Maybe you don't need the vinegar,

"An alternative nontoxic control for mildew is baking soda combined with a lightweight horticultural oil. Researchers at the University of Rhode Island have confirmed that a combination of 1 tablespoon baking soda plus 2.5 tablespoons oil in 1 gallon of water is effective against powdery mildew on roses. Use of this combination on other crops is still experimental."

HeadSpace Reviewed by HeadSpace on . Powdery Mildew prevention help. hey fellas, I need a recommendation for a powdery mildew cure or prevention. I need something that is ok to use in the beginning stages of flowering, buds arent that big but they are there and i dont want to hurt them. I bought some neem oil spray, but i just found someone on a forum saying that neem oil is not good to use on flowering plants. Is this really true, particularly for the early stage? I'd really appreciate if someone can chime in with some experience. Need to figure this Rating: 5
