Tomato disease?

[Robert_Brenchley]

One of my toms was wilting terminally so I dug it out to see what was going on. ##The roots had died and the base of the stem was rotting. Any idea what this could have been?

short of a drainage issue - i assume they get the same diseases at potatoes? blackleg, for instance?

I'm inclined to think phytophthora, but that's associated with waterlogging. My soil dries out well, and the other 47 plants all look perfectly heathy.
