tomato plants that have a black colour on the stems
By Bensed
United Kingdom 
I have two tomato plants that have almost overnight developed a black colour on the stems, the leaves have turned yellow and have dried out in some cases. I think it might be blight.
Two questions -
Can I still eat the fruit?
Should I burn the plants now to avoid it spreading?
Update -
Sorry they are in one container and are in the open air.

Hi,
Thanks for the reply, I'm in Cambridgeshire and we have not had any frost yet. So it is OK to use the toms? that is the main worry as I have a young family and don't want any issues.
I shall pick all the toms tomorrow and get the plant burnt ASAP.

Probably blight, but may not be. Did the plant get frosted? Frost can blacken stems, too. I don't know where you are in the country. The toms look ok. Collect them (even the green ones) to save them, and get rid of the plant (preferably by burning). Phil J
