Abstract

New Zealand perennial ryegrass (Lolium perenne) pastures generally have a high incidence of endophyte (Neotyphodium lolii) infected tillers (Hume 1993), and increases in incidence are not uncommon. Prestidge et al. (1984) recorded an increase from 8% infection six months after sowing to 40% 18 months after sowing. Newly sown pastures sown with high endophyte seedlines at Palmerston North provided an opportunity to assess whether similar changes would also occur in this situation. This paper reports results over the first 13 months following sowing.
