Kentucky 31 is currently primarily used for lawn and turf grass. It does have a more coarse appearance than improved types. While Kentucky 31 tall fescue has and is used extensively for livestock pasture grass, agronomists no longer recommend Kentucky 31 for livestock pastures due to the presence of endophytes. Endophytes are a naturally occurring fungus in fescue grass species that protect the grass from insects and disease. Endophytes cause issues with cattle and horses that graze on fescue grass that contains them. See our beneficial endophyte species for forage tall fescue.
