Grape disease risks from the NEWA

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  (I reported to the NEWA, but I am not sure when/if they can fix it…)

Downy mildew risk forecast

We generated the downy mildew forecasted risk based on the past seven days and an 8-day weather forecast. Please click the figure below to enlarge. Some locations have high infection risks, but overall, we may have a bit of a break that we needed next week. The VA Wine Board and Southern Region Small Fruit Consortium have supported this effort.
