DowDuPont agricultural business Corteva Agriscience has applied to the US EPA to register its herbicide, florpyrauxifen-methyl (trade-marked as Rinskor), for use on pastures and rangeland. It would be the first new active ingredient for use in this sector for more than a decade, the company points out.
Florpyrauxifen-methyl would provide cattle farmers with a wider spectrum of broadleaf weed control than currently available, Corteva says. Many years of testing have demonstrated superior control of weeds such as wild carrot (Daucus carota), giant hogweed (Heracleum mantegazzianum), wild parsnip (Pastinaca sativa), poison hemlock (Conium maculatum) and common caraway (Carum carvi) and better late-season control of marshelder (Iva annua) and ironweed (Vernonia spp).
Favourable features of the herbicide include season-long residual control, safety to desirable forage grasses, low use rate, low-odour formulation and compatibility with dry and liquid fertilisers, Corteva notes. The company introduced florpyrauxifen-methyl in the US this year for use on rice as Loyant. It was recently given the American Chemical Society Green Chemistry Challenge award.Florpyrauxifen-methyl is expected to be the second of three products introduced to the US pasture and rangeland market. Corteva recently launched MezaVue (aminopyralid + picloram + fluroxypyr) for the control of annual and perennial broadleaf weeds and certain woody plants and vines for use in pastures, rangeland and non-crop areas.
