Florida Citrus Production Research Order Referendum
Between now and November 16th, citrus grove owners should be receiving a
voting ballot regarding a new Florida Citrus Production Research Order (box tax
to support research). This marketing order has been in existence since 1991 and
has been renewed every six years since that time. The order will generate
continued funding for citrus research which is more critical than ever.
Several opportunities are available for you to gain more insight into the
referendum and the issues. A statewide conference call will be hosted by Florida
Citrus Mutual on November 12th at 10:00 a.m. To join the conference call,

dial 1-866-544-4631 and follow the instructions. You might also contact one of
the various grower organizations around the state for information. You can also
click on the hyperlink at the end of this section for a "white paper" developed by
Florida Citrus Mutual and FDACS on the Proposed Citrus Research Order which
outlines the basics of the order and contains answers to Frequently Asked

Be sure and mark your ballot and mail it by December 4th. If you do not get a
ballot in the mail by November 20th, they will be available at the St. Lucie
Cooperative Extension Office.

2010 Florida Citrus Show

Here's another reminder about the Florida Citrus Show (formerly known as the
Indian River Citrus Seminar) for 2010. The venue for 2010 will again be the
Havert Fenn Center in Ft. Pierce with the 2-day show being held on January 27-
28, 2010. Put those dates on your calendar so you don't schedule any conflicts.
We have also scheduled the Indian River Ag Worker Training Day for
Wednesday, January 20, 2010. Much more information on both these events will
be forthcoming in the next several weeks.

NASS 2009 Commercial Citrus Inventory

The newest Commercial Citrus Tree Inventory shows total Florida citrus acres at
568,814 acres, down from a high of 941, 471 in 1970. Orange acreage declined
to 492,529 which is the lowest number since the freezes in the early '80's.
Grapefruit acreage has fallen to a new low of 53,863 which represents only 60%
of the pre-hurricane acreage and just over 40% of the 1970 acreage. Because of
very limited replanting, only 3.6% of the total grapefruit trees are listed in the non-
bearing category. Specialty fruit acreage has declined to 22,422 which is only
about 20% of the 1970 acreage.

The latest abandoned acreage survey released in September showed 27,289
abandoned acres in St. Lucie County, 15,411 in Martin County and 13,220 in
Indian River County.


New Fresh Fruit Shipment Rule

The previous requirement that fruit be inspected and found free of citrus canker
by APHIS has been eliminated for fruit destined to the interstate market in the US
and a number of US territories. However, that previous requirement remains in
effect for fruit destined to some foreign markets, including the European Union.

The new rule allows fruit to be shipped interstate from the Florida canker
quarantine area under a Federal Certificate provided the fruit:
Is packed in a commercial packing house whose owner or operator has
entered into a compliance agreement with APHIS
Is treated with a USDA-approved disinfectant
Is free of leaves, twigs and other plant parts
Is accompanied by a Federal Certificate

This new rule should be a big help to fresh fruit packers and was made possible
by the efforts of a few very dedicated researchers and industry leaders.

Increasing Efficiency and Reducing Fertilizer Costs

EDIS publication SL-222 focuses on the main factors which should be
considered when making good economic and horticultural decisions about your
citrus nutritional program. A summary of the information provided in this fact
sheet would include:

Increasing the efficiency of applied nutrients is a key to economic citrus
Nitrogen and potassium fertilizers affect fruit production and quality more
than any other applied nutrients.
Management practices that improve fertilizer efficiency include:

1. Using leaf and soil analysis to guide fertilization programs.
2. Choosing realistic fertilizer rates based on established guidelines and
expected production.
3. Selecting fertilizer sources appropriate for grove conditions.
4. Careful placement and timing of fertilizer applications.
5. Managing irrigation to minimize leaching of soluble nutrients.

Foliar feeding is appropriate when soil conditions prevent sufficient uptake
of nutrients to meet tree demands.
Phosphorus fertilizer should be applied judiciously because P can
accumulate in the soil.
Micronutrients should be applied only when deficiency symptoms persist.
Keep soil pH in the range of 5.5 to 6.5. Do not overtime.

Quick Reference Guide to Citrus Insecticides and Miticides

This really handy publication was updated again in September '09 and is
available as a laminated handout or as EDIS publication ENY-854. The updated
version includes "Products labeled for application at reduced volume either by
ground or aerial application" on the back side.

IRREC Course Offering for Spring 2010

Those who have knowledge about best management practices for agriculture
are becoming more valuable to their employers and to meet that demand.
Zhenli He, Ph.D, one of the central figures in the development of best
management practices, is offering a new course, Agriculture and
Environmental Quality. Dr. He is an associate professor of Soil Fertility and
Environmental Chemistry at the UF/IFAS Indian River Research and Education
Center in Fort Pierce.
Dr. He said the course is designed for growers and others interested in
protection of the environment with best management practices for agriculture.
"This course will be of significant value to those students who will be involved in
the management of agricultural production and processing industries as well as
to those with a special interest in agricultural pollution control and plan further
study in this area," said He.
The course will be delivered by internet format and will include weekly live chat
room discussion and guest lecture videos. Dr. He will hold office hours to meet
with students at the UF Fort Pierce location. Opening topics will include
concepts relating to agriculture, the environment and its quality, and the
relationships among the three as they relate to sustainable agriculture. Focus
topics will feature wetlands and soil components, their properties and functions
such as filtration, waste disposal and contamination screening. Students will
learn how to identify sources of pollution, how to manage nutrients so that they
will not transform into contamination, how to process waste, land management
techniques, integrated pest management and the particulars of the Food Quality
Act and wetland protection legislature.
An award-winning, widely-published and internationally-recognized scientist,
Zhenli He has served as a scientist and as a professor at institutions in England,
Scotland and in China. Zhenli He has served UF/IFAS as a member of the
graduate faculty for six years, jointly holding IRREC and Soil and Water
Department research and teaching posts with increasing roles of responsibility.

At some point in the process of advertising the recent Low Volume Application
Technology for Citrus Pests program, I wrote that 3.5 CEU's would be offered
for the program. Well, because the program was only two hours long, the
program was only certified for 2 CEU's by the folks at FDACS. The mistake was
all mine because I know very well that 1.0 CEU is granted for every 50 minutes of
program time. My apologies to those of you who showed up for the program,
expecting 3.5 CEU's. On a positive note, the program evaluations indicated that
the program was a good educational experience for most of you.

Just for Fun

Nugene buys a $1 ticket and wins the lottery. He goes to lottery headquarters to
claim it and the lottery official indeed verifies his ticket number.

Nugene says, "That's great, now I want my $20 million."

The man replied, "No, sir. It doesn't work that way. We give you a million today
and then you'll get the rest spread out for the next 19 years."

Nugene replies, "Oh, no. I want all my money right now, I've got bills to pay and a
fancy truck to buy!"

Patiently, the lottery official once more explains that he would only get a million
that day and the rest during the next 19 years.

Well, now Nugene is furious and says, "Look, I want my money! If you're not
going to give me my $20 million right now, then I want my dollar back!"
