It rained from 11 am yesterday at Winchester, and the rest of the day was wet (0.18 inches). It accounted for at least 13 hours of wetness (+ continuing today) with a mean temperature of 58F.

As you can imagine, even though the temperature was low, it was long enough for Phomopsis, black rot, downy mildew infection, and powdery mildew ascospore discharge.

We’ll have a meeting at White Hall vineyards today(6/5/09) from 11 am. I’ll talk about biology of major fungal diseases for VA wine grape using Powerpoint. The contents will be similar to the other talks, but you get to see more pictures. 😉 Tony will be there to talk about seasonal update as well.
