I've also read that milk is effective against powdery mildew. I've
had trouble with powdery mildew on my peonies for a couple of years,
and on a winterberry (ornamental deciduous holly) last year. So this
year I figured, "what have I got to lose", and tried spraying them
with milk. I even did a sort of slightly controlled experiment,
spraying some in the row of peonies and not others. I only got around
to doing it once, though.
The results were astonishing. The mildew stopped, and only started
growing again quite recently. All the plants look better than last
year. The unsprayed peonies also look better than last year, but
worse than the sprayed ones.
I wondered if it was just the weather. (a very damp cool summer. I'd
have thought it ideal for a fungus, but perhaps mildew needs warmer
weather?) But I've been looking at other peonies in the neighborhood,
and they seem to be as mildewed as mine were last year.
So I don't know about cucurbits. But I plan to spray my mildew
sensitive plants with milk again next year. Maybe I just got lucky.
But hey, milk is cheap and safe to use. What have I got to lose?
