could be exposed. I would wait a
before doing any resetting of trees until you were certain the grove did not have any more infected trees. I
would not recommend resetting trees in a greening positive grove because they would never bear marketable
fruit and the tree would die if it became infected with the bacteria.

You may have read recently in the news about the USDA interest in guava trees to combat citrus greening. This
idea came from Vietnam. Farmers in Vietnam have inter-planted guava and citrus trees on a one to one ratio,
and have trees that have lived to be fifteen years old in areas with the greening disease. However, is no
greening present due to the guava trees or just random chance due to the location? The USDA is planning on
testing the idea of inter-planting guava and citrus in south Florida. The theory is that the naturally occurring
volatile compounds maybe repelling the pysillid. One of the projects looks to utilize these compounds as a
spray for citrus. So should you rush out and plant guava trees? No, there is a lot of unknowns about the
potential positive aspects of guava trees however, there are some known negatives about Guava's which
include high levels of fruit fly infestation and a tendency to become a pest species.

A new citrus pest is on the horizon called the Lime Swallowtail. The Florida Department of Agriculture and
Consumer Services Division of Plant Industry has issued an advisory on its site about the lime swallowtail,
Papilio demoleus L. This swallowtail, found in the Caribbean in 2004 in the Dominican Republic, has spread to
Puerto Rico. Since it is a strong flier, it is expected to reach Florida. After arrival and establishment in Florida,
spread of the lime butterfly through the entire southern United States to the West Coast is very likely within a
few years. Lime swallowtail larvae feed on all species of citrus, as well as related plants in the plant family
Rutacea.



Winter Production Practices for Peaches, Nectarines, and Plums will be held in Winter Garden on February
1st at Water Conserv II from 9:30-11:30 am. Dr. James Ferguson a horticultural specialist will be showing
participants proper pruning techniques on peach trees. This demonstration allows active participation for some
"hands on" experience. There is growing interest in stone fruits and an attempt is being made to develop a
profitable and sustainable stone fruit industry in Florida. If you are interested in learning more about stone
fruits I encourage you to attend. For directions please see the attached flyer. For more information or to RSVP
please contact Maggie Jarrell at 352-343-4101 or mjarrell@ufl.edu.

We will be having an OJ Meeting in Tavares at the Lake County Agricultural Center on February 13th from
9:00 am to 11:00 am. Dr. Kelly Morgan from UF/IFAS will discuss Irrigation Scheduling: Improving Nutrient
Use Efficiency. Also included will be an overview of irrigation tools on the Florida Automated Weather
Network. Bobby Brown from the Lake County Mobile Irrigation Laboratory (MIL) will be demonstrating their
procedures for assisting landowners with irrigation system efficiencies. The MIL will show the type of
information they collect from irrigation systems, how they analyze the data, and the types of recommendations
given for system improvements. Efficient water application is essential for crop production, water
conservation, water quality, and financial savings.

There will be a Citrus Greening Identification and Sampling workshop in Cocoa on March 6th, 2007 from
10 AM to 11:30 AM. The class should aid growers, managers, and supervisors in the field identification of
greening and procedures for getting samples tested. Speakers for the class include Holly Chamberlain and Ryan
Atwood both from UF/IFAS. CEUs will be offered for individuals with valid restricted use pesticide license in

We will be having an OJ Meeting in Tavares at the Lake County Agricultural Center on March 13th from

We will be touring BriteLeaf Citrus Nursery in Lake Panasoffkee on March 27. BriteLeaf like all of the
Florida citrus nurseries have been investing heavily in their infrastructure so they can be compliant with the new
regulations of the Citrus Health and Response Plan (CHRP). Nate Jameson owner of BriteLeaf and former
president of the Florida Citrus Nurserymen Association will be sharing his thoughts on the new challenges
faced by citrus nurserymen. Also, bureau chief Michael Kesinger from the Division of Plant Industries Bureau
of Citrus Budwood Registration will update us on the citrus budwood supply and the measures being undergone
to protect that supply. We will be leaving the Lake County Agricultural Center at 8:00 am and returning at
noon. We will provide some transportation, but space is limited. Please contact Maggie Jarrell at 352-343-

NRCS Offers Water Management Incentive Payments in an effort to improve irrigation water management.
The payments are a flat rate of $50.00 an acre for those producers who follow a USDA water management plan.
The previous rate was $5.00 an acre. This program can be up to three years. The irrigation water incentive
program is being offered thru the environmental quality improvement program (EQIP). The deadline for
signing up for this or any other Farm Bill program is December 15, 2007. For more information about this
program you can contact your local NRCS district Conservationists.

Operation Cleansweep is a program that provides farmers, nursery operators, golf course operators, and pest
control services a one-time safe and economical way to dispose of their cancelled, suspended, and unusable
pesticides. Some of these materials are very old and may be in containers that are deteriorating. If you have
need or know you will have a future need to dispose of old chemicals the Department of Agricultural &
Consumer Services will pick them up at your location. For more information contact Robin Waddell at
waddler@doacs.state.fl.us or 877-851-5285.

US Sugar has established the Southern Gardens Diagnostic Laboratory for Greening Sampling. US
Sugar is working with citrus growers throughout the state to diagnose suspect trees that may have citrus
greening disease. Included in this newsletter is the sampling protocol for the submission of samples to the
southern gardens diagnostic laboratory. Read the directions carefully as time of year, type of tissue, and
properly filled out paper work are important. Typically results take about 7-10 days from the time the samples
are received, the amount of time is dependent on the amount of samples the lab has to process.

A new Florida citrus rootstock wheel has been created and is available at the UF/IFAS bookstore. The wheel
contains newer rootstock varieties such as US-852, US-897, US-802, Kinkoji, and Goutou. The wheel can be
ordered at 1-800-226-1764 or online at http://www.ifasbooks.ufl.edu for $10.00.
