Gray mold, caused by the fungus Botrytis cinerea, is a disease of many crop species. It can be a serious problem for the strawberry grower, especially in the Northeast where cool, damp spring weather is ideal for disease development. Disease can strike at any time during the growing season when weather conditions are right. Gray mold can cause significant crop loss both pre- and post-harvest. Disease Cycle The fungus overwinters in plant debris. In spring, it produces spores that are dispersed by wind and rain splash. These spores germinate and can infect blossoms and leaves.
