Powdery Mildew
I live in northern Canada and have had great luck growing a variety of pumpkin. For the first time this year, powdery mildew seems to have overtaken a number of my varieties. I tried to slow it with sulfur, but almost all of my leaves are dead. We are moving to a new property before next year and I was wondering how to go about preventing, eliminating this problem (chemically-organic or otherwise). I know to water early in the day and not get the leaves or stems wet much... and high sun and to eradicate infected leaves on first sight...
