Summary Root-knot nematodes are parasitic roundworms that infect a large number of plants, causing stunting and poor growth. One way to manage these parasites in nursery or landscape soils is by selective planting or rotation to nonhost or resistant species. We evaluated the host status of a large number of common herbaceous perennial ornamentals to establish a base of knowledge for nonchemical management of root-knot nematodes.
