Powdery Mildew does NOT overwinter in the patch. 99% of all Powdery Mildew that plagues Northern growers come from airborne spores. Those spores need living plants to survive on. This is no problem since somewhere on planet Earth, there is always a succeptible host alive somewhere.

The best we can do is ramp up the start dates of our fungicide (or other) program next year to better match the weather & other phenolic indicators.

It also would help to identify & erradicate any other PM host plants (weeds) in the patch area.

Lets talk about powdery mildew......I have it worse than ever this year...plants are done, fruit are impatiently waiting to be cut free. Nothing that was successful in the past here has worked....daconil, nova, etc....I see powdery covering plants like peonies that Ive never seen affected before...can this all mean that this is a different "race", subspecies", variety, etc of powdery than what usually gets taken care of here??????

I experienced something similar to G this year myself. Maybe you're on to something.

Steve is correct. Clear the growing area of any other PM infected plants.

I neglected a clematis vine that clearly had PM. Now I have my earliest case of PM.

I have a feeling we'll talk more about Powdery Mildew this winter than any before. But what happened this year was not a super strain of PM. We just started too late. Just because we did what has always worked before doesn't mean it will again. Weather determines when we start & not all God's creatures subscribe to the same Degree Day modeling. So prediction can be very frustrating.

This year we saw a very early case of Angular Leaf Spot at Ray's patch just a few miles north of me. All he could have done to prevent it was to start fungicide spraying in the first week of June just as the vines began to run. Not ever having seen it here before, no one in this area ever starts fungis that early.

But you can bet your last 723 that next year Ray will start weekly sprays in the first week of June. And if he stays on his game (program), he'll never see PM either.

It wasn't what we used this year. It's when we started using it. Milk would have been good on June 1st just so long as it was applied religeously.

Mark these words.

Anyone who grows regular field pumpkins and Atlantic Giants(weather they are commercial or competitions seeds) will notice that the AGs seem to be more resistant to PM than the regular field pumpkins. PM was about ten days earlier in this area and caught a lot of people off guard including myself. My field pumpkins are not in good shape where as my AG plants the PM is in check......Tom

I've seen pumpkins grow even after frost killed off all the leaves. Roots will continue to pump out the juices even when the rest of the plant is done. As long as the vine doesn't turn to mush it can still serve as a conduit to the fruit. It isn't the kind of growth that can make or break a season, unless you consider that as long as it isn't dead, it isn't rotting.
