I believe I have fusarium wilt on one of my container tomato plants. Looking online at photos, my tomato plant exhibits the same symptoms - yellowing and wilting on random stems while other stems look vigorous and healthy. I was wondering what the likelihood this could pass to my other tomato plants which are in individual containers grouped closely together. I know that it can be transmitted by some insects, but I think it's unlikely in my case unless the bees can. Still would like a confirm.

As for the plants, they were given to me and I believe were grown from seed. Another reason why I'm asking is, I plan to reuse the soil from other (wilt-free) containers for next year. I like to use the soil twice before I have to dispose it. Fyi, I'm a city dweller.
