Bayer CropScience and Syngenta have submitted applications for the approval of a new herbicide-tolerant soybean trait in various countries including the U.S., EU, and Canada. The trait confers tolerance to three herbicide active ingredients: mesotrione, glufosinate-ammonium and isoxaflutole (MGI). This MGI herbicide tolerance trait will be a tool for growers whose yields are affected by waterhemp, Palmer pigweed and lambsquarters.
The MGI herbicide tolerance trait will be available in NK brand soybean varieties offered by Syngenta and also in Bayer branded varieties as well as out-licensed to other seed brands once all the necessary regulatory approvals have been obtained. Additionally, each company is developing its own soybean herbicide products and programs that will be utilized with the new soybean varieties.
The new trait will broaden the herbicide options available to soybean growers where resistance has occurred within HPPD inhibitor products.
MGI herbicide tolerance will open the doors for consistent, market-leading residual weed control combined with a post-emergence control option to soybean growers according to a press release by Bayer and Syngenta. This technology will substantially improve soybean productivity and sustainability of weed control practices by enabling growers to use more effective, residual herbicides that offer maximum flexibility.
“Bayer CropScience is excited to work with Syngenta to provide growers a powerful new weed management tool in soybeans,” said Tim Zurliene, Global Trait Marketing and Licensing Manager, Bayer CropScience. “This new trait and herbicide system will enable growers to build highly effective weed management programs in soybeans while utilizing rotation of multiple and highly effective herbicide modes of action-critical in the ongoing fight against weed resistance.”
Brett Miller, Technical Product Lead, Syngenta says, “We expect MGI herbicide tolerance to become the foundation for soybean products containing stacked herbicide tolerance traits offering multiple modes of action to control the broadest spectrum of weeds.”
