PRATBR
Pratylenchus brachyurus is a root-lesion nematode that reproduces mainly by mitotic parthenogenesis. It spends its entire life cycle inside plant roots or in surrounding soil, feeding and moving within root tissues. Eggs overwinter in roots or soil, hatching in spring to resume infection. Seed is not known to be a pathway.
