Ed Rosenthal 's Zero Tolerance Herbal Fungicide eliminates Powdery Mildew, Gray & White Mold, Black Spot, and most molds and fungi.
Ed blends several herbal oils into a natural fungicide that knocks out spores quickly. He adds potassium bicarbonate to changes the pH of the leaf surface to the alkaline side, which stops the growth of new spores. The herbal oils evaporate fully so ZT can be used within a week of harvest. Ed 's Zero Tolerance is 100% Vegan and even smells good.
Powdery mildew is a widespread plant disorder that spreads quickly. Sometimes it can be controlled by raising temperatures to over 90Âº — at other times you just have to spray.
