I thought that only worked on pests. I'll definitely have to look into it. So you have to reapply regularly?

It's safe to apply whenever needed, but with as good as it works, I only needed to apply it twice over a week's span to totally eliminate the powdery mildew. I did catch it early before it got really bad and within a week it was gone. When I use it for pest control I only use it when I actually see the bugs.
