Thank you for your continued suggestions Rick and Rita. I have tried so many so called "disease resistant" tomatoes and all had the same problems. I think now that my last hope will be changing to town water, and if that doesn't work, I will have to assume that the problem is a soil or wind blown virus, and give up. I was wondering though, are beans susceptible to tomato viruses? I know that nematodes can invade them both, but I have checked for that, and there have been no lumps on the roots at all. You are right about our soil, it is very, very, well drained, and needs heaps of water, which it gets.
I will ask around. You may not realize that I live in Australia, so your co-op finder site wouldn't apply. My neighbors are not gardeners, nor is anybody that I know living locally.
