Nicosulfuron is a systemic, selective, and post-emergent herbicide from the sulfonylurea group that is widely used in the control of narrow-leaved weeds in corn fields. This pesticide is known for its low dosage, high efficacy, and good stability in the plant, and is considered one of the most effective selective herbicides for corn due to its rapid absorption and transfer.

How Nicosulfuron works?

Nicosulfuron inhibits the ALS enzyme (acetolactate synthase) and disrupts the biosynthesis of essential amino acids including valine, leucine and isoleucine. This disruption stops the growth of meristems and ultimately leads to yellowing, necrosis and, finally, the gradual death of the weed. The toxin is absorbed through the leaves and a small amount through the roots and moves rapidly through the xylem and phloem. Uses
Nicosulfuron is primarily used for the control of annual and perennial broadleaf weeds in corn. The most important target weeds include: Echinochloa Foxtail (Setaria spp.) Rice (Lolium spp.) Phalaris Johnsongrass species – seed and rhizome This herbicide is suitable for grain corn, forage corn and some resistant hybrid varieties.
