I know this is early for this question but the answer might affect the way I plan out this years vegetable garden. Does anyone have an effective way to deal with powdery mildew on Cucumbers and Zucchini? I am looking into some of the fungicides that are advertised. I am considering moving all squash and cukes to one end of the garden so that I can spray if needed and not get it all over everything else. Last year it took my pumpkins, zucchini and my cucumbers in early august. Any help is appreciated. Thanks.
