Disease risk events from the weekend
As we expected, Winchester area had a wet weekend. We had to major rain events, which resulted in 11 hours and 10 hours of wetness, both are in upper 60F to lower 70F range. These are downy mildew and Botrytis risk events. Once again, humid nights we are experience can be a precursor event for downy mildew risk events because these nights favors spore production of downy mildew pathogen.
