Botrytis rot, or gray mold as it is often called, is a serious disease in all strawberry production areas and is a disease of concern in most years. The disease is a problem not only in the field, but also during storage, transit, and marketing of strawberry fruit, due to onset of severe rot as the fruits begin to ripen. Other parts infected by the fungus include leaves, crown, petals, flower stalks, and fruit caps. Crown rot is discussed elsewhere. Disease is most severe during bloom and harvest in seasons with lengthy periods of cloud and rain complemented by cool temperatures.
