Tomato disease? Antoher thread ...

[redser]

Hi, sorry but I did look around and can't seem to find a diagnosis that matches my problem. A few photos below. I thought it was blight but then maybe not. There are no tell-tale brown spots with yellow rings? Does anybody recognise the problem, it does look very sickly.
It's a good height (about 30 inches) and has plenty of flowers and some fruit set. I put it up in the tunnel about a month ago so it's had some tough nights. It had some small wind/sun scorch before it went in the tunnel but it just looks awful now. You can see the difference compared to the one beside it which just got planted out. The underside of the leaves look ok to me. But the leaves are badly discoloured and are some actually crispy and break if you try to bend them.
Appreciate any feedback as I will pull it if it is a desease. I don't want it to spread. But then maybe it's just been beat up from weather conditions??
Thanks a lot

I don't know much about diseases but would be tempted to take those bottom leaves off anyway. I would be more concerned how the fruit turns out. Sorry I can't be of much help.

Ooh dear, that looks rough. I'd take off the bottom leaves and try seaweed feed. Does it need a bigger pot with fresh compost?

[redser]

Thanks for the replies. It's actually in the ground and has been for a month. I'll remove those bottom leaves. The fruit seems to be setting fine but I'm concerned it has something that could spread to my other plants.
Cheers

If they have been in for a month, could it be the cold spell we have had. A guy on our plot lost loads of Tom plants from his polytunnel.

Oops, sorry Redser, wondered why I couldn't see the pot!

Tomato leaf mold apparently, according to the guru...remove bottom leaves and venitlate.
A purplish brown patch on underside of leaves, top is more yellow...

Those white rings are probably a fungus of some type but I don't think they are the cause of the browning, just something taking advantage of the problem.

[redser]

Thanks again.
Actually I know what those white spots are, they are just residue from a seaweed foliar feed I gave it. Just dried out that way.
Did some more looking for Tomato leaf mould and it seems to fit alright. That month in the tunnel was fairly damp at times due to closing it up in the cold. I think the best thing to do is pull it and burn it. Cheers.
And then there were eleven. I'll show them who's boss ...

no!!!! dont rip it up!!!! just take off the lower leaves....

[redser]

Haven't done it yet. Was reading that it can spread. Would I not be better off dumping it rather than risking the other plants in the tunnel? Or does it not spread?

[taff]

hmmm, ok, maybe I overreacted, but as far as I can tell, it spreads if every plant is in the same condition, so hopefully, once you've improved the ventilation, the fungus can't get a hold becasue the conditions aren't right for it anymore.
So, yes, you're right, rip it out, but if you can find room for it away from every other tomato plant, I'd take off the lower leaves and see if it gets better.

[redser]

Cheers. Will take it out and see if I can trade something for a replacement spare around the plots.
