Plant-parasitic nematodes on hemp in the Pacific Northwest of the United States
Pratylenchus spp. were the most frequent plant-parasitic nematodes found in hemp fields in Oregon and Washington. This study reports for the first time five Pratylenchus species (Pratylenchus crenatus, P. fallax, P. hexincisus, P. neglectus, and P. scribneri) associated with hemp in Oregon and Washington; P. penetrans was also found in the region on hemp. The host status results indicate that hemp can be considered a non-host for M. chitwoodi and a poor host for M. hapla and P. neglectus.
