I'm not convinced it is blight. I'd wait and see. If it is blight it's too late anyway. Are you growing in a greenhouse? It's less likely if so. I've not had blight on toms in a greenhouse, yet they got it when grown outside. I have seen blight in a greenhouse when it was a rainy summer and blight was everywhere and the greenhouse door was left open 24/7.

They just look a bit mature to me. Once you have lots of fruit set it's worth removing some of the leaves anyway, to increase air flow. If any are offending you whip 'em off. Blight is slimy and black and horrible.

[Florence Fennel]

I've never seen blight, but my tomatoes have looked like yours. Do as Flum says and remove some of the foliage.

[deltz]

Thanks for that guys, never seen marks like that on the actual stem? And the spots themselves are quite high up on the plant, will remove foliage!

Here some more pics!

Sorry to ruin the party but looking at your second set of pics it could well be blight, if it is there is nothing to be done the plants will die very quickly.

You have nothing to lose by waiting if they still going in a week or so it ain't blight.

Thats what I thought Is there anything I can apply, heard of a copper solution once, would that still be effective at this stage? Should I take out the plants affected, would it still spead to rest? Thanks!

[Davyburns]

I was told that copper sulphate solution or bordeaux mix should be applied before they get hit, but if I'm wrong, I'm sure someone with more knowledge will be along shortly to correct me

[Potstubsdustbins]

DB is right copper sulphate is a preventative.

Deltz try a google for tomato speck or tomato spot, 1/8" to 1/4" blackish lesions more preverlent in cool moist conditions. Plenty of pics for you to have a look at.

Early blight is only a possibility at this stage.

I've had blight in previous years and it hasn't looked like that .......it's not little spots its great big patches , starts on the ends of the leaves and works its way along the stem .

Doesn't look like blight to me either - blight usually appears in larger blotches that are equally visible on the underside of the leaf. If you look closely at a ablight infected leaf, there is usually a faint greyish outline to the infected area.

[taff]

nor me, you get sooty patches on the stems in big blobs rather than tiny brown rusty bits.

[Nicos]

If I had to make a choice, then I'd go for the 'it's not blight' choice too.

I think you'll know for sure either way by weekend though

I'd take off the worst affected leaves and burn them/put in household rubbish bin- that'll help with air flow too.

Let us know how you go on.

It looks like the sort of damage you get outside in dodgy weather.

I'd say it was a fungal problem, but not kills all your toms immediately blight. Not perfect, it'll weaken your plants and you might lose a few toms, but I wouldn't cut them down and burn them now.
