Allan I wish I had gone to that conference but it was just a day after our own Guelph Organic Conference. We worked with Dr. Elaine Ingham and used Aerobic Compost tea all last season. I removed copper from our vineyard spray program entirely. For 20+ acres we used less than 50 pounds of sulphur all season.
So what kept the mildew away ? this is Ontario not the arid west coast that Alan York it from. We have lots of powdery mildew AND we have something they don't in California - we have downey mildew.
