Here are snapshots from the last week, showing the number of days with the risk of each disease: Ph = Phomopsis, PW = Powdery mildew, BR = Black rot, and DM = Downy mildew. N/A means there is no data or some issues with the NEWA (which has been reported).

It seems that the majority of the state is still on the drier side. However, please note that northern VA and southeastern VA have experienced several days with downy mildew risks in the past two weeks.

For early-season disease management tips, please see the post here or the slides from the previous online meeting. 

The next Virtual Viticulture Meeting will be on 5/8 from 1 PM.
