Topsin M Section 18 Label
It appears unlikely that the Topsin M WSB
Section 18 (Emergency Use) label for PFD
control on Florida Citrus will be renewed.
The Topsin M section 18 expires on March
19, 2009. In practical terms, growers who
have blocks with a history of PFD and have
product on hand should apply the material
prior to March 19 (if timing is appropriate).
Although there are alternatives, Topsin M is
probably the most effective fungicide against
PFD.

Agri-Mek 0.15 Aerial Label
A supplemental label for Agri-Mek has been
issued to allow aerial application for Citrus
Leafminer control only. Label conditions
require a minimum of 10 gallons of water per
acre be used when applied by air.


New Citrus Pest
The Lime Swallowtail butterfly has recently
been found in Southeast Florida. In recent
years the insect has been found in
Hispaniola and Jamaica and has found its
way to Florida like so many other pests.
The butterfly is first cousin to our indigenous
Swallowtail butterfly, which is the adult stage
of the "orange dog" larvae that is so fond of
feeding on young citrus trees. The larval
stage of the Lime Swallowtail Citrus is
similar but distinguishable from the familiar
orange dog larvae. Citrus is only one of a
number of favored hosts for this new insect.

Citrus Greening Symposium
In order to attempt to stay as current as possible with respect to Citrus Greening disease
management, a Citrus Greening Symposium at the 2009 Florida Citrus Growers' Institute has
been scheduled for Tuesday, April 7, 2009 at the Stuart Conference Center in Bartow. The
Symposium will feature topic areas including production systems, plant improvement, vector
management horticultural responses to HLB, disease detection and spread.

Presenters will include resource individuals from UF/IFAS, USDA/Agricultural Research
Service and the citrus industry. The program is sponsored by UF/IFAS Extension, the Florida
Citrus Production Research Advisory Council and the Greening Research Task Force.
There is a lot of research work going on at this time on Citrus Greening disease and new
information that could help you make your best management decisions is being released on a
frequent basis.

Attendance at the Citrus Greening Symposium will be limited to 300 persons. Pre-
registration is required, because a generous industry supplier is going to provide lunch to
participants. To get that accomplished, click on the hyperlink below to see a copy of the
program, directions to the Stuart Convention Center and registration information.

Return of La Nifia
I think we have all seen signs that it is going to be a long, dry spring; if we can get past the
winter that we are still enduring. Sea surface temperatures along the equator in the eastern
and central Pacific Ocean have cooled substantially in the last few months, marking a return
to La Niia. This La Niia is expected to last at least through the remainder of the winter and
spring seasons, with this climate phenomena expected to bring a warmer than normal and
dry climate pattern to the Southeast U.S. during this time.

For more information on climate impacts in the Southeast, see the latest climate outlook:

Predicting the 2009 Bloom Period
In my last newsletter, I mentioned Dr. Gene Albrigo's Flower Bud Induction Overview and
advisory model. At that time, I wrote that the Model perhaps indicated that we were looking
at an early bloom. Well, within a week we experienced some of the coldest temperatures in a
number of years and we've had one cold spell after another ever since.

This model basically utilizes the number of hours accumulated below 68 degrees to predict
when our trees are going to bloom. I spoke to Dr. Albrigo this morning and he indicated that
he will be updating the Model this week.

As I write this newsletter, another blast of cold air is advancing down the state. The result is
probably going to be a bloom period that would have to be regarded as falling within the
historic norm. In any event, to help you make your management decisions that depend on
the timing of the bloom, visit Dr. Albrigo's Flower Bud Induction website:

Updated State Citrus Greening Map
Click on the following web address to download a current map of Citrus Canker and Greening
finds in the state. It is no surprise that the Greening lab at SWFREC has a backlog of
samples to be tested for suspected citrus greening as growers increase greening surveys.

Just for Fun
Bubba and Elwood had landed tickets on the 50-yard line for the Florida Georgia game in
Jacksonville. Midway through the first quarter, there was still an empty seat next to them.
Bubba finally remarked to the man on the other side of the empty seat, "I can't believe you
couldn't find somebody to use the ticket for this seat!" The man with the Georgia bulldog hat
replied, "It's my wife's seat, but she died." Bubba felt awful, and said, "I'm sorry to hear that,
but you couldn't get one of your friends to come with you?"
"Nope", the man replied, "I tried, but they all decided to go to the funeral."

The ventriloquist was touring the Southeast and has a stop at a bar in southern Alabama.
He's going through the usual stupid redneck jokes, when a big, burly guy in the audience
stands up and declares, "I've heard just about enough of your mouth we ain't all morons
here in Alabama!" Somewhat afraid for his well-being, the ventriloquist starts to apologize,
when the big ol' boy interrupts him and says, "You stay out of this mister----I'm talking to that
smart mouth little fella on your knee!"

And finally, a few Redneck Etiquette Tips for All Occasions:
1. Never take a beer to a job interview
2. Always identify people in your yard before shooting at them
3. Always say "Excuse me" after getting sick in someone else's car
4. It's considered tacky to take a cooler to church
5. Even if you're certain that your are included in the will, it's considered tacky to drive a
U-Haul to the funeral home
6. Always provide an alibi to the police for family members
