Winchester area received a series of thunderstorms from 3:00 PM yesterday, and relative humidity remained high (>90%) until 9:00 AM this morning. Thus we had a wetness event of 18 hours with an average temperature of 66-67F. It was warm and long enough for Phomopsis, black rot, downy mildew, and Botrytis infection.
