Well, I've lost 2 tomato plants in the last week due to wilt. I thought I would lookup some info on the internet to find out what exactly I'm fighting.

This is what I've found -- there are basically 2 types of "wilt". Fusarium & Verticillium

Infection and disease development in Fusarium wilt are favored by warm soil temperatures (80° F) and low soil moisture, while Verticillium wilt develops best at relatively cool (55-75 F) soil temperatures.

I believe that what my tomatos died of is Fusarium wilt because it seems like as soon as the temp really started getting hot here on the Gulf Coast, the plants wilted almost overnight. There was no "reviving" them. Plus, it's been very dry here (lack of rain) so I've been having to water on a daily basis.

From what I've found out, there's not really anything you can do to prevent these types of wilt because it is present in the soil. So I guess I'll just have to go to planting my toms in comtainers in the future.
