Disease risks from the weekend

It did not rain much at my place (about 10 miles East of the station), so, it did not register to my mind, but Winchester area received a series of thunderstorms on Sunday night.  It stared rain around 10AM and an estimated leaf wetness period was 10 hours with an average temperature of 64F.  It was a risk event for Phomopsis, black rot, downy mildew, and Botrytis.
