Corteva Agriscience recently launched Kyber herbicide, a three-way liquid premix for soybeans, for the 2021 season. The preemergence soybean herbicide has three effective modes of action: metribuzin, a Weed Science Society of America Group 5; flumioxazin, a Group 14; and pyroxasulfone, a Group 15.
The premix offers strong control of some of the toughest weeds farmers face, including johnsongrass, barnyardgrass, Palmer amaranth, panicum, ryegrass and red rice, according to a news release. Each mode of action in Kyber herbicide controls resistant weeds individually. Combined, they provide a comprehensive solution. The herbicide also has extensive residual activity, lasting four to six weeks, even going beyond six weeks in the right conditions, according to the release.
A program approach to weed control – which uses burndown, preemergence and postemergence herbicides with multiple, effective modes of action and long residual activity – is key to keeping fields clean and helping prevent development of resistant weeds.
“Using several herbicide groups helps prevent weeds from becoming resistant to one specific mode of action in the future,” Aaron Smith, Corteva U.S. product manager for soybean herbicides, said in the release. “What sets Kyber herbicide apart is that it allows for better long-term field management to help maximize yield potential, not just for one season, but into the future.”
