White stuff on Zucchini Leaves

I'm a beginner suburban gardener with a small patch of tomatoes and zucchini in my backyard. I'm also a relatively new member of GardenWeb and this is my first posting to the forum.

I've had this white stuff appearing on the leaves of my zucchini plants. The zucchini's themselves seem fine, and the leaves don't seem to be harmed by it either. I didn't notice anything on the stalks or flowers. The white stuff is on a lot of the leaves but not all. It looks as if the plants are dusted with powder.

Anyone know what this is? Should I be worried about it? What should I do about it?

A lot of people around here have had tomato blight, but my tomatoes are fine. This is only on the zucchini which I started indoors from seeds myself.

Thanks for any help you can offer,

Mary.
