Slugs & Spuds!

I've been growing potatoes for 30+ years & can honestly say that this has been the worst year for slug damage. In previous years we've had some damage but were able to store at least 75% over winter but this year I reckon every spud has slug damage - no exaggeration! I realise it was an extremely wet & mild winter so that didn't help & because of this we soaked the area where the spuds were growing with nematodes - no effect!
I realise that no potatoe is completely slug resistant but I'd appreciate any suggested varieties that other gardeners have found to be resistant' I've a list of resistant varieties & the variety & grew - Sante - was on it!

 

Both earlies, Rocket, & maincrop, Sante, are affected.

 

Only grew Mayan Glod this year, very little damage on them.

 

Am I right in thinking there are various types of slug and the ones that eat spuds underground are a certain type?
Quite a lot of the really big ones you see around tend to just eat decaying matter.

I did hear you should add a few slug pellets when you earth up.

 

Arr, the black keeled slug will ave it away with your spuds in Davey Jones locker

Old Pirates tale says that only an application of nematodes will belay the little varmits.
