I pulled up a few potato plants today and a couple of the potatoes had what appeared to be blisters on them. They were the same oclour as the rest of the potato and the texture seemed normal, it's more of a shape deformity. I've looked in a few books and the only vaguely similar ting was wart virus, which from pictures looks far more severe, and my potatoes are Alan Roman's orgainic seed potatoes so it seems unlikely. Does anyone have any other ideas?
I was looking for reasons for choclate spots on my potato leafs and found this. It might be helpful to you

I have decided taht my spots are early blight as apposed to late blight. I did not know there was more than one kind of blight!
Might be scab, which isn't a problem except for the looks.

What a fab site :)
I think it's scab ...at least I hope so.It would be pretty bad luck if my potatoes caused the quarantine of the North West!
this is helpful - when I bought my seed potatoes from Wilkinsons some of them had funny circular marks on - from the website it looks to be silver scurf ... I swapped them for a different batch.
