Epichloë endophytes: New perspectives on a key ingredient for resilient perennial grass pastures

The confirmation that Epichloë endophytes are important for pest resistance in New Zealand pastures led to the development of a range of novel endophyte strain × host plant combinations that enhance the persistence of the grass, while mitigating adverse effects on grazing animals. Successfully delivering these endophytes to the pastoral industry has required the development of a range of scientific and commercial capabilities. In March 2012, the New Zealand proprietary seed industry established the Endophyte Technical Committee. This is a cooperative forum to ensure that endophyte strains in commerce or under development are tested uniformly, and to publish industry-agreed descriptions of the animal safety and insect control of commercial endophyte strains each year.
