Soybean growers are one step closer to achieving season-long, pre- and post-emergence weed control with a chemistry they’re accustomed to using in corn. Syngenta recently submitted petitions to the U.S. Environmental Protection Agency and the Canadian Pest Management Regulatory Agency for the approval of mesotrione herbicide use on MGI herbicide-tolerant soybeans.
The MGI herbicide-tolerant soybeans will provide tolerance to three herbicide active ingredients: mesotrione, glufosinate and isoxaflutole. MGI herbicide-tolerant soybeans are also under regulatory review in the U.S. and Canada as well as in key soybean importing countries, including the European Union. The soybeans will be available in the latter part of the decade, Syngenta announced. MGI herbicide-tolerant soybeans will be out-licensed to other seed companies to include in their branded seed once registration is recieved.
When mesotrione is applied to MGI herbicide-tolerant soybeans, mesotrione will provide a new tool for soybean growers, offering pre- and post-emergence control of weeds such as waterhemp, Palmer pigweed and common lambsquarters.
“Syngenta will offer mesotrione in mixtures that deliver robust, multiple modes of action. The mixtures will also incorporate overlapping efficacy with residual control to help mitigate the evolution of herbicide-resistant weeds,” the company announced.
“When used together, mesotrione and MGI herbicide-tolerant soybeans will improve productivity and sustainability,” said Brett Miller, technical product lead, Syngenta. “This powerful combination will offer soybean growers the same, flexible weed management program they’ve been accustomed to in corn for more than a decade.”
