Sheeshshe, I had early blight on my tomatoes, pretty much unheard of in Wyoming. (I had to look it up; I hadn't a clue what was going on.) However, we had a wet, cold June, and I probably over-watered in July.
I pruned them all, especially removing the foliage up to a height of about a foot, and they are seriously on the mend now. Mine needed better air circulation. It might work for yours. If you have a few you could experiment with, you might give it a try. I saw decided improvement within 48 hours.
