I use my blog to communicate seasonal (and off-season) disease management information to growers. Also, please check “resources”, which is listed on the right-hand side of the screen. I have listed several extension-related materials that you may find useful. (The list may show up at the bottom if you use your phone or tablet.) If you prefer to receive a notice when I post, you can subscribe to my blog by entering your email address.
Also, my program is a part of the Sentinel Vineyard Project where we gather information on viticulture and enology directly from growers to be used in our extension effort.
