Interesting article Jeff. I had some of what I suppose was powd. mildew in Chambourcin, Cabernet Sauvignon and Franc. In years past I did not have the problem. I routinely spray Nova/Mancozeb early and Nova/Captan late. The last spray, or perhaps 10 inches of rain followed by some warm weather, seemed to stop the problem. I wonder what "soft chemistry" is...any idea.

Soft chemistry usually refers to things like sulfur, biologicals, soap, oils, and the like
