Lesion nematodes (Pratylenchus spp.) is a nematode pest. It was first detected in Alaska in 2004.
Root-lesion nematodes (Pratylenchus species) are endoparasites that cause severe losses to hundreds of different crop and ornamental plants by penetrating roots and making their way through the tissues, breaking down the cells as they feed. They deposit eggs from which new colonies develop.
