Syngenta Submits New Herbicide for Regulatory Review
2 May 2013 
Syngenta announced it recently submitted petitions to the U.S. EPA and the Canadian Pest Management Regulatory Agency for the approval of mesotrione herbicide use on MGI herbicide-tolerant soybeans, which provide tolerance to three herbicide active ingredients: mesotrione, glufosinate and isoxaflutole.
When 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 said it will offer mesotrione in mixtures that deliver 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 said.
“When used together, mesotrione and MGI herbicide-tolerant soybeans will improve productivity and sustainability,” said Brett Miller, technical product lead, Syngenta.
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. It expects the soybeans will be available in the latter part of the decade. Additionally, MGI herbicide-tolerant soybeans will be out-licensed to other seed companies to include in their branded seed, according to Syngenta.
