Is this tomato blight, if not any ideas what it is please?

It is a difficult decision tbh, and as ameno says it progresses quickly.

When I've had blight I've noticed lots of soft dark brown splodges all over the leaves, so it's not looked the same as in your photos.

Have a look st this thread it's about tomato and potato blight and some of the photos are lost...but the discussions are interesting - there's loads of info on it and maybe the next few days will help you decide.

Gut feeling....not blight but whatever it is needs your close attention.

I don't believe any of your last pictures are blight. Agree with others that the pics before those with the brown stems are blight.
It's the one disease that we all dread and can do nothing about. It's worse in years which are warm and wet....typical British summers really.

I thought I would add a picture to this thread that people might find useful.

A few days ago I noticed the tell-tale signs of blight on my Balconi red tomato plant. I immediately picked all the green tomatoes and removed the plant. I spread the tomatoes out in a tray and I am checking them every day for signs of blight. This is what I am looking for:



All of these have blight and are not edible.

Going back to the original photos. I had a lot like this this year and I decided (eventually) that it was some form of wilt or bacterial canker. The leaves started like that (brown on the edges) then suddenly collapsed. The stems then dried up and got mould.

Because it was relatively late in the season (late August) when all this happened, I left the fruit on the plants and they ripened BUT some of them have little "haloed spots" on them - which apparently is a sign of canker.

They still tasted good but its a complete clean down of the greenhouses for me this year and no re-using compost next year (I grow in buckets). I've also seen that I should soak (briefly) any saved seed in bleach to make sure the canker doesn't come back from the seed.
