Disease risks from yesterday’s rain and some rains in the forecast

Well, I almost missed it, but we (Winchester area) had a short rain event started from Saturday night around 11:20 PM, lasted until 12:00 AM or so Sunday.  Although it was not a major rain event, it started late at night and the relative humidity was high (>90%) until 8:20AM (=9 hours of wetness event), with an average temperature of around 68F.  Thus, it was warm and long enough for both downy mildew and Botrytis.  Since it has been so dry that it may not have much impact, but it is worth noting.

We are expecting some chance of rain (30-40%) from tomorrow to Friday.  I’m not sure how much of these chances become real, but we need some rain…

Our meeting is coming this Wednesday!  I hope you can make it.
