Please tell me this isn't blight!!

[Ovce domácí]

I don't think it's blight either, I've noticed that people often get understandably panicky about blight and assume all marks are the first signs when actually there are loads of other things toms etc can suffer from. Have know people dispose of entire plants before ensuring it actually is blight.

This is usually me panicking.

I think our have got some "scorch" off the sun. When it rains and then the sun comes out or when its been hot just after they were put out. Doesnt seem like blight. Might be the same here.

My tumbling tom in the greenhouse had some miner marks as well as yellowing leaves. I just cut them off. I have spuds in pots outside and they are showing no signs.

Quick update:

I am growing 3 kinds of tomatoes in my greenhouse:
Tumbling Tom
San Marzano
Jersey Devil

What i just realised is it's only the jersey devil that have the leaves dying off, it is getting worse by the day and now the flowers are doing the same! Still no sign of the stems turning brown though.

But what is odd is the other 2 varieties are totally ok and doing really well.

Anyone got any suggestions what this could be? I'm loosing my mind here

Tatty, its hard to say without seeing a lic of them.
Perhps you could post one and we can help you with advice.

I've not grown Jersey Devil, so I can't speak from experience, but I have had the odd occasion when tomato plants I tried to grow indoors looked unhappy and the flowers fell off. This definitely happened with Bajaja (which recovered when I put them outside) and possibly also Sweet Aperitif (which performed dismally everywhere).

I wonder if it might help to move them outside, if you can.

2 days on and blight would be making a noticeable difference.


Yup more piccies would be useful please!

[TattyJJ]

Well there is a noticeable difference for sure! I removed the worst of the leaves a couple of days ago, but it has spread rapidly regardless. To do the same again now would almost strip the plants bare!

What i don't understand is why it is only that one variety?

[Baldy]

It could (possibly) be early blight - though I've called wolf on that before and I don't think the pics are definite proof.
I would get rid of that plant though - and not in the compost bin.
Different varieties have different resistance - your others may be mildly resistant whilst current specimen is not.
Even if it is not blight I think that in an enclosed GH environment 'discretion is the better part of valour' - play it safe and get that plant out

Plant...? That would be 10 out of the 14 plants in there

The third and fourth pics look much more like botrytis than blight. I think I would cut off all brown bits every day (this will help with air circulation too) and cross everything.

[Penellype]

I agree that the picture of the flowers looks like botrytis. Its been so damp everything is suffering. Agree that removing the brown bits is the safest option and I would try moving one of the plants outside to see if it makes any difference.

In which case - fingers crossed - cut it back as Martin H recommends - not sure its mould from the pics but I guess blight in a GH is somewhat unusual.

[TattyJJ]

Ok, in the hope of doing some good i have further removed a load of leaves.
Also going to leave the door open at night, i was previously closing it up in the evening and opening it about 8am.
Also seeing as there is power i have small old fan in there on low to help move the air around. But if someone tells me this a terrible idea will take it out again.

Hoping for the best here!

Update:

Whatever it was that was killing my jersey devil leaves, it seems to have stopped THANKFULLY!
Almost all of the leaves were effected by whatever it was, but now it seems to have halted in not got any worse.
No doubt an already sluggish growth has been stunted, but some of the remaining flowers have started producing fruit. This make me happy
