In Winchester area, rains from May 22-23 resulted in ~19 hours of wetness with an average temperature in lower 60's. We had 5-6 hours of dry period, then another rains went through the area, starting around 5PM last night. Relative humidity remained high (>90%) until around 5AM this morning, thus it was about 12 hours of wetness. Average temperature was again in low 60F. Both were infection events for Phomopsis and black rot. A total precipitation of the last three days was about 0.7 inches.
Also, in the last few days, night time temperatures were warm (in 60's) and relative humidity were high, thus, these could be downy mildew sporulation events as well.
I hope you and your family have a good holiday season and a Happy (and safe) New Year! Thanks again for your support of our programs. Here are some recent media highlights. 😉 The link will open a new window. AHS AREC promotional video that highlights some of our activities. The link did not work... It asks you to log in to VT. I will request the IT people to change the setting, but in a meantime, here's the same video. We also appeared in the Library of Congress project “Winery Workers of Virginia”. One more announcement: I will be moving this blog to a new location ( ext.grapepathology.org ) early next year. I had to make a change due to the email subscription service, which has been terminated. You do not need to change your bookmark or your email subscription. The URL will be forwarded to a new site and your email subscription has been moved to a new site already.
