Lets just all hope we won't have to worry about any blight this season. I'm prepared though just in case, I ordered this Copper Fungicide Dust that looks promising.
Thanks for the heads up, Steve! That was a really good article. Be sure to check out the link on there, Tomato Defense Guide. Good pics of it there, as well as a few other tomato diseases for comparison.
They said I ought to rip out my volunteers (I have a couple in the compost pile I am watching, just to see how they'll do.) But another site said to destroy this years volunteer tomatoes only if your crop was affected by late blight in the year prior, so I'll just keep an eye on them.
