Powdery Mildew on Pumpkins

[TheDarkSide]

Last night I was watering my pumpkins and noticed a white, powdery substance on my pumpkin leaves. I'm assuming it's powdery mildew since it's been pretty humid here lately. I was reading up on it and see that some people spray them with a milk/water solution because the low ph of milk kills the mildew.

So I was wondering if Star San would be a good solution to this because of it's low PH? Anyone use Star San on their plants to control this stuff? I know some will pour their spent Star San on their flowers as a fertilizer, but I'm not sure if 12ppm Star San is harmfuil.

I had a spray bottle of SS so I sprayed a couple plants this morning to see what would happen.

Neem Oil is what we're using to fight the powdery mildew. It fights that, a few other diseases, and many pests. I didn't try Star San; Neem Oil seems to be working pretty well though. Right now we're spraying it after the sun goes down, once a week or every two. Last year we lost lots of plants to the mildew (we're both newbie gardeners); this year we're fighting hard!!
