INTRODUCTION
On behalf of the faculty and staff, I extend to each of you a most cordial
welcome to the Agricultural Research and Education Center at Bradenton.
This Center was initiated in 1925 as a one-man tomato research operation
in Palmetto and the first ornamental programs began about 17 years later.
This Center, with affiliated Agricultural Research Centers located in Dover
and Immokalee, Florida, is a Research and Education unit of the University
of Florida's Institute of Food and Agricultural Sciences.
In Bradenton we have 12 research scientists from various disciplines of
training who participate in ornamental plant research programs. Each
research scientist also holds an affiliate appointment with his subject matter
department at the University of Florida. This combination of a broad base
of research disciplines, industry contacts, and an excellent faculty makes
our interdisciplinary cooperative team approach to research programs far
more productive than could otherwise be accomplished with limited invest-
ment in independent programs.
An integral part of the overall mission of this Center deals directly with
the ornamental industries in Florida through research programs to (1) Develop
new or improve technology for more efficient production, handling and
utilization of ornamental crops; (2) Improve quality of products made avail-
able to the public; (3) Develop technology and practices to reduce both
energy consumption and environmental pollution without sacrificing quality
during production and thereby enhance man's environment; (4) Maintain and
improve the productivity of soils in the state of Florida; (5) Develop
improved technology on uses of ground water resources, solar energy and
energy conservation practices in greenhouse and agricultural production;
(6) Develop information for all Florida growers to compete effectively
with other geographic areas of the nation and world; (7) Advance basic
knowledge of the various scientific disciplines represented by the faculty;
and (8) Assist the cooperative extension service, departments in the College
of Agriculture and other Research Centers with extension, educational
training, and cooperative research programs for the benefit of producers,
consumers and students.
Information presented in this publication summarizes the active research
projects under way this season. We sincerely appreciate your interest and
support of these research programs and continuously solicit your suggestions
for improvement and ideas of industry needs from our research and extension
programs.
Will Waters, Center Director
HISTORY OF THE AGRICULTURAL RESEARCH & EDUCATION CENTER BRADENTON
Agricultural Research & Education Center Bradenton originated in the fall
of 1925 with the construction of the Tomato Disease Laboratory.
Tomato Disease Laboratory: In 1925 a 20-acre tract of county-owned property
in Palmetto was made available with the cooperation of the Manatee Board of
County Commissioners, with money and equipment supplied by local growers.
Primary objective of the laboratory was to formulate a control of nailhead
spot of tomato. Later studies emphasized the breeding for resistance to
Fusarium wilt and the control of tobacco mosaic on tomatoes. In 1937,
with the expansion of the vegetable industry in Manatee County and
surrounding areas, the State Legislature authorized new facilities for
the research program.
Vegetable Crops Laboratory: In August, 1938, the Manatee County Commissioners
donated eighty percent of the purchase prive of a 106-acre tract on the east
side of Bradenton. This expanded program led to the establishment of the
Vegetable Crops Laboratory. Following this relocation, horticultural
entomological, and soil studies were initiated on tomatoes, peppers,
lettuce, sweet corn, and other vegetables. Since the laboratory was located
in the gladiolus growing area, the scope was further broadened in 1942 to
include disease problems confronting gladiolus growers.
Gulf Coast Experiment Station: In March, 1951, at a meeting of the State
Board of Control, the Vegetable Crops Laboratory was given the status of a
branch station and was renamed the Gulf Coast Experiment Station.
Investigations were then initiated dealing with chemical weed control,
nematodes, and other soil-borne pests. The ornamental phase was broadened
to include chrysanthemums and other commercial cut-flowers.
In the late 1950's it became apparent that the facilities on the outskirts
of Bradenton were no longer adequate for the research program. In 1959 a
200-acre tract was acquired 8 miles east of Bradenton. All of the vegetable
experimental field programs were moved to this new location.
In 1965, upon completion of the construction of office and laboratory facilities,
farm buildings, greenhouses, and a residence, all research programs were
conducted on this new land.
Agricultural Research & Education Center Bradenton: In 1971 the Gulf
Coast Experiment Station was renamed Agricultural Research & Education
Center to emphasize the programs of both research and education.
Active programs are in progress on production problems associated with
vegetables and ornamentals grown on the sandy soils of Florida.
AREC-Bradenton has administrative and research supervision over two satellite
stations: ARC-Immokalee (formerly the South Florida Field Laboratory) and
ARC-Dover (formerly the Strawberry and Vegetable Field Laboratory). The
former center specializes in vegetable nutrition and culture, etiology and
control of diseases, and pasture research while the latter is the hub of
strawberry research in Florida, including breeding, horticultural, and
pathological studies.

Botrytis and Cercospora on statice are potentially
destructive diseases during the fall and winter seasons.
Botrytis disease may severely blight flowers while
Cercospora ('frogeye' or blight) leaf spot may defoliate
badly infected plants. Treatments are being evaluated
for their ability to effectively control Botrytis and
Cercospora diseases on two susceptible statice cultivars
('Midnite Blue' and 'Roselight').

Botrytis blight is potentially one of the most serious diseases
facing geranium growers during cooler weather. The 15 chemical
treatments in this experiment are being evaluated and compared
for disease control and phytotoxicity. Also, 10 cultivars are

High concentration, short duration exposures to airborne
SO2 are more damaging than the same dosage administered
at a low concentration over a longer duration. Exposure
when stomates are open is more damaging as in the
morning, with sunlight, adequate soil moisture and high
humidity. Fluoride toxicity effects are cumulative
in that long exposure to low concentrations are damaging
due to translocation and accumulation in limited areas
of leaves such as the margins and tips. Specific plant
response information is to be used to select plantings
that will tolerate ambient air pollution. Also, the
potential for improving air quality with plants,
especially trees, is to be stressed.
