Zero tol didn’t help me nor did oxidase… 2 tablespoons of potassium bicarbonate mix with 2 tablespoons of Spinosad added to 1 gallon of water works perfect… I see no more signs of powdery mildew, but that doesn’t mean it isn’t working somewhere in my garden. I will continue to do preventative maintenance with it once every few weeks just in case, because when those spores start to be visible, it’s almost too late.
