Jerry A. Bartz

Associate Professor (80% Research, 20% Teaching)

University of Wisconsin, B.S. 1964, M.S. 1966, Ph.D. 1968.

Employment:

Post Doctorate University of CA., Riverside 11 /68 - 10/69
Assistant Professor University of Florida, 1969 - 1974
Associate Professor University of Florida 1975 - present
Visiting Assoc. Professor University of Wisconsin

Responsibilities:

Research: Postharvest diseases/ bacterial soft rot.

Teachinq: PLP 5103, Theory and practice of plant disease control; PLP 3103, Plant Disease Control (taught concurrently, second semester of odd years); PLP 6921, Plant Pathology Colloquium and PLP 6932, Plant Pathology Seminar (taught as requested by Dept. Chair).

Extension: No formal assignment but have provided presentations at extension functions and have provided advice to industry when requested.

Major Accomplishments:

Provide leadership in the control of postharvest diseases of tomatoes, peppers, strawberries, potatoes, and other vegetable crops. Helped to form a postharvest group at U of F that is composed of two horticulturists, one pathologist (myself), and two agricul tural engineers. Also, if food borne infections are involved, the postharvest group can include up to three food microbiologists. We address all aspects of postharvest handling and storage. Thus, industry and granting agencies concerned with the postharvest qualiity of perishable produce can contact one person of the group who will involve the oth ers as the need arises. This greatly shortens our response to the concern. Personal accomplishments include elucidation of the dangers of infiltration of fresh produce with dump tank, flume or wash water; improvements in the sanitation of dump tanks and flumes with chlorinated water; and determination that tendency to absorb water in tomatoes is an inherited characteristic.

Honors and Awards: Co-recipient of the "Council Memorial Tomato Research Award" given by the Florida State Horticultural Society on October 30, 1991 for the development of "Solar Set: a heat tolerant fresh market tomato hybrid."

Professional Activities: Currently, Chair of the Postharvest Pathology Committee of the International Society of Plant Pathology . Previously, Senior Editor of "Plant Disease " 1987 - 1991; Member the Postharvest and Mycotoxicology Committee of the American Phytopathological Society, 1974-1978, and 1988-1991, Chair of committee, 1976-77. Member of the Technical Committee of Regional Research Project NE-87, 1979-1992. Member-at-Large 1980-82, Secretary 1982-84, and Chair 1984-86. As Chair, l wrote a project revision. The revision was accepted for the 5-yr period 1987-92. Vice-Chair, Organizing Committee of the Symposium on Postharvest Pathology and Mycotoxicology for the Sixth International Congress of Plant Pathology held at Montreal, Canada, 1992-93. Co-Chair, Symposium "Risks and Challenges in Food Safety and Storage" held at the Sixth International Congress. President, Florida Phytopathological Society, 1989-91. Organized with C. S. Barfield a discussion session "Classroom teaching of integrated pest management." for the Second National Integrated Pest Management Symposium/Workshop, Las Vegas, Nevada, 1994.

Creative works

Co-developer of five tomato cultivars: Florida MH-1 (the first jointless tomato cultivar for machine harvest); Floramerica (a large-fruited, high quality tomato developed for the home gardener) (This cultivar was entered into the "All-America Vegetable Variety Trials and grown at 21 different locations in North America. It received the Bronze award based on its average performance in the test locations.); Calypso (a tomato cultivar suitable for the Caribbean climate); Solar Set (Solar Set was the first large-fruited cultivar that combined an ability to set fruit under night temperatures >21°C along with the yield, fruit quality, and fruit size required by the fresh market tomato industry.); and Equinox (An improved "hot-set" hybrid that produces higher yields of larger and smoother fruit than Solar Set.)
