Popis:	The contamination of a perennial ryegrass (Lolium perenne) dairy pasture infected with a novel endophyte with other ryegrass/endophyte associations was studied over 2 years in Hamilton, New Zealand. Five management treatments (turnip crop, usual rotational grazing, usual rotational grazing followed by topping, silage making, hay making) were applied to produce a range of natural reseeding levels, and then three establishment methods (spray/cultivation, double‐spray/fallow, hard‐grazing) were used before drilling AR1 endophyte‐infected perennial ryegrass (no lolitrem B or ergovaline production). Contamination from wild endophyte (Neotyphodium lolii)‐infected perennial ryegrass, endophyte‐free perennial ryegrass, wild endophyte‐infected hybrid (L. boucheanum syn. L. hybridum)/Italian ryegrass (L. multiflorum), N. occultans endophyte‐infected hybrid/Italian ryegrass and endophyte‐free hybrid/Italian ryegrass tillers was determined. Contamination was assessed in the two summers following the autumn (...
