Goals / Objectives
The goal of this research is to develop postharvest programs that can be integrated into existing postharvest handling practices to control Mucor rot and gray mold, two emerging postharvest diseases on mandarin fruit. Specific objectives include: (1) To determine fungicide resistance profiles for Botrytis cinerea isolates from mandarin fruit, (2) To evaluate and develop postharvest practices consisting of sanitizing agents, salts, hot water, and fungicides for control of Mucor rot on citrus fruit, and (3) To evaluate and develop postharvest practices consisting of sanitizing agents, salts, hot water, and fungicides for control of gray mold on citrus fruit.
Project Methods
Resistance to citrus postharvest fungicides in Botrytis cinerea isolates from mandarins will be tested. Fungicide-resistant phenotypes will then be determined and used for guiding the development of postharvest practices for control of gray mold caused by B. cinerea. Integrated approaches consisting of sanitizing agents, salts, hot water, and fungicides for control of Mucor rot caused by M. piriformis and gray mold on mandarin fruit will be evaluated in the laboratory and under semi-commercial conditions.
