I am almost certain this is what kills my tomatoes each year. I have noticed that certain varieties DO seem to live longer and one of them is Big Boy. I also noticed Red Zebra gave it a good go this last year. Last year was my last for trying to plant in ground. Another one that lasted was Amulet (from Andrey). I would love to participate in such a trial. My first year growing here was the best then year after year it got worse and now you can't plant at all in the soil.
