Without seeing a photo it's hard to know exactly what the issue is, Carolyn, but I suspect you have a case of powdery mildew, which is fairly common on cucumbers. Depending on how significant the problem is, you might start by spraying the leaves with baking soda (1 teaspoon in 1 quart water), which will raise the pH, creating an inhospitable environment for powdery mildew. If the condition worsens, you may have to resort to a fungicide. You'll find more from University of Illinois Extension here: http://urbanext.illinois.edu/hortanswers/detailproblem.cfm?PathogenID=139

I am beginning to combat this for the first time, on my peas and mint (and potentially beans). I did the baking soda last night and this morning, and it seems to have helped. but given how much there is (and how fast it came on), I saw on the UC Berkeley site that horticultural oil is the best thing to get rid of it. So I have some coming from Amazon, but meantime, baking soda seems like it will at least keep it from getting worse.

Carolyn, Safer makes an organic fungicide. I would use any of their products with confidence. Nancy, make sure you check the label on your horticultural oil for temperature restrictions before applying.
