Corteva Coreon Herbicide is a new-generation rice herbicide formulated with Penoxsulam 0.97% + Butachlor 38.8% SE. It is designed for broad-spectrum weed management in transplanted rice, helping farmers control important grasses, sedges and broadleaf weeds during the early crop stage.
Coreon offers a flexible application window from 0 to 7 days after transplanting, making it useful for rice farmers who need more practical timing flexibility compared to many conventional pre-emergence herbicides. When applied correctly, it helps reduce early weed competition and supports better rice crop establishment.
Early weed competition in transplanted rice can reduce nutrient availability, sunlight access and crop growth. Corteva Coreon helps manage weeds before they become a serious problem in the field. Its combination chemistry supports control of key weed groups and helps maintain a cleaner rice field during the critical early growth period.
