Diseased tomato plants

Hello

I have been growing in my first polly tunnel.

Until recently my tomatos have been doing very well, but this morning I noticed many of the leaves had turned partly grey and were brittle to the touch, also on parts of the stem there were brown areas.

It has been cool and wet, there is quite a bit of condensation in the mornings which disipates during the day.

What have i got?

What treatment?

Thank you

Richard

 

Hi Richard

Welcome to GC

1st thing you should do is ventilate the greenhose 24 hours a day get the air moving through this stop a lot of the leaf problems you are having and only water the soil not the leaves.
I think Blight ( fungus ) by what you have descibed , I dont know if anything is availabe to spray others may sugest somthing, you can cut the realy badly infected leaves off , to stop it spreading.

A good autumn clean out as this can overwinter in the soil.
