Hello all!

Noticed today that a lot of my potato leaves are starting to curl up and shrivel. They've all be sprayed for blight and green fly but it doesn't seem to have stopped it. They've been watered regularly so very much unsure what it is attacking them. Can anyone help? I've left some photos so you can see exactly what it is.

Many thanks and happy growing!

You’ve ruled out most things, could be a virus. 

Are you sure there are no insect ?

Thanks for replying!

I've read it could be a virus called 'potato curl' which basically means taking out the infected plants to save the healthy ones. Apparently bugs will eat the sick plants and carry the virus over to the healthy ones. Maybe a possibility it's that?

Thanks

Yes, it could be. 

Have a look at the stems to see if there are any dark patches on them caused by black leg.

I find the bug sprays can damage the leaves
