  • Ryegrass endophytes
    Patent number: 6072107
    Abstract: 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.
