Soybean farmers have a new solution to help control weeds in 2021. Kyber herbicide is a new preemergence, soybean residual from Corteva Agriscience. It has three effective modes of action, including a Group 15 active ingredient.

Farmers constantly seek new options to fight troublesome weeds like waterhemp, Palmer amaranth and common ragweed. They’ve been particularly vocal about wanting chemistries that include a Group 15 active ingredient to combat herbicide-resistant weeds. “As a preemergence herbicide, Kyber is an ideal addition to a program approach for weed control,” says Aaron Smith, U.S. product manager for soybean herbicides for Corteva.

Using a program approach means starting clean with either tillage or a burndown application, followed by preemergence and postemergence herbicides with multiple modes of action and long residual protection, Smith says. This program approach to weed control is key to controlling resistant weeds throughout the season and to preventing new herbicide resistance from developing.

“Kyber is a strong preemergence herbicide,” he adds, “and it fits into a program approach. It comes in a liquid premix and contains modes of action from groups 5 and 14, in addition to Group 15. What makes Kyber special is each mode of action in it is effective against resistant weeds. Together, they provide a comprehensive preemergence solution.”

Kyber also has extensive residual activity to keep fighting resistant weeds like waterhemp, Palmer amaranth and common ragweed long after application, says Smith. “The residual lasts four to six weeks, even going beyond six weeks in the right conditions. This creates a wide window for a postemergence application, creating flexibility if there are poor weather conditions or other delays. By controlling weeds early, young soybeans won’t have to waste energy by competing for nutrients and sunlight. This allows for maximum yield potential.”

Kyber herbicide will also be a strong fit for growers planting Enlist E3 soybeans, says Smith. The new solution will serve as a strong preemergence and can be followed by a planned postemergence application of Enlist Duo herbicide or a tank mix with Enlist One herbicide.

Enhancing field management

Smith says soybean farmers will be able to improve their field management with Kyber as part of the weed control program. Using several herbicide modes of action helps prevent weeds from becoming resistant to one specific mode of action in the future. “The three effective modes of action and extensive residual activity in Kyber will help do that,” he says.

“By working to prevent new resistance from developing, you are setting yourself up to maximize yield — not just for one season but also in the long term,” Smith says. “Kyber will help set you up for future success by keeping your fields clean.”
