Herbicide hard on kochia, easy on the crop rotations

Apr 11, 2023

Growers in the dark brown and brown soil zone have a new herbicide option designed to control kochia in cereals.

Corteva Agriscience’s OnDeck has a Group 6 (bromoxynil) and a Group 27 (tolpyralate), an active ingredient that is new to the western Canadian cereal market.

Jason Smith, Corteva’s western portfolio marketing manager for cereal herbicides, said OnDeck will be a valuable tool to help fight herbicide resistant kochia.

Essentially, all kochia on the Prairies is considered resistant to acetolactate synthase inhibitor and there are populations resistant to glyphosate, dicamba, and fluroxypyr.

Last summer, kochia resistant to PPO inhibitors may also have surfaced in Saskatchewan.

Video: Agriculture Secretary Rollins Speaks at American Farm Bureau Federation Convention in Anaheim

One of the highlights at the 2026 American Farm Bureau Federation Convention in Anaheim, California, was an address by U.S. Secretary of Agriculture Brooke Rollins. During her remarks, she thanked America’s farmers and ranchers and said the Trump Administration is fully aware that food security is national security.

She also acknowledged the challenging times in Farm Country with low commodity prices and high input costs and said that’s why the President stepped in to help with the recent Bridge Assistance Program.

Montana Farm Bureau Federation Executive Vice President Scott Kulbeck says that Farm Bureau members are appreciative of the help and looks forward to working with the American Farm Bureau Federation and its presence in Washington, DC to keep farmers and ranchers in business.

Secretary Rollins said the Trump Administration is also committed to helping ranchers build back America’s cattle herd while also providing more high-quality U.S. beef at the meat case for consumers.

And she also announced more assistance for specialty crop producers who only received a fraction of the $12 billion Farmer Bridge Assistance (FBA).

It’s important to note that producers who qualify for Farmer Bridge Assistance can expect the Farm Service Agency to start issuing payments in late February. For more information, farmers and ranchers are encouraged to contact their local USDA Service Center.
