Mold on Zucchini, Squash and Cucumber Leaves

Anonymous added on August 1, 2011 | Answered

White mold is on the zucchini plant and is spreading onto my squash and cucumber leaves. I cut the affected leaves and after any rain the mold is still spreading. If I keep cutting the leaves, all that will be left are the vines and whatever vegetable that has grown (zucchini, squash and cucumber). The tomatoes seem to be ok but the leaves and branches are turning yellow. The mold seems to keep away from the bell peppers, eggplant and beans.
