WLLady. It is unfortunate that blight and Septoria blow in on the wind. I too have that problem most years. To increase air flow around my plants, I mulch with black plastic and I try to remove the lower leaves early to prevent splashback, even though it breaks my heart to rip off healthy green leaves. If I don't, the "nasties" take hold and I end up having to remove them later anyway. Leaving lots of space between plants and pruning to one or two main stems also helps, although I'm not good at either of those things.
As to disease-resistant plants, they are mostly hybrids, and some aren't even that good by all accounts. I have heard that Iron Lady was a failure, but that Mountain Magic and Plum Regal are better (at least in the southern states).
If you are into currant tomatoes, Matt's Wild Cherry is open pollinated and said to be resistant. I haven't tried it yet, but I did grow Sarah's Galapagos, another wild currant. I was amazed to see it get hit by Septoria and to completely grow out of it! Too bad that currants are such a pain to pick, but they do produce LOTS of fruit.
