Bud swell 2012


Two weeks of 80's and 70's surely moved things forward.  When I checked our Chardonnay buds last week, it was swelling, but was still tight, but now it looks like they are ready to go at any moment. (Note: these are 4-yr old young vines.  Also, sorry for out of focus pictures.  I forgot to take my camera with me yesterday.)

Hopefully, it will go well with a longer than usual growing season, and we end up having early harvest this year!!

The first disease to be concerned is, as usual, Phomopsis.  The best management strategy against Phomopsis is use of a protective fungicide such as mancozeb or captan, since we do not have any material with curative activity.

Also, since we had a warm dry early summer before Irene, many of us saw quite a bit of powdery mildew.  Chances are, we have a plenty of inoculum.  Although we do not typically see powdery mildew until later in the season, with this warm winter, I am not sure what will happen.  I know it is not the best IPM practice, but with given conditions, I think it is a good practice to tank-mix mancozeb with sulfur (2-3 lb/A) to have some insurance against early season powdery mildew.

Season's Greetings!

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.

Downy mildew gallery

At Winchester, we had light rain events during the night of 6/12/09, but it was short events and the relative humidity was low (80% or so), thus it probably did not promote any infections. However, we are experiencing continuing favorable nights for downy mildew sporulation (average T>55F, high RH (80-100%)) for 10 days now. Yesterday, we conducted a formal disease assessment, and observed first incidence of powdery mildew for this season. We had plenty of infection events in last two months, so it was not surprising. At this point, it is a trace level of infection on untreated vines. Downy mildew was the major disease so far. We had up to 40% incidence on untreated vines. Next runner-up was black rot. It varies vine to vine, but some of vine had 10-15% incidence. Phomopsis was omnipresent as I expected from early May rain falls, but severity was low overall. We will examine diseases again in the near future, and I will update as the season goes. Here is downy mildew ga
