Pam Russ with her husband, Ralph.

Pam Russ, CREC's librarian and website
manager, is retiring on March 31.
Pam started her CREC librarian career in 1966,
managing what is now the largest agricultural
collection in central Florida with over 15,000
volumes. Pam has also maintained a sizable
collection of historical documents and
photographs. Over the years, she has adeptly
guided the library through changes in
computerization. In the 1990s, she created a
website for CREC and since then has overseen
its development and growth as webmaster.
Pam was suprisedby a small group of friends
and colleagues at a luncheon on Jan. 21, followed

From the Director
Some good news! We have received
acceptance letters from two faculty candidates
who were interviewed late in 2004 for positions
here at the Center. Dr. Reza Ehsani, Assistant
Professor of Agricultural and Biological
Engineering, has accepted the position of
Assistant Professor of Agriculture and
Biological Engineering at CREC, and will focus
on programs associated with precision
agriculture and citrus harvesting systems. Dr.
Ehsani and his wife will be moving to Florida in
April. Our second faculty position, Assistant
Professor of Food Processing Engineering, was
accepted by Dr. Jose Reyes, currently
completing post-doctoral studies at
Washington State University. Dr. Reyes will be
joining the CREC faculty in March of this year.
We are very happy with the outcome of these
two searches, and special thanks are given to
Dr. Bill Miller and the search and screen
committee for the precision ag/harvesting
position, and to Dr. Renee Goodrich and the
search and screen committee for the Food
Processing Engineering position. Other
activities around the Center include the review
and updating of our Center organizational chart,
and first steps towards making some changes
as indicated in our strategic planning efforts
over the past year or so. With other impending
staff and faculty changes, we are working to
invest personnel resources in the best way to
support the programs of the Center.

Thanks to UF President Machen, USPS and

Toll-Free Florida Citrus
Disease Hotline
As we enter the flowering season,
Florida citrus growers should be on the
alert for outbreaks of postbloom fruit drop
(PFD), scab, and Altemaria brown spot.
Growers can call a toll-free hotline
sponsored by Syngenta Crop Protection
(1-866-365-3017) for the latest disease
reports. Dr. L.W "Pete" Timmer, Extension
plant pathologist at CREC, provides
current information on recent outbreaks,
the status of the bloom and other relevant
news on the hotline.
Information on PFD and other foliar
fungal diseases is available on Timmer's

Albrigo, who organized the luncheon,
kept details of the luncheon so secret
that even some of the attendees were
unaware of the nature of the event. Pam
had previously expressed a desire for no
retirement fete, but Dr. Albrigo and others
felt it fitting to honor Pam's service to
CREC, the citrus industry and library
community for nearly 40 years.
The library includes books,
magazines, journals, reports, brochures,
newsletters and other documents related
to the citrus and ag industries. The
collection includes collections of the

Proceedings of the
Florida State
Horticultural Society rr
(1917-present) and
collections of agriculture magazines.
Pam has also developed a searchable
database of over 23,930 popular and
technical articles on citrus. In addition
to assisting library visitors, Pam also
responds to numerous requests for
informationby phone or e-mail.
Pam has also been active in the
center's public relations activities
throughout its history.

From the Director...
from p. 1
TEAMS merit increases were established and
awarded in January. Despite the lack of a raise
approved by the Legislature for 2004-05, President
Machen designed a plan for this year that called for
an average of 1.5% merit increase for eligible
employees in USPS and TEAMS. During January,
supervisors were asked for information necessary
to rank all eligible employees at CREC, resulting in a
merit raise across our unit that ranged from 0.5% to
4% in a few cases. Thanks to all who assisted in this
effort to reward the employees of CREC, and
congratulations to the staff on their excellent support
of the Center and its programs.

The new faculty accountability system came online
in February. This new system promises to provide a
very useful system for capturing Research, Teaching
and Extension program activities and

Student Outreach and Accomplishments

This month's issue includes news on
science fair accomplishments! For those
unfamiliar with school science fairs, it
involves student research in science and
engineering topics (elementary to high
school). The students must complete a
research project, which can range from a
simple experiment to an extensive, in-depth
study. The students present their research,
typically in a poster-type display or exhibit
(some competitions involve oral
presentations), and are judged on criteria
such as scientific method, etc. There are
competitions at the school, county or
regional, state, national and international
Several CREC scientists and engineers
mentor students and serve as science fair
judges, an schools are always looking for
help in these areas. Dr. Russell Rouseff
served as judge in the chemistry cateogry
at Jewett Academy in December, and Dr.
Samunder Singh served as judges at Jewett
Academy and Denison Middle School in
December. Dr. Jim Syvertsen served as a
judge in the botany category in the Polk
County Regional Science and Engineering
Fair, and points to a need for experienced
researchers to lend their expertise to this
Dr. Syvertsen writes of his experience:
"I recently served as a Science Fair judge
in Botany at thejunior high school level. It
was a rewarding experience that
underscored the difficulties science
teachers must have getting students
excited about science. For example, half of
the experimental projects only treated one
plant to compare to one control plant.
Thus, we had discussions about
developing a hypothesis, experimental
design, replicates and variation. Even more
of a problem, one of the judges I worked
with did not appreciate why one needed
replications for valid testing. More
scientists from CREC need to volunteer to

be qualified judges in
these programs to get
kids excited about asking
scientific questions."
(The coordinator of this
science fair assured us
that this person would
not be asked to judge in

implementing a research project. However,
only a small portion of the population is
qualified to provide such guidance. CREC is
working on some web-based resources to
assist students with science fair and other
related activities, with a particular interest in
reaching students that do not have access
to research laboratory equipment and
The State Science and Engineering Fair
of Florida will be April 6-8 at the Orange
County Convention Center in Orlando. This
article includes only a partial list of the
children and students affiliated with CREC.
Good luck to all our aspiring young scientists
and engineers! Remember, for all students
that participate in science and other activities,
the true prize is in the
excitement of learning and
discovery! Also, if you are

Bao Tram, a worked with Dr. Jim
Graham and Marty Dekkers at CREC, won
first place in the Senior microbiology
categoryand Best of Show in the senior
division at the Polk County Regional
Science and Engineering Fair. Her research
involved evaluating the effectiveness of
chemical treatments for citrus bacterial spot,
which is caused by a bacterium similar to
the species that causes citrus canker (citrus
bacterial spot is used as a "surrogate" for
citrus canker in research at CREC because
specialized quarantine facilities are required
in areas that do not have citrus canker).
Bao writes, "From a previous experiment
of using different concentrations ofRocksil
I calculated the amount of Aluminum it
contained to get my concentrations for this
experiment. I also used Kocide, the
fungicide used in the fields, as one of the
solutions to be tested. We used a more
natural approach to inoculating with 108
bacteria count. The results were interesting
in that the lowest concentration of
Aluminum had the most effect in reducing
[citrus bacterial spot]. I could have not done
my experiment without the tremendous help
of Dr. Graham and Mr. Marty Dekkers."
Bao's favorite school subjects are
science and math. After graduating from
high school this year, she will enter college
to major in chemistry or microbiology and
pursue a career in the medical field.

Rhonda Schumann in Dr. Nigg's lab has
mentored science fair students the past three
years, this year mentoring a student with a
Carribbean fruit fly project. One of her past
students was Meredith Morton, a UF
journalism major who has worked at CREC
for the past two summers. Meredith, who
competed internationally with her science fair
projects, is interested in scientific writing and
will return to CREC this summer as a public
relations intern.

Dr. Monica
Lewandowski did
five presentations to
7th grade girls about
careers in science at McKeel Academy of
Technology's "Girls Invent the Future"
workshop on Jan. 14. The event, which is
organized by the Girl Scouts, gives girls
exposure to various careers as well as
practical advices in areas such as self-
confidence and anger management.
Dr. Lewandowski also provided a CREC
tour to a Girl Scout troop from Lakeland on
Feb. 7.

CREC also participated in the Florida
Citrus Festival. A CREC exhibit in the Orange
Dome was part of the citrus exhibits, and
poster illustrating some of last year's
hurricane damage to citrus, created by

Gretchen Baut and George Brinkley, was
selected for display in the entrance of the
Orange Dome.
CREC's biggest participation in the
festival involved the school program. Area
elementary schools took field trips to the
Citrus Festival on Feb. 1-2. The students,
ages 4-7, participated in special programs
and activities that took place before the
festival was open to the public. Linda
Murphy (pictured below, somewhere in the
sea of students) helped thousands of


students plant citrus seeds, and Karla
Flynn bravely helped with a fingerpainting
activity. Over 1300 students attended the
program each day, so you can imagine how
difficult these assignments were.
Monica presented an educational skit,
sometimes addressing over 400 students
at a time! Monica portrayed a space alien,
traveling in a spaceship and landing in a
citrus grove at CREC. Through the window
of the spaceship, as seen as a Powerpoint
presentation, Monica and the
students explored different uses
for citrus fruit as well as some
insects, leaves and soil
encountered in the grove.
Gretchen Baut created alien
stage props, and student intern
Joseph Barnes created
k animations of a Diaprepes root
weevil and space probes
collecting leaves. Special thanks
to Gretchen for her audio-visual and video
expertise and creating stage artwork and
song verses for the presentation.

Festival, provided special effects with
