Mesotrione (Callisto, Camix, and Lumax), foramsulfuron (Option), and dicamba + diflufenzopyr (Distinct) are active ingredients that are being evaluated for potential registration on sweet corn. Camix and Lumax would provide new preemergence broadleaf weed control options in sweet corn. Callisto and Distinct would be alternatives to other postemergence broadleaf herbicides. Option would provide a similar spectrum of postemergence grass weed control as Accent. Crop injury is a concern with any new herbicide and this includes sweet corn. In addition, sweet corn hybrids have shown differential tolerance to certain herbicides. Consequently, we evaluated sweet corn tolerance to these three herbicides with two or more hybrids. A summary of the treatments, differential hybrid injury, and yields are provided on the following pages.
