When it was new on the scene here in the 70's i think, that is what it was recommended for as it repels cucumber beetles for some time. These are a bad pest here, and they spread bacterial diseases and mildew as well as munching the hell out of them. Anyway, neem is a wonderful botanical with many uses. Here is a thread where gardeners talk about using it on powdery mildew in squash and cukes: http://www.helpfulgardener.com/phpBB2/viewtopic.php?t=14348 Mon, 29 Jun 2009 13:10:43 GMT http://greenthumbs.tribe.net/thread/96533d17-adf2-4864-88c0-a673472ee0ca#07bbf8e1-2585-460f-a789-1300ef7b2530 wil 2009-06-29T13:10:43Z http://greenthumbs.tribe.net/thread/96533d17-adf2-4864-88c0-a673472ee0ca#867aabdf-22ed-41b4-a6b4-01abe2e7510b last year i had this on the zuke leaves, they are cousins. . .people said water only in the morning to prevent that. . .it was too late then, but soon i will be seeding again. . .we'll see. .

Here is a good page on powdery mildew: http://www.ext.colostate.edu/pubs/garden/02902.html and the wikipedia entry for neem oil uses: http://en.wikipedia.org/wiki/Neem_oil#Uses Sun, 28 Jun 2009 21:49:14 GMT http://greenthumbs.tribe.net/thread/96533d17-adf2-4864-88c0-a673472ee0ca#60fbda75-5e3b-4e27-9ba6-5cec6abb87a8 wil 2009-06-28T21:49:14Z http://greenthumbs.tribe.net/thread/96533d17-adf2-4864-88c0-a673472ee0ca#20c0af9c-2858-42ea-8d1a-598a70969c56 Could be powdery mildew....starts as whites spots on the underside of leaves but eventually covers the entire leaf with powdery areas.... There is a possibility that you can control it with a baking soda spray applied once a week: 1 teaspoon baking soda to 1 quart water. Note though that if you can't control it it will spread to other plants. The most common solution is to thin your plants, remove and destroy all infected parts, disinfect your hands and tools in a bleach solution: 1 part bleach 4 parts water after each cut. In addition to pruning: apply a cooper based fungicide every 7 to 10 days (stop 3 to 4 weeks before harvest). As for NEEM it is used on insects and works as a repellent and insecticide.

Yeah, neem is what i'd use. Use it in the evening so the hot Sun doesn't hit leaves fresh sprayed. Water them well, then spray.

I am assuming it is a fungus. Would neem work?
