Tomato plant fallen over

[sunnymay10]

Hi everyone,


hope I can post a picture as you need to see, so this is what happend.
Tomato plants of different types were all growing well, when I went in yesterday, one of the biggest one was flat on the ground, I thought our cats must have knocked it down, but when I went to straighten it, it snapped from nearly soil level.
If you look at the picture it looks old and woody as if whats happened has been going on for awhile, but a bit further up the stem are some knobbly lumps.
Any ideas please, I'm worried it might be something that will spread through the other tomato plants in there, it's also next to a few rows of potatoes, hope I can put a picture up or you want know what I'm on about, here's hoping.

If it was me I'd cut the brown bit off and stick it in water. The knobbly bits are where roots will grow. I'd guess the brown bit is just where it's started to die off after being snapped.

could be fusarium wilt, or some other wilt.

The knobbles are normal, they are where the roots form

I'd think the brownish bit is just where it's began to die off after being clicked. If it was me I'd cut the brownish bit off and put it in the water. The knobbly pieces are where origins will develop.
