Help!! What killed my pumpkin?? My plants were fine and then three days later I went to the garden (is in a community garden) and the leaves had turned yellow and then brown and was all wilted. I could tell it wasn't going to live. Then a few days later another pumpkin plants' leaves are turning yellow and are wilting.

We have had extremely hot temps for almost a week but I have watered them well. I also use soaker hoses so water rarely gets on the leaves. I have been very faithful in spraying for bugs (Tempo II) and have not seen any of the usual culprits. When I planted them at the end of May I sprinkled a three-month all purpose fertilizer in each hole and have sprayed the leaves with kelp spray a few times.

I am pretty sure it is a virus-type of problem but which one? Anything I can do to keep it from spreading to the others? Will I be able to use this same plot next year?
