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 (which seemed to be more this week. I will report to the NEWA…)

Downy mildew risk forecast

In addition, we generated downy mildew forecasted risk based on the past seven days of weather and an 8-day forecast. Please click the figure below to enlarge. The rains from last week and forecasted rain events call for high-risk events in the next few days. This effort has been supported by the VA Wine Board and Southern Region Small Fruit Consortium.
