I’m sure you’re getting it in spades this season with all of the WET.

When I have it (usually on Zucchini plants in a wet season) I use Copper Spray and that works like a charm. Zinnia seem to get it too, and a blast of copper usually helps them, though they make so many mildew-resistant varieties now that it’s not usually a problem.

I wouldn’t beat yourself up about the straw; it’s more of a moisture thing with MORE than perfect conditions for All The Mildews this season. :(

Snapped some pics. The odd thing is that from what I've read, downey mildew tends to be pretty plant specific although I did read that you can easily have more than one type at the same time -- favorable conditions and all that.

Italian Oregano (I still munch on a leaf every time I go out there)

Tatsoi (might munch on a nice green leaf)

Celery (Tried it - tastes like celery)

Squash

Cucumber

Bean

Watermelon

Seems like a lot of plant types -- mildew types or maybe it's something else. Tomato and pepper completely unaffected. Brassica, an herb, cucurbits, bean, celery.

Tatsoi is well past it's prime growing season so I may as well pull it. Not eating leaves that I spray with something. I can pull it, pick out all the good looking leaves to eat and burn the rest. Celery stalks not affected and they're growing good otherwise. I do have one crowding the Shishito plant so I'll pull it out and eat baby celery. If everything else survives and makes fruits/beans, that works.

Of course part of me wants to pull it all to help prevent it from loading up the soil with spores.
