Q.Yellowing Plants by Accident
I had made the mistake of putting down 2 different pesticides within a few days of each other, and now what were once hearty healthy zucchini, squash and pumpkin plants are now wilting and dying. Due to such recent heavy rains I had hoped that the pesticide would wash off or the plants would get enough water so that they wouldn’t wilt but it is not working. What do I do now? And can the plants be saved?
I think the key phrase is ''recent, heavy rains''. Squash and pumpkins need adequate moisture, but they don't like to be waterlogged. They are susceptible to fungus in hot humid weather. This article explains: https://www.gardeningknowhow.com/edible/vegetables/squash/tips-for-growing-squash.htm
