After 13+ hours of wetness on the 13th-14th rain event, we had another wetness event starting from last night.  It resulted in 11 hours of wetness with an average temperature near 70F.  It was infection event for downy mildew, black rot, Phomopsis and Botrytis. 

With the back to back rain event and high humidity during the night, I would keep eyes on downy mildew development.  It tends to show up on younger leaves (at the top of the canopy) first.  Also, many of varieties are about to be berry-touch/bunch closure stage, which is one of timings for Botrytis application.
