The following message is from Brooke Warres, a graduate student in the University of Georgia Plant Pathology Department.
“Now that we are at harvest and spray programs may be halted or reduced, powdery mildew will likely be popping up. As mentioned previously, we are conducting a survey of fungicide resistance in powdery mildew. We are trying to sample as many vineyards as possible to determine resistance profiles for DMI (e.g. Rally) and QoI (e.g. Abound) fungicides; the derived resistance information will be relayed to each participant — allowing more efficacious fungicide selection for next year. If you observe powdery mildew, even if it’s a small amount, please contact your local county agent and/or email me at Brooke.Warres@uga.edu or call me at 678-642-2183. Either your county agent or I will come by and quickly swab the leaves that have powdery mildew on them. Thank you so much for your help!”
