Fusarium Wilt

Fusarium Wilt

I have two tomato plants (Sweet 100) that were both infected with fusarium wilt. And they were growing pretty well too! :( Is there any point in keeping them? Everything I've read so far says to burn to plant and/or throw it away. I have two other Beefsteak plants that I've grown from seed that are doing pretty well and I don't want to infect them either. Thanks for your help!
