The importance of understanding; weed species present, control options available and proper application timing are presented as essential elements in achieving maximum economic yield. Recent research results on the role of adjuvants, ammonium sulfate, water volumes and droplet sizes in improving control and reducing costs will be reviewed.enAttribution-NonCommercial-NoDerivs 2.5 CanadaMaximum economic yield as related to weed populations and herbicide usePresentation
