My two zucchini plants have white stuff on the leaves and the zucchinis are forming, but then shriveling up and falling off before becoming mature.  I primarily water with a water soaker, so the leaves are not receiving a lot of water.  I would like suggestios on how to treat this naturally as I want to eat the zucchini we produce and not worry about toxic chemicals, etc.  Any suggestions are appreciated!

Powdery mildew is common--my plants almost always get it eventually, but it doesn't always compromise yield. A very common cause of zucchini failing to mature is pollination failure, especially now that bee populations are dwindling. It can be solved simply with an artist's paint brush. Dab it in the center of the male flower (long stem, no baby zucchini) and then in the center of the female flower. That may solve your shriveled zucchini problem. Same goes for other types of squash.

Milk will alter the pH of the leaf surface, so that any displaced mildew spores will not be able to take root. I use this mixture to spray the entire plant every day until the problem is solved (usually a week or two). I use plain chamomile tea in place of water once a week as a preventative.

Check with the local extension office for their recommendations for your local area; here ia a link for information about powdery mildew. It gives some non-toxic remedies that are available even if you don't live in California. http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7406.html
