I can't help, sorry, but I'm just curious: how do you know
that it's fusarium wilt?

I've always wondered about this - there are so many plant
diseases/problems - if my tomatoes suddenly wilted or died,
I'd not have any idea which problem they had.

The easiest way to identify Fusarium form the other wilts is to cut a cross
section from the infected stem, Fusarium will have a brown layer alway around
the stem just below the outer skin, As far as I know, once the soil is
infected, It will last a human lifetime, Some years its worse than others
however. Tried some of the "Gardens Alive" cures without results.
