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.
