Help please.

My potatoes crop is good but it has been infected with small black slugs
under the ground that bore into the potatoes. Although we do cut these
areas away I would like to stop this happening again next year. Does
anybody know a cure for this problem.

Also, should I now lift the rest of my potatoes crop and store them in a
dark place for use or leave them in the ground and lift them as I need them?


Thanks.

Paul Bonner.
