The material shall consist of nicosulfuron together with relatedmanufacturing impurities and shall be a homogeneous white crystalline or powdersolid, free from visible extraneous matter and added modifying agents. Nicosulfuron is a kind of herbicides belonging to thesulfonylurea family. It is a broad-spectrum herbicide that can controls manykinds of maize weeds including both annual weeds and perennial weed includingJohnsongrass, quackgrass, foxtails, shattercane, panicums, barnyardgrass,sandbur, pigweed and morningglory. It is a systemic selective herbicide, beingeffective in killing plants near the maize. This selectivity is achievedthrough maize capability of metabolizing Nicosulfuron into harmless compound.Its mechanism of action is through inhibiting the enzyme acetolactate synthase(ALS) of the weeds, blocking the synthesis of amino acids such as valine andisoleucine, and finally inhibiting the protein synthesis and causing death ofweeds.
A Special systematic selective post-emergence herbicide for maize. It worksby being absorbed through the weeds, stem leaf and root and conducting in theplant.
