Fungal Resistance Management Videos

Much of the wine grape pathology research we have conducted in Georgia over the last 2-3 years has been associated with resistance management of fungal pathogens such as downy mildew, powdery mildew, Botrytis and others. Alternation or tank-mixing of different fungicide classes is critical for prevention of resistance development. Under the direction of Dr. Walt Mahaffee (USDA; Corvallis, OR), a video has been developed by Dr. Madeline Downing (Clemson University) to fully explain how resistance develops. This short, highly educational video would be worth your review, and there is also a Spanish version available. Links to the video can be found at the Fungicide Resistance Assessment, Mitigation and Extension Network (FRAME) website via the following link:
