The rain on the 29th was a very short one, but it was enough to make leaves wet for about 10 hours and the average temperature was higher 60F. It was infection event for downy, black rot, and Phomopsis. The rain on the 30th was too short for any infection.
Once again, the current condition favors development of downy mildew and black rot. Please do not let something like the picture below happen to you! (Downy mildew on a cluster, taken from our downy mildew trial.)
