Does milk solution work for Powdery Mildew on Squash?

June 13, 2008

Happy Friday the 13th.

I woke up today to find white PM spots all over my sunburst (yellow) squash and cukes, and possibly my zucchini.

I was overwatering them, I'm sure. :-) The weather here has been perfect for them and they haven't been thriving. THey're in full sun from about 9 am to 5 pm and temps from 85-95.

So... I've seen differing reports about the milk solution, and none of my local nurseries know anything about it.

I've seen a lot of the older posts, right when the first few studies came out about milk, and I'm wondering what the consensus now is. Does it work? I've seen the 10% and 50% milk quoted. I've also seen that it's only for prevention and others say it works for treatment as well.

Any help?

Should I just yank them and start over from seed? (Here it'll stay hot until October, probably, so I do have a nice long growing season.)
