A new option for broad-spectrum control of broadleaf weeds with grass control assistance in soybeans is now available from FMC Corporation.
New Authority Assist herbicide is available for residual control of tough broadleaves and grass control assistance. Soybean growers can use Authority Assist for complete broadleaf control, including control of small-seeded weeds, and grass assist, resulting in a cleaner start for increased yields.
Authority Assist is labeled for control of a variety of key weeds, including waterhemp, lambsquarters, pigweed, cocklebur, velvetleaf, Venice mallow, nightshade, morning-glory, nutsedge, kochia, Russian thistle, barnyardgrass, foxtail and fall panicum.
In addition, Authority Assist provides effective control of many resistant biotypes, making it an important tool for an overall resistance management program in soybeans.
A unique dual mode of action with Authority Assist provides more complete residual control of tough weeds and grasses and widens the window of application for the postemergence application.
Authority Assist is a flexible weed control option in soybeans. Growers can apply Authority Assist preplant, 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 preplant application in early spring. The broad-spectrum label means growers can achieve more consistent control of broadleaves and grasses, resulting in higher yields.
“Authority Assist provides soybean growers effective residual control of tough broadleaf weeds and grass assist in one convenient product,” says Yemel Ortega, product manager for FMC. “Authority Assist provides control of problematic weeds, allowing growers more flexibility in post application timing and contributing to maximize soybeans yields.”
Authority Assist can be applied as a tank-mix with other herbicides for more broad-spectrum control of emerged weeds and grasses in fall burndown and spring preplant treatments. Usage rates for Authority Assist vary from 4 ounces per acre to 12 ounces per acre, depending on level of weed pressure.
