A few weeks ago I noticed some mold spots on my grape vine leaves. I removed the bad leaves but was obviously too late, or the removal was ineffective. I now notice that my butternut squash leaves are dying too. They are about 20 yards apart. Coincidence? - I don't think so. I would like to use an organic remedy but if I have to go nuclear, I will!. I have attached 2 images of the grape vine leaves and 2 of the butternut squash.,
