Lots of rain in Wisconsin so far this week. I have had nearly 3 inches in my backyard in Madison, but not a drop in Sampson at the vineyard. I'm sure all of the rain will come the two weeks just before I am ready to pick .... the worst possible time.
We are getting a lot of heat and humidity. I may hit the vines with some Armicarb this weekend. (Armicarb is an potassium carbonate based Organic approved fungicide to kill powdery mildew and blackrot.)
