I'm sure one of the reasons Alan York has never seen anyone radionics is that I have never heard of anyone on the North Coast of California (Napa, Sonoma, Mendocino) who is even playing with radionics. If there is any here using radionics, they are keeping pretty quiet.
And sulfer is a way of life out here. Every 10 to 14 days from flowering through veraison. Powdery mildew is a big problem and sulfer is the only Organic method that works reliably. Peter
