The control of weedy grasses in cultivated oats has traditionally been left to cultural methods. Most herbicides developed for wheat and barley show little selectivity between oats and the principal grassy weeds of southern Australia, namely annual ryegrass (Lolium rigidum) and wild oats (Avena fatua, A.sterilis and A.barbata). Currently chlorsulfuron (Glean(R)) is the only herbicide registered for control of annual ryegrass in oats in Australia. While chlorsulfuron represented a major breakthrough in oat husbandry its use is inappropriate where oat/legume mixtures are sown and on soils where pH is greater than 8.5. No product is registered for control of wild oats.
