Here are links to the 2021 edition of Pest Management Guides. Unlike the past years, all the crops are combined together. (i.e., I cannot separate the grape section.) Once you get to the site, click "PDF", then "Preview", and it will open a new window. Then you need to click "Download Version" to download the file to your computer. Once the document is downloaded, you can search the document to find "grapes".
Winchester area received precipitations from thunderstorms yesterday. It started around 3:30PM and lasted until 7:00PM. The actual amount of precipitation was not high (0.05 in) compared with other northern VA regions where a severe thunderstorm warning was issued, but since the ending part of the thunderstorm hit during the evening, the relative humidity was high (>90%) until 2 AM or so. Thus, it accounted for 11.5 hours of wetness with the average temperature of 73F. It was warm and long enough for Phomopsis, black rot, and downy mildew. We are still having chances of rain (40-60%) until Monday.
A bit confusing but I got it.
