    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Many cool-season forage grasses associate with an endophytic fungus of the genus Epichloë. In Sweden one of the most important forage grasses is meadow fescue (Festuca pratensis Huds.), which is known to associate with Epichloë uncinata, previously named Neotyphodium uncinatum. READ MORE
