tomato blight in polytunnel

[tlck9]

What can I do if anything, I have some brown leaves on the tomotoes, does this mean they are ruined.

I have removed all the leaves that are showing blight, but is this the end?

Are you sure it's blight? I would think it more likely to be botrytis in a polytunnel. If the later, hacking off and carefully removing leaves should keep things under control until well into the autumn. Try to stop flower end sitting on leaves, they're a magnet for mould.

Just brown leaves doesn't mean blight. Leaves brown up a bit when they get mature. You can just remove them.
