Just when growers on Canada's Prince Edward Island thought they had things back together, a finding of bacterial ring rot turned up on an Island farm.
Officials are trying to find out where it came from. Fortunately the farm is not a seed operation.
It has not yet been decided how the infected potatoes will be destroyed but CFIA is taking steps to ensure the ring rot does not spread.
Usually there are no external symptoms on infected tubers by ring rot (Corynebacterium sepedonicum) though in other cases there may be areas where the skin is a pale brown or buff. The skin is easily rubbed off where the vascular tissue reached the surface at the stolen attachments.
