Kyro Herbicide

Novel formulation

with strong post weed control, greater versatility and excellent crop safety

 Kyroherbicide is a novel post-emergence solution that provides powerful control of more than 60 of the toughest broadleaf and grass weeds in cornfields. 

Kyro is a new premix solution with three effective modes of action for both post-emergence and residual control on broadleaf and grass weeds. In addition to strong broad-spectrum weed control, Kyro will offer farmers versatility to fit a wide variety of agronomic programs. Farmers will be able to apply Kyro up to 24-inch tall corn, giving them application timing flexibility and making it a perfect fit for a two-pass program. Plus, farmers will have the flexibility to apply Kyro on several different types of corn. The excellent crop safety in Kyro will help optimize yield potential, while still delivering outstanding tank-mix compatibility and additional handling attributes.
