Abstract  The influence of the ryegrass endophyte on plant-parasitic nematodes in a cool moist environment in New Zealand was evaluated in a pot and a grazing experiment. Nematodes of the genus Paratylenchus made up 99% of the fraction of plant-parasitic nematodes and their numbers were higher (P > 0.05) on endophyte-free plants in the pot experiment and in fields containing monocultures of endophyte-free ryegrass. Nui endophyte-free plants and pastures had higher dry matter yields than endophyte-infected plants and pastures. The effect of endophyte strains on nematodes was inconclusive.
