Winchester area received a shower yesterday, resulted in 5+ hours of wetness in lower 70F. It was an infection risk event for downy mildew, and very low infection risk event for Botrytis. In addition, we observed dews in the last two nights, indicating high humidity, which can trigger downy mildew to produce spores. As usual, late season downy tends to appear on younger leaves on the top of the canopy. Please keep eyes on them! There is a chance of rain on Sunday and Monday.
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.
