One of my greenhouse tomatoes looks a bit odd. The leaves have started curling up, right to the top of the plant, and where the small fruits are just growing I wander if they will be alright. I can't see anything on these leaves but my eyes aren't very good. Any advice please, and is it likely to spread to the other plants which look very healthy?

Sounds like spider mites... at least here in the U.S. that would be my first suspicion. They're nearly invisible but their eggs are easier to see... look like tiny Christmas Tree ornaments on the underside of the affected leaves.

Treat mites with any good sulphur based miticide.

There are other possible causes, but since yours are greenhouse grown some of the the othe 'usual suspects' are eliminated... BTW... left untreated your plant is sure to die... and yes... the mites will spread to other plants...

(As an off question... you haven't used any herbicides any where near the plant have you?)

Thanks clanad., I've had a really good look and can't see anything, not even eggs but I've found some spray which I'll try.
