Chlorimuron ethyl is a systemic herbicide belonging to the sulfonylurea herbicide group, widely used to control broadleaf weeds in various crops such as soybeans, peanuts, maize, and cotton.
It inhibits the enzyme acetolactate synthase (ALS), which is essential for the biosynthesis of branched-chain amino acids in susceptible weeds, ultimately leading to their death.
Chlorimuron ethyl is valued for its effectiveness at low application rates, long-lasting residual activity, and selective action against broadleaf weeds while being relatively safe for grass crops.
However, proper application techniques and stewardship practices are essential to minimize the risk of crop injury and environmental contamination.
