Disease risks 7/12-14

An extensive wetness event was recorded on 7/12-13 (~30 hours) with a temperature range of upper 60F to lower 70F.  In addition, there was about 9 hours of wetness recorded in 7/14 with an average temperature of 70F.  Both were infection risk events for downy mildew and Botrytis (especially the long one in 7/12-13).  (These were infection events for black rot and Phomopsis, but berries should be resistant to black rot infection and Phomopsis is typically not active late in the season.)
