The feathertop problem in Mitchell grass pastures

Abstract

Seeds of Aristida latifolia (feathertop grass) in Mitchell grass (Astrebla spp.) pastures are the main cause of vegetable fault in wool from sheep grazing these areas. High stocking rates, particularly when the plants were young, reduced the build up of A. latifolia to only 4 000 plants compared with 35 000 in an adjacent field at low stocking rate. Control of A. latifolia by management strategies, (heavy grazing followed by pasture recovery in the wet season) is recommended.
