Fusarium a death sentence?
As in prior years, my tomatoes start growing very well, then the yellowing starts on the lower leaves and works its way up and it's a race to the top. This year it started even earlier than usual, and a nursery person whose judgment I trust is pretty sure it's fusarium wilt. He said that once it's started there's nothing you can do other than suffer it or pull the plants. He also said that it's very prevalent in coastal SoCal, and short of solarizing the soil or using containers, there's no way to prevent it.
Is he right? Is there any product that will help? I ran some searches here and found several discussions of fusarium, but none seemed to mention a treatment.
Thanks for any help. Don
