Nikogan

Nikogan is a selective post-emergence herbicide for maize, formulated as an oil dispersion containing 40 g/L nicosulfuron, a systemic sulfonylurea. Absorbed through foliage, it controls annual and perennial grass weeds — including couch grass and Johnson grass — plus some broadleaf weeds. Apply once by spraying at the 3–10 leaf stage of the crop, at 1.0–1.25 L/ha, targeting young weeds in warm weather between +14°C and +25°C.
