Loline alkaloids for better protection of pastures from insect pests

Abstract

Loline alkaloids are non-toxic to livestock and protect endophyte-infected fescue against insects. They are not present in perennial ryegrass (PRG) infected with its natural endophyte. PRG has been artificially infected with the loline-producing endophyte AR525, sourced from tall fescue. Keywords: endophyte, ryegrass, lolines, host-symbiont interaction
