I've had luck with water & milk, 50:50 against powdery mildew. it lives in the soil too. just a few applications and you'll see an improvement. why let it spread?

I forgot to say, leave the milk out overnight. it's those bacteria that eat/fight/kill the PW... or so I've been told. I guess my battle with it has gotten better over time. just now realizing that. it was a few years ago that I had it bad. last couple of years, there has been any, and we had a cool wet summer in central ny.
