Powdery gray fuzz on leaves, stems, flower petals, or fruit is a characteristic sign of this fungal disease, which is also called botrytis blight and botrytis fruit rot. Touching the infected tissue causes a little puff of spores to be released into the air. The fungus can attack a wide range of plants, but tomatoes, beans, raspberries, and strawberries are particularly vulnerable. Botrytis-infected flowers fail to open. Infected leaves drop off, and fruits rot. The fungus thrives in cool, moist conditions.
