Disease risks from 27-28th

July 27-28th were very wet for us.  We recoded two long wetness events (8 hours and 22 hours), which were infection events for Botrytis, downy mildew, black rot, and Phomopsis.  In addition, we had a short rain event that were long enough to be considered as downy mildew infection event.

Our major concern would be Botrytis on fruits and downy mildew on leaves.  Please make sure to have protection on clusters against Botrytis.  We do not have any fungicides that work after infection takes place.
