You have what we refer to in South Georgia as tomato wilt virus. This is real bad with peanuts in our area, but also affects tobacco and tomatoes. Sorry to say there is no treatment for this disease. It is said to be carried by a very small insect, called afids or thrits. I had two beautitful tomato bushes putting on tomatoes like crazy, then in a couple of weeks the leaves started twisting. Tomatos on bush will probably mature, no more growth. Some people say this can be helped by washing your hands in milk after planting one plant and before planting another, am not sure about that. I ahd it last year, and made sure to use new soil, cleaned containters, etc and got it this year as well. I planted disease resistant type 444.
