UF Bridges:
Do You Have A GatorLink
You Will Need One!
by Monica Lewandowski
UF is transitioning business and related soft-
ware systems to an entirely new system that
will allow UF employees greater access, and
responsibility, over everything from personnel
records and purchases to event calenders. It
will be a monumental change, slated to occur
on July 1, that will help move UF systems into
the 21st century. One aspect of this system
that seems to have generated a lot of buzz is
timekeeping procedures. Contrary to rumor, it
is not expected that all UF employees will need

Citrus Disease Hotline

Dr. Pete Timmer posts timely news
on citrus diseases, the status of the
bloom and other relevant news on a toll-
free hotline sponsored by Syngenta Crop
Protection (1-866-365-3017).
Information on postbloom fruit
drop, Alternaria brown spot, scab and
other diseases is available on
Timmer's citrus pathology website
including online tools to aid growers in
determining need and timing of sprays

(upper right) and Liz
Felter (lower right)
presented a marketing
workshop at CREC on
Jan. 30 to UF/IFAS

faculty and those associated with public-relations
departments. The workshop was intended to provide
an introduction to marketing what it is, how and why
to do it. Nationwide, universities have adopted
marketing strategies and commercial techniques that
are a standard part of the business world all to
increase public awareness, enhance their image and
generate more support. "We have found that IFAS
programs are well known, but they're not well-known
as IFAS programs," said Don Poucher, Assistant Vice-
President of Marketing and Communications. Liz
Felter suggested that marketing strategies can be a
simple as wearing a nametag or placing the UF/IFAS
logo on the first and last slide of Powerpoint
presentations to identify who you work for. Don
Poucher is the Assistant Vice President of Marketing
and Communications for UF/IFAS, Liz Felter is the
Associate Director, and Kimberly Mansfield is
Marketing Coordinator. They are planning similar
workshops at other RECs around the state.

State Workers Fired For

Canker Violations
Two state Florida Dept. of Agriculture
workers were fired for violating citrus can-
ker decontamination rules. According to
newspaper reports, the two workers did not
spray themselves after inspecting yards
and supervising cutting crews.
CREC employees are reminded that if
you work with citrus materials or tissue, or
enter greenhouses or groves, you must
follow regulations on decontamination/
disinfestation of vehicles, tools, equipment
and personnel working to prevent the
spread of citrus canker and other pests and
diseases. There are also strict limitations
on the movement of fruit off Center. Dr.
Timmer has a sprayer and disinfectant if
you need to borrow one. If you have any
questions, please contact Dr. Pete Timmer
orDr. Chung.

Tools of the Future ...

Computers and satellites?

Over 140 people attended the Precision
Agriculture for Florida Citrus II at CREC on Jan.
21. Precision ag utilizes computers, geographic
information system and global positioning
system technology to collect and utilize data on
everything from yield and soil characteristics to
tree size and labor records. At CREC, engineers
and scientists from various disciplines are
working to adopt precision ag, currently used in
row crops, for citrus. The collaboration includes
citrus growers and precision ag businesses as
well as researchers with expertise in horticulture,
engineering, soil science and citrus nutrition. At
CREC, the following people are involved in
precision ag research: Dr. Bill Miller, Dr. Masoud

Salyani, Dr. Arnold Schumann. Prof. Emeritus Dr.
Jodie Whitney, Prof Emeritus Dr. Adair Wheaton,
Dr. Qamar Zaman, Dr. Hong Li, Dr. Jim Syvertsen,
Jill Dunlop, Dr. Brian Wei, Sherrie Buchanon,
Sharath Cugati, John Roegner and Kevin Hostler.

Florida Citrus Festival
The Florida Citrus Festival, Jan. 15-25
in Winter Haven, is a major event and fund-
raiser for the Florida Citrus Showcase, an
organization involved in promotional ac-
tivities for Florida citrus. Jane Waters, the
Showcase's public relations director, and
Bobby Fuqua, the Showcase Executive Di-
rector, have implemented some new edu-
cational programs, including field trips that
brought elementary students to the Citrus
Festival to learn about citrus.

Dr. Monica Lewandowski and Gretchen
Baut participated in the school program
on Jan 16. Over 150 students visited the
Festival in the morning, before it was open
to the public, from schools in Winter Ha-
ven (Jewett Elementary), Fort Meade and
Lakeland. Monica and Gretchen developed
a program that included songs, a story and
a Powerpoint presentation, "Citrus ... A -
Z!" The students also squeezed orange
juice and were entertained by Irving the
Clown and a magician.

Careers and More Careers
Girls Invent the Future
Dr. Monica Lewandowski spoke to over
60 seventh-grade girls about science careers
at the McKeel Academy for Technology in
Lakeland on January 19. Monica gave five
presentations throughout the day, speaking
to girls about CREC programs and discuss-
ing programs in food science, horticulture,
marketing and plant pathology. She showed
the students everything from pommelos and
kumquats to "glowing" plants (tobacco
plants infected with tobacco mosaic virus,
tagged with a green fluorescent protein) -
hoping to give them some insight into the
variety of careers in science and related
fields. The event was part of the Girls Scouts
of America "Girls Invent the Future" cam-

UF CALS Career Day
Dr. Monica Lewandowski represented
CREC at the UF College of Agriculture and
Life Science Career Day on the Gainesville
campus on Feb. 4. UF students were invited
to speak with representatives about career
and graduate opportunities. Several UF de-
partments were represented as well as ag-
related companies and businesses. Monica
collected a few resumes; if you are interested,
they are available for your examination in
the CREC Personnel Office.

Photo Corner

What is "Color Fading?"
Some colors appear faded when projected
onto a wall (or on film). Your Powerpoint
presentation may look superb on your
computer monitor, but these same colors
may look "faded," or pale, when pro-
jected by a computer projector onto the
wall. Consequently, some text and dia-
grams may be hard to see during your
actual presentation. To be sure check it
out ahead of time Sandy Hatch in audio-
visual (Ext. 1220 or ash(@crec.ifas.ufl.edu)
will gladly set up a computer projector
for you to preview your presentation in

Don't Distort
To resize photos in Powerpoint (and many
other programs), click on the photo to select
it and "grab and hold" one of the black boxes
on a corer. Press and hold down the shift
key and drag the photo in and out (while still
pressing the shift key) to U
the desired size. Pressing
the shift key will keep the
photo at the same dimen-
sions that is, it won't get -
too thin or wide and be-
come distorted.
