Research interest:
Botrytis cinerea, one of the most important plant-pathogenic fungi, is responsible for gray mold diseases on more than 230 plant species worldwide, including strawberry crops. Substantial economic losses resulting from diseases caused by B. cinerea occur not only during the crop growing season but also after harvest, during storage and transit of agricultural products. Control of gray mold diseases caused by B. cinerea is largely dependent on the use of synthetic fungicides. However, B. cinerea is a classical “high-risk” fungal pathogen in the development of resistance to fungicides because of its high genetic variability, short life cycle, and prolific reproduction. Resistance of B. cinerea to several classes of fungicides has been frequently reported worldwide, resulting in the failure of disease control. The goal of my research project is to develop a resistance profile monitoring kit as a tool to rapidly determine location-specific fungicide resistance profiles in B. cinerea on strawberry plants. The information obtained will enable commercial growers to optimize their spray program for more effective gray mold disease control and fungicide resistance management.
