Root-tip galling.

Has been implicated along with L. attenuatus and L. elongatus in carrying Docking Disorder of sugarbeet in England.
The nematode is probably a vector of plant viruses; viruses have been detected in the body but definitive tests of transmission have not been performed (Clavero-Camacho et al., 2
