Disease risks from today's rain

Thunderstorms went through Winchester area soon after the midnight (~12:35AM, 0.09 inches), and the relative humidity remained high (>90%) until 8:55AM.  Thus, we experienced an estimated wetness period of 8 h 20 min with an average temperature of 67F.  This event was long enough for Phomopsis, black rot, and downy mildew.  Boy, we have a lots of rain this year!
