Research Project: Management of Postharvest Diseases of Fresh Fruits

Location: Commodity Protection and Quality Research

Project Number: 2034-43000-039-06-A
Project Type: Cooperative Agreement

Start Date: Sep 30, 2015
End Date: Apr 30, 2019

The objectives of this cooperative research project are to determine fungicide-resistant phenotypes in the fungal pathogen Botrytis cinerea from table grapes and to evaluate new alternatives for control of postharvest gray mold caused by Botrytis cinerea on table grapes.

Resistance of isolates of Botrytis cinerea to selected fungicides will be determined using fungicide-amended media assays or molecular approaches. The information will be used for development of disease control programs. Laboratory and cold storage experiments will be conducted to evaluate new alternatives or new methods to apply postharvest treatments for control of gray mold on table grapes.
