The herbicide tebuthiuron was applied at rates varying from 3.7 to 10.7kg /ha (of product) on target species of mulga (Acacia aneura), ironwood (A. estrophiolata) and witchetty bush (A. kempeana). Control of all species was achieved but the desirable combination of low effective rates and good pasture response made only ironwood control economic. Initial effects included a complete denuding of all vegetation on some occasions, the duration of which appeared to be related to the application rate, rainfall /time and soil type. At the ironwood sites following good summer rain, standing pasture biomass on the treated sites exceeded that of the controls by up to 4 times.
