About this product
Stellar is a systemic post-emergence herbicide for corn, combining topramezone (50 g/L), an HPPD inhibitor, with dicamba (160 g/L), a synthetic auxin, in a soluble liquid formulation. It controls a broad range of annual and perennial broadleaf weeds and annual grasses, including common milkweed and sunflower volunteers such as Clearfield and ExpressSun types. Apply at 0.8–1.25 L/ha with the Metolat adjuvant when corn has 3–8 leaves and weeds are young.
