Cyst nematodes ( Globodera and Heterodera spp.)

Cyst nematodes are sedentary endoparasites. They typically have smaller host ranges than the common root-knot nematodes. Several species are among the most serious parasites of their favored host plants, including G. pallidum and G. rostochiensis (potato), H. glycines (soybean) and H. schachtii (sugar beet). Cannabis sativa is not a favored host for any known cyst nematode species, and Globodera spp. have never been reported from the plant.
