The responses of wild oats, Avena fatua L., annual rye grass, Lolium rigidum Gaud., paradoxa grass, Phalaris paradoxa L., great brome, Bromus diandrus Roth., silver grass, Vulpia myuros (L.) Gmel., and barley grass, Hordeum leporinum Link. to fluazifop-P, haloxyfop, quizalofop-ethyl, fenoxaprop-ethyl, sethoxydim, and clethodim were compared in a glasshouse pot experiment. Fluazifop-P, haloxyfop, quizalofop-ethyl and clethodim were active on all species except silver grass, while fenoxaprop-ethyl and sethoxydim were active only on wild oats, and paradoxa grass. The same herbicides were evaluated in field experiments with silver grass, barley grass, and great brome. These experiments confirmed the tolerance of silver grass to all herbicides. Barley grass and great brome were effectively controlled by fluazifop-P, haloxyofop, quizalofop-ethyl, and clethodim. Sethoxydim at 186 g per ha gave reasonable control of barley grass but was ineffective on great brome.
