USA - Kyro™ herbicide brings game-changing postemergence weed control

Tennessee retailer Wes Bradley saw the benefits of new Kyro™ herbicide firsthand when he trialed the solution on 1,200 customer corn acres last season. 

″We have a lot of resistant weeds — both grasses and broadleaves — that we’re trying to control,″ says Bradley, who works for Nutrien Ag Solutions and manages two retail locations in western Tennessee. ″Finding a product that can help us with resistance issues and keep our crop clean is very important.″

Kyro herbicide is a premix solution with three effective modes of action for both postemergence and residual control on the toughest broadleaf and grass weeds. The strong in-season postemergence activity and residual of Kyro herbicide complements existing preemergence corn herbicides, making it a perfect fit into a two-pass program approach.

Bradley checked fields with his customers two weeks after applying Kyro herbicide and was impressed with the results.

″Before spraying Kyro, we had a mess of weeds,″ he says. ″When we went back and looked at the fields, everything was controlled and there weren’t any new breakthroughs either.″

Here’s a rundown of three key features and benefits of Kyro herbicide:

• Unique postemergence solution. Kyro herbicide is the first corn solution to combine the three proven active ingredients acetochlor, clopyralid and topramezone in a single premix for both contact and residual weed control. When used in a program approach, Kyro herbicide helps prevent and mitigate weed resistance by offering three effective modes of action.

• Unmatched broadleaf and grass control. Kyro herbicide controls more than 65 of the most difficult, resistant weed varieties, delivering industry-leading grass control, as well as exceptional broadleaf control.

• Ultimate versatility. Kyro herbicide has the versatility to easily fit into a most current weed control and agronomic programs. The new solution can be applied postemergence on corn up to 24 inches tall; can be tank-mixed with a wide variety of other products, including herbicides, insecticides and fungicides; and can be applied to several different types of corn, such as field corn (conventional and GMO), seed corn, silage and popcorn.
