Abstract

Annual grasses were removed by l,l′-dimethyl-4,4′-bipyridinium salt (paraquat) from subclover (Trifolium subterraneum L.)-Hardinggrass (Phalaris tuberosa L., var. stenoptera (Hack.) Hitchc.) pastures with only temporary damage to these species. If sprayed at the recommended time, total forage production was unchanged and forage quality was improved. Species composition of the pasture was improved by all spraying treatments.
