Last one for tonight...
Who knows anything about powderly mildew? Where does it come from?
From the time my fruit went down, I slacked off on everything in the patch.
By now it looks like there's been a snow storm, the powdery mildew is so
thick! As I tear out the plant, the dust from it flies all over the place.
Are those spores going to survive in the soil? Can I do anything now to
minimize its reappearance next year?
Thanks!

Beth,
Nothing you can do in the patch, that I know of, will help ward off
powdery mildew. Brand new, first time pumpkin fields suffer from it. There is
something you can do about it next year. Go now and apply for training in
pesticide application at your county agent and receive a licence that all
farmers must get ( no big deal). Next year buy a gallon of Quadris ( here's
the hard part....330 bucks a gallon) if you havent already fainted you can
buy some Nova....a little cheaper but not much. A Gallon of Quadris treats up
to 12 acres so you probably have a lifetime supply. Scout your leaves
closely, when powdery mildew starts in your area, apply Quadris acc. to label
instructions, come back a week later with Nova and a week to 10 days later
with Quadris again. You will have no powdery mildew and probably no money
left. Some pumpkin varieties are starting to have powdery mildew resistance
bred into the seeds. Believe it or not, C. Maxima actually has some
resistance to powdery mildew ( compared to C. Pepo). I am a commercial
pumpkin farmer and will love the day when pumpkin varieties will all have
mildew resistance. There is nothing I would like better than to spray nothing.
