Disease risk event from this Monday-Tuesday

I had a meeting and did not able to post it in timely manner, but there was a wet event on Monday-Tuesday this week.  It was 14+ hours of wetness and average was around 60F.  It was a risk event for downy mildew, and very low risk for Botrytis.

Other than a slight chance of rain tomorrow, it looks like we will have a nice cool week! 

For the late season spray recommendations, please refer to previous posts.
