Does Neem Oil Cure Powdery Mildew?
Some of my squash leaves have powdery mildew. It's not so bad that the entire leaf is white but there are definitely white spots here and there. How serious is powdery mildew and can Neem Oil cure it rather than just prevent it?
I have been spraying Neem once a week for bugs so I was surprised by the powdery mildew. It's mostly on the lower leaves that are shaded.
