A technique was developed to determine if Pratylenchus minyus influences Verticillium wilt of peppermint solely by providing readily accessible infection courts to fungus hyphae. Detached peppermint stems were rooted at two locations to provide plants with two root systems. The root systems of these plants were placed in soil in separate plastic pots and inoculated with various combinations of Verticillium dahliae and/or P. minyus. The nematodes influenced the length of the incubation period and the incidence and severity of wilt even when each pathogen parasitized separated root systems of the same plant.
