Root-lesion nematodes 

Pratylenchus spp.

Infect many plant species including potato. For example P. penetrans has more than 350 hosts ( Wikipedia). No potato resistance data known. The nematodes play a role in the Potato Early Dying Disease (PED) by increasing the damage caused by specific Verticillium dahliae isolates ( MacGuidwin & Rouse, 1990;  Botseas & Rowe, 1994).
