Spotting Anthracnose and Downy Mildew Quickly
Dr. Dean Volenberg from Door County Wisconsin is back this summer with his excellent “Vineyard IPM Scouting Reports.” The link below will take you to some very revealing photos of Anthacnose and Downy Mildew. (Some of the photos are quite graphic and squeamish viewers are advised to look cautiously.)
Dr. Volenberg reports that the Wisconsin Grape Growers Educational Committee Survey that found pest identification was the most important topic of survey respondents.
