Kyro herbicide is a novel postemergence corn herbicide that delivers powerful weed control for farmers, along with corn crop and application versatility and excellent crop safety. Kyro is a premix solution with three effective modes of action for both contact and residual control on the toughest broadleaf and grass weeds. Part of a two-pass program in traited or conventional corn, Kyro offers famers flexibility on application timing on up to 24-inch corn and versatility to customize weed control programs to fit their fields. With its excellent crop safety, Kyro promotes a healthier crop for higher yield potential.  


Novel formulation

Kyro is the first corn herbicide to combine the three proven modes of action of acetochlor, clopyralid and topramezone is a single premix for both contact and residual control of more than 65 of the toughest broadleaf and grass weeds.

Strong post weed control

The strong in-season postemergence activity and residual of Kyro complements farmers’ existing preemergence corn herbicides, making it a perfect fit into a two-pass program approach. Kyro gives farmers another powerful solution outside of glyphosate and ALS herbicides in the fight to control resistant grasses.

Greater versatility

Kyro fits a wide variety of different types of corn – glyphosate-tolerant, non-GMO, seed and popcorn. It has the flexibility as a stand-alone herbicide and as a tankmix partner with glyphosate, atrazine and other corn herbicides, which gives farmers the option to customize their weed management program. Plus, farmers can apply Kyro up to 24-inch-tall corn, giving them application timing flexibility.
