Halosulfuron-methyl（Cat No.:M007785） is a selective herbicide used extensively in agriculture to control broadleaf weeds and sedges in crops like corn, sugarcane, and turfgrass. It belongs to the sulfonylurea class, which works by inhibiting acetolactate synthase (ALS), an essential enzyme in the biosynthesis of branched-chain amino acids in plants. This inhibition leads to the cessation of cell division and plant growth, ultimately causing the death of the targeted weeds. Halosulfuron-methyl is favored for its effectiveness at low application rates and its minimal impact on the environment and non-target plant species when used as directed.
