The mixture at 825 - 1 650 g a. i./hm^2 effectively controlled the main weeds. Control of Amaranthus retroflexus was excellent and that of Eleusine indica and Acalyphaaustralis was adequate however control of Digitaria sanguindalis was limited. At the dose range tested, the herbicide preparation was selective to corn.
