We have planted zucchini plants and they look healthy and are growing, but then all at once they start to wilt until they die. What kind a problem do we have? They did this last year too, and we lost all our zucchinis. The plants look healthy and grow good. We also check them for pests and use Sevin 7 or Sevin 10 on them. Please help. We have one dying now, and we do not want to lose the rest of them.
