Hi there!
I've tried the cornmeal on the ground and Garrett Juice and bicarbonate on the leaves, but the pumpkin leaves still have the powdery stuff and yellowing and brown edges on them. The brown may be from the orange oil sprayed on there for pests but the other just won't be controlled. What do I do?

I've read that you can use a 1:10 solution of milk:water to control powdery mildew, but I have not tried it. The premise is that the lactobacillus in the milk keeps the mildew under control. I guess if nothing else is working, it won't hurt to try.

Try the garlic tea spray. There is a commercial product available now that is labeled specifically for powdery mildew.
