Selected endophytes of the genus Neotyphodium (formerly Acremonium) form stable synthetic combinations with tall fescue hosts (Festuca arundinacea). The combinations have improved resistance to invertebrate pests as compared to tall fescue cultivars not containing such endophytes. The particular combinations of the invention have reduced toxicity to livestock as compared to naturally occurring endophyte/tall fescue combinations. The seven preferred endophytes are AR501, AR502, AR510, AR542, AR572, AR577 and AR584.

Tall fescue endophytes

Selected endophytes of the genus Neotyphodium (formerly Acremonium) form stable synthetic combinations with ryegrass hosts (preferably Lolium perenne). The combinations have improved resistance to invertebrate pests and drought effects as compared to ryegrass cultivars not containing such endophytes. The particular combinations of the invention have reduced toxicity to livestock as compared to naturally occurring endophyte/ryegrass combinations. The six preferred endophytes are AR1, AR12, AR22, AR50, AR52 and AR56.
