Biology and Integrated Management of Fungi Affecting Tree Fruit Marketability (Methyl Bromide Alternatives)Entry ID: USDA0516
Abstract: The purpose of "Biology and Integrated Management of Fungi
Affecting Tree Fruit Marketability (Methyl Bromide
Alternatives)" is to develop alternatives to Methyl Bromide as a
soil fumigant, and decrease losses caused by post-harvest fungal
pathogens of tree fruit grown in the Pacific Northwest. Data
also provide information on the occurrence and control of
certain fruit-associated microorganisms ... that may either: 1)
limit export of U.S. apples to foreign countries, 2) decrease
desireability of fruit in domestic markets, or 3) pose a
phytosanitary risk to domestic fruit production.
This research evaluates biological control of post-harvest
fungal diseases of deciduous tree fruits by epiphytic
microorganisms. Post-harvested biocontrol using known agents
further developed including evaluation of application methods,
formulations, and larger-scale commercial testing.
Collection Organization: USDA Agricultural Research Service
Collection Methodology: Chemical control of deciduous tree fruit
disease entails evaluation of new fungicides for post-harvest
disease control, and evaluation of chlorine dioxide foam as an
environmental surface disinfestant for sanitation of fruit
handling surfaces. The etiology, taxonomy, and ecology of fungi
associated with cherry fruit will be determined to develop more
effective post-harvest disease control measures, including
biological control. Biologically-based alternatives to Methyl
Bromide as a soil fumigant will be developed for the effective
management of soil-borne pests, including plant pathogens and
nematodes, for fruit trees.
Collection Frequency: Ongoing research.
Update Characteristics: Ongoing.
