Tomato blight?

My gardeners delight tomatoes have been doing well, but have started going brown and rotting away. I thought it was just the ones that had been sat on the ground in water, but it's spreading up the plants. Have I got tomato blight? Do I cut off all of the infected trusses, or am I wasting my time? There's still plenty of decent ones there, but I'm chucking more and more away each day.

 

Deserter, if you have brown markings on the stems as well as the leaves than you have blight, and you should pull them all and burn them. If you cannot burn them then my advice would be to spray with a fungicide to kill off the spores, then get them out, put them in a black bag, tie it tightly and put them out with the household rubbish. Do not put them in the compost bin or put them out for recycling. You should also sterilise the soil they were in with Armillatox but do not replant there for at least a month. David.

 

Sounds like blight, mine are showing signs now as well.
Its not suprising bearing in mind the awful summer we have had, but mine tend to get it most years late in the season, usually about the end of september.
I usually take off the toms that are near ripening, and watch what happens for a bit, if they are only slightly affected you could try a copper spray, but be quick.

 

Had the same, had to trash the lot of mine this year. Brown stems and fruit.

 

Has happened to both my dad's and the other half's. Mine looking good so far...

 

Same here - believe it or not. Had a real wet summer and I don't see a tom plant growing anywhere. We are just about to buy them on the black market

 

Thanks all, tht sounds fairly conclusive then! There's still plenty not affected yet but I'll start retrieving the ones that are on their way to ripening. They're growing in grow bags well away from anything else, so at least I don't have to worry about it spreading to other plants.

Talking of which, I was going to empty the grow bags at the end of the season onto a patch which we'd use for potatoes next year - is this a bad idea? The other alternatives are to take it to the municipal garden waste skip or stick it out with the household rubbish.

 

Can the spores from blight live on in a grenhouse until next year & if so is there any treatment to get rid? I wash my greenhouse thoroughly with jeyes fluid every spring, but the blight returns. By the way I bought 3 tomazing plants this year, kept 2 & gave my mother one, it hasnt got blight & mine have!

 

Acerhead,spores can overwinter in the ground, you are doing right by washing the greenhouse with Jeyes, but I would be inclined to increase the strength slightly and do it now. If you grow in the ground in the greenhouse then give this a good drenching. Also, all pots and containers used in the greenhouse. By doing it now the greenhouse will be free of the Jeyes fumes by the New Year. David.
