Are you growing them in the same spot every year or rotating with other crops?
One cause of scab is said to be dry conditions during the first few weeks of green growth. However it sounds like scab is now endemic in your soil and you may have to avoid growing spuds for several years.
thanks a lot for the reply,its what I thought iwould have to do ie not to grow except in sacks.
The only thing is that scab normally affects the outside of the potato and is a sign of too much lime in the soil. The holes are keel slugs and they are definitely impossible to control.
The other thing about too limy a soil is that it tends to lock up some of the trace elements and lack of them can cause brown veining inside the potato.
Scab is a bacterial problem and seems to get worse when it is dry
I went on the Potato Marketing Board Varieties web site. It tells you all about each potato type in fair detail - including which virus and assorted nasties they are prone to. I wish I hadn't ! ! ! Very informative but a total Horror Story. Form now on I will choose, plant, close my eyes and pray!
hi reg had the same problem this year seconds and main crop badly affected
muck dung in over winter which i feel did not help as ground was very wet on digging
up spuds 1st early not affected so will growing these only bit worried a bout ground

cause most likely weather related
Not sure of your plans for next year broad bean but don't forget about crop rotation.
