FMC Corp. has a new broad-spectrum herbicide available.
Authority Assist herbicide, containing the active ingredients sulfentrazone and imazethapyr, offers a new option for broad-spectrum control of broadleaf weeds, including small-seeded weeds, with grass control assistance in soybeans. This will result in a cleaner start for increased yields.
The herbicide provides more effective control of many resistant biotypes, making it an important tool for an overall resistance management program in soybeans, says FMC. Its unique dual mode of action makes Authority Assist a key herbicide to provide more complete residual control of tough weeds and grasses and widen the window of application for the postemergence application.
Authority Assist is a flexible weed control option in soybeans. Growers can apply Authority Assist pre-plant, PPI or PRE in no-till, minimum-till or conventional tillage systems. To get a head start on planting, growers can apply Authority Assist in the fall or as a pre-plant application in early spring. The broad-spectrum label means growers can achieve more consistent control of broadleaves and grasses, resulting in higher yields.
