Jan-Feb 2010 Viticulture Notes

2010 January - February issue of Viticulture Notes is published. There is a section of grape pathology too. Viticulture Notes and other seasonal information is distributed from our viticulturist Dr. Tony Wolf through the email. If you have not been subscribing to Tony's email list, please let me know so that we can add your name to the list.

Since out website is in the process of renovation, this issue of Viticulture Notes has not been uploaded yet. In the mean time, I uploaded here for your convenience.

I just came back from a meeting in Tennessee where I was invited to give talks about grape disease management (Tennessee Horticultural Expo). I had a good time meeting with new people. Tennessee's wine industry is smaller than that of ours, but it's growing strong. I hope we can continue communicating each other because we share similar growing conditions, especially in the southern VA and eastern TN.

    Dr. Nita,
    I had the pleasure of attending one of your sessions in Nashville at the Horticultural conference. I found your session to be very informative; much so I'm now for the first time trying to develope my own spray schedule using your spray guide lines and notes as an example.

    One problem I'm having is locating suppliers of some products; esp the Phosphorous and Potassium salts. Are you aware of any good retail sources? My area of coverage is very small (less than 1 acre).

    Thanks!

    Pat

    Hi Pat,
    Since you are dealing with small area, you may want to try local retail stores such as Southern States, or local co-op. They may carry chemicals in small quantity. Also, if you take a look at the table for home garden materials (a link is on your right), a company Monterey (http://www.montereylawngarden.com/) is supplying Agri-Fos and Bi-Carb which are Phosphorous acid and Potassium bicarbonate, respectively. You should able to find them in one of stores or in their on-line stores.

    Good luck with your up-coming season!
    Mizuho

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...

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.
