Potato leaf roll virus

Dan McAuliffe asked 11 years ago

I’m growing potatos for the first time and I fear one of my stalks may have leaf roll virus! What should I do and is this disease common here in Ireland?

Virus in potatoes is usually only a problem when the same home-saved seed is used year after year and vigour is lost, If certified seed is used there should be no problem.

It is spread by greenfly. Remove the affected plant, and check for blackleg disease which presents leaf rolling symptoms but there will be distinctive blackening of the stems below soil level.
