What do you make of the below on powdery mildew ? Seems a reputable source.

in the paragraph above the image of a mildewed tomato plant.
It certainly would be a reputable source of information.
Spores are tricky things and I don`t trust them not to overwinter in the protection of a greenhouse even in a northern garden. I think this article mainly is referring to outdoor conditions.
Cleaning and sanitizing a greenhouse, whether you are a pro like Mark who for sure knows how critical sanitation is in his professional greenhouses or a small greenhouse hobby gardener like myself it is a very important job.
I had a soil floor in my greenhouse but I did use a shop vac in the fall on and under the shelves, walls and in the corners to deal with cobwebs (and the dried up critters caught in them) .
