Sick tomatoes

Both my mum and i have sick tomatoes. Mine are in a greenhouse, hers are not. about 6 weeks ago I gave her 2 of my plants as one of hers was failing and then a month ago she gave me one that I had grown from seed back in return.

I showed pics at a local garden centre yesterday and they shut it is possilly down to me overcrowding my greenhouse so was lack of ventilation/too humid etc I have now removed most of the sick bits off mine but don't know whether it's going to help or or this is even cause.

Grew last year in a plastic greenhouse with no issue, I'm a bit new to this.

Thoughts?

 

Welcome to Gardeners Corner

Looks like blight to me i'm afraid

They won't last very long once it's taken hold, I've got the same here. Had a couple of fruits but most of them have turned to mush.

Don't compost any of the diseased plants, and make sure you clear all them out of the greenhouse.

 

I'm not so sure. Looks like stem rot?

 

Just looked that one up Freddy, reduce humidity, remove decaying leaves and fruit, Spray with carbendazim.

Having looked at the plants again, I have 2 that appear to be unaffecte. One was moved putside about a fortnight ago as leaves were curling. The other is still in greenhouse but was on its own, leaves and stems all look ok atm

 

Curling leaves could be a sign of a wide variation between day and night temperatures especially if they are curling inwards - this does not indicate disease. The picture, however, looks like stem rot.

 

If it was mine I'd call it blight, its not good either way, and unlikely to recover.

 

Definitely blight .Ideally the plants need to be burnt.

 

Thank you

 

If it were stem rot is carbendazim still available?

 

I believe not. Out of interest, what are the fruits like?

 

Mixed. Some are brown at the top, some are absolutely fine (at the minute) and are still growing. I've moved everything away from greenhouse and am watering from door. I know it's probably pointless but I've worked to hard I don't want to give up. The peppers and chillies I have in there are fine.

 

Ali, peppers and chilies will not be affected by tomato blight anyway. Why have you moved everything away from the greenhouse and why are you watering from the door?

 

I'm a bit surprised that blight is infecting tomatoes under cover. I've had it on my outdoor crops but never in the GH or polytunnel. It's hard to tell from the photo but I, like Freddy, wouldn't rule out stem rot.

 

Hiya Dave

Blight under cover is quite unusual, but not totally unheard of. I seem to recall having it in a greenhouse a few years ago. At the time I put it down to the fact that I had all the vents open, along with the door.

@Ali_Bird2001 says that some of the fruits are brown, I think it's blight.
