75th ANNUAL FLORIDA CITRUS FESTIVAL
The ril Florida Citrus Festival was held at the Baseball Dome
in Winter Haven January 14-24, :'Wl,. CREC's exhibit booth at
the rfe.ii\l was staffed by CREC employees, many of whom
spent weekends and evening hours at the booth. Exhibit
volunteers distributed graperrun and ordn-,cs and passed out
CREC handouts, Extension publications and research articles.
Alta Church. one of the exhibit volunteers, noted that many of
the fair attendees were from our-or'-ilate and were unfamiliar
with CREC "I told them about the knowledgeable and
wonderful people we have at CREC," she said. Cand,
Reynolds, another volunteer, agreed. 'MNan of the visitors
didn't realize that the University of Florida had a place in Lake
.A IIred dedicated to citrus research, and that we are available to
help the public and grower, They were ,lad to find out about
CRFEC and what we do," noted Reynolds.
"Thank you to the volunteers who staffed the booth and who
helped with the preparation and set-up," said Monica
Lewandowski. "Many or the volunteers spent hours of their
own time to help out with the booth."

at CREC's exhibit booth. Several festival attendees
stopped by the booth for information on citrus.
Several air-eoers were interested in in format ion about dooryard
citrus. COnec t the booth's visitors was a landscape architect with
the Department ofTransportation. who is working to incorporate
citrus into some roadside landscapes. "Because citrus is such an
important part of this area, we though it would be an excellent
idea to incorporate citrus into some of our landscapes. We are
planting cal.imondin trees in some parts ofLakeland," according
to the architect.

ISC IXth Congress 2000:
"Entering the Fifth Millennium of Recorded
According to Dr. Gene Albrigo, President of the ISC and ISC
2000 Congress General Chair, the theme of the ISC 2000
Congress is "Enering the Fifth Millennium of Recorded
Citrculture." With the first known records ofcitriculture dating
back 4000 years, the ISC 2000 Congress was deemed a finding
event to commemorate this milestone.
The International Society rf Citriculture is preparing to release
the first announcement for the lXth Congress at the Coronado
Springs Resort, Disney W world, Florida, December 3-7, 2000.
The first announcement, detailed in a color brochure, contains
S information on the local arrangements, which are being
coordinated b% Drs. Walt Kender and Clay McCoy, Local
Arrangements Committee Co-Chairs, the Congress program and
tours. Brochures '. ill be mailed out to current ISC members. If
you do not receive a brochure, additional copies will be available
at the Switchboard by mid-February.
Preliminary information on the ISC Program, including a list of
current sessions that in the planning stages, is also provided in
the first announcement. Drs. Jim S vsensen and Fred Davies are
Program Committee Co-Chairs.
Two logos for the IXth Congress were selected. There were
several excellent entries, and the selection committee would like
to thank all entrants it was a tough decision!
In the logo dezigined by Diana Drouillard, the international
cooperative aspect of the Congress is depicted by light- and
dark-skinned hanr J supporting a symbolic earth/citrus fruit. The
banner encircling the earth features the new millennium.
Drouillard also won a logo design contest for the Center for
Natural Resource UF IFAS, Gainesville. Her artistic talents are
no secret to CREC she has been the creative force behind
several CREC events, including recently the 19o8 Christmas
I II I
By Dr. Dennis Lewandowski
The second logo that will be a part of the ISC 2000 Congress
was contributed by Dr. Dennis Lewandowski. The logo features
a map of Florida The zeros in "2000" are represented by two
oranges and the ISC logo, a standingg globe/citrus slice.
Lewandowski wanted to combine three images easily l recon Ized
by citrus researchers: the state of Florida, oranges and the ISC
logo. The oranges also signify that Orange County is the site of
the IXth Congress.
Pam Russ has been working with the artists to put the designs
into a graphics format for desktop publishing. Color versions
are posted on the ISC home page:
Dr. Bill Castle, General and Scientific Tours Committee Chair,
has announced that a four-day tour of the Florida citrus industry
is planned for November 28-Dec. 1,2000. The tour will include
visits to the "ollo, ing regions: the "East Coast" of Florida, a
major fresh grapefruit production region characterized by
interesting soils, water management systems, and modern fresh
fruit packinghouses; the "Gulf Region," typified by large citrus
operations where oranges and other citrus are grown for
processed juice and fresh fruit markets; and the well-known
Ridge" of Central Florida, where orange, grapefruit. and
mandarin trees are grown on deep, sandy soils. Abbreviated
tours to the East Coast and Ridge areas will also be offered on
November 30-December 1, 2000
On December 6, 2000. half-day tours to a number of local
scientific and citrus industry sites will be conducted for Congress
participants. These tours will conclude at CREC, with tours of
our center available followed by a dinner,
A California delegation will organize a post-Congress tour if
there is sufficient interest. An alternate tour of the Mexican
citrus industry is another option.

FROM THE DIRECTOR.
During January. we hosted the first of two scientific teams who
are Xjisiping Florida to review citrus research programs of IFAS
and other institutions. The reviews have been requested b% the
citrus industry to evaluate how well the research institutions are
addressing the problems of Florida citrus and to develop some
planning for addressin, future needs, such as faculty
recruitment. The review crrocess will continue well into 1999.
and 'Ilt ultimately lead to some plans that should help IFAS and
the other agencies stay in synch with industry needs while
conducting quality science,
There were many people who participated in making the
peer review visit by the production team timely and
successful. First, to all .:; the faculr. who responded as
requested in providing a brief background on you position and
program accomplishments for inclusion in the written document
and for your participation in the site visit last month. This peer
visit was short notice and condensed, but was a success in large
part due to our participation. Thanks also to the smaller group
of CREC faculrt who prepared overview pieces for the
document de-cribing the broad issues related to citrus production
research. These discussions were e-mailed to all faculty upon
completion and were included in the printed document given to
the review team. Finally. I would like to acknowledge the
excellent assistance provided by some individuals who were
instrumental in getting the document together in time for the
review visit. Shelby Graham and Barbara Thompson spent
long hours producing the document, coordinating not only with
CREC Faculty, but with Department and other Center faculty,
and with USDA. ARS. They put the submissions .-aeher and
spent many extra hours .r,i:rin_ that the review team arrived
with some useful back2r.:.und information. Thanks also to
Monica Lewandowski and her group for assisting 5 he lb in the
local arrangements for lodging and on-site arrangements. Mike
Armstrong and Jamie Chastain provided computer access for
the team while at CREC, alio'A in' the team to generate a first
draft report before departing Florida. Thanks to all of you and
to others who [ haven't mentioned for your roles in making this
review process a success, Tne next phase is being scheduled, so
we will have a chance to do it all again
On another note, thanks to the Public Relations team for the
new look of the Citrus Leawes. Hopefull. you Ir,,d the new
leaves even more informaii .e and useful In an effort to make
the community at CREC more aware of events and group
activities, we have identified special columns which focus on
lopiL. such as student and personnel issues. For these to be
successful, you need to do our part to provide .nr[L'irrIaiIn, for
inclusion in the month\ issue. Please contact Monica
Lewandowski or Barbara Thompson with information for
inclusion or to offer suggesntons to improve your newsletter
