Tomato Plant Discoloration Problem

[craftymarie]

One of my tomato plants in the PT has got some very dark brown discoloration down the main stem which clearly isn't right.

The tomatoes growing on it look to be OK and no obvious blemishes.

Should I cut the trusses off with tomatoes and hang them up in the polytunnel and dispose of the plant? I'm concerned that whatever it is will spread and infect the remaining plants.

It could be blight,(though you usually get blight in wet, warm conditions) though toms will start to go over now anyway so I would pick all the toms off that plant and dispose of all the greenery. Ripen the toms indoors on a warm windowsill.

Could be blight, could be botrytis - in either case I'd definitely pick the toms and dispose of it.

Thank you, there aren't that many tomatoes left so I will pick them all off and get rid of the plant as you say. Better safe than sorry.

Looks like botrytis to me. I had this on two plants. It didnt spread so you should be safe.

Just in case is better put a picture here so you could identify the problem in the future.

Sometimes, if you have lots of green toms on the plant, it's worth wrapping the infected stem with sellotape, this supports it and also stops any spores being released to spread it to nearby plants.

Usually gives enough time for the green toms to ripen, so well worth a try.
