Corteva Agriscience's Kyro Postemergence Corn Herbicide is the first product on the market to combine the active ingredients acetochlor, topramezone and clopyralid into one premix. 

Kyro herbicide will offer corn farmers several key benefits:

  • Powerful postemergence weed control: Kyro herbicide combines three effective modes of action for control of more than 65 of the most difficult, resistant weed species and can provide extended residual control at higher use rates. Kyro herbicide provides excellent control of waterhemp, Palmer amaranth, giant ragweed, marestail, barnyard grass, fall panicum and woolly cupgrass. 
  • Excellent crop safety: Kyro herbicide is formulated with an encapsulated acetochlor for excellent crop safety. Less crop response helps keep corn plants healthy until harvest for better yield potential.
  • Application flexibility: Kyro herbicide can be applied on corn up to 24 inches tall to fit a variety of management programs. It also can be used on traited and nontraited corn products, including seed and popcorn. 
  • Tank-mix compatibility: Kyro herbicide is compatible with a wide array of tank-mix partners, including atrazine, glyphosate, fungicides, insecticides and micronutrients. This allows farmers to fully customize their applications to their individual needs.
