Powdery mildew all over a/c zucchini vertical and under tulle -- so I removed whole plant

My vertical method is quite terrible -- the leaves get all squished up in there, no air flow at all.  Then factor in the tulle too.  Hadn't noticed until today all the PM in this plant, but then, have been pretty preoccupied the last week with a dog with a broken leg and then another dog who turned up three-legged lame three days later.

Didn't feel like trimming the plant -- it has produced one single zucchini all year and might have produced another at some point but nah, decided to just toss the whole thing.
