Here's the Peaceful Vallye write-up for Kaligreen, the version of 
potassium bicarb that has been recommended to us: Potassium 
bicarbonate for Powdery Mildew Kaligreen is a contact-type fungicide 
for the control of powdery mildew. It contains microencapsulated 
potassium bicarbonate as the active ingredient and direct contact 
with the fungus is absolutely necessary for control. Potassium ion 
balance in the fungus cell is broken by Kaligreen; cell walls 
collapse, shrinking the cells and destroying the fungus. Mix 
thoroughly with water and add a spreader-sticker and agitate. Do not 
mix with highly acidic materials since Kaligreen is a weak alkaline 
material and decomposes in highly acidic conditions. Labeled for over 
40 crops. Not for use through irrigation systems. Use at a rate of 
2.5-5 lb/acre. Pesticide I.D. # is required for California commercial 

About $40 for 5lbs, contrary to my earlier remarks -Allan
