We’ve noticed that several of the leaves on the zucchini plant are covered with a fine, white powdery substance.  I’m probably not going too far out on a limb to conclude that it is powdery mildew.  We’ve seen it before (last year) and although it looked bad, it didn’t seem to have much effect on the plant’s production.

But here’s something we haven’t seen before:  One of the zucchini squashes has turned black and hairy, an extremely unattractive condition for a zucchini.  It is right next to a perfectly healthy one so whatever it is, it is localized.  We quickly lopped it off with the garden clippers and tossed it away.  I’m not sure whether it is a symptom of powdery mildew and hopefully it won’t spread.
