Description

Mode of Action

Metsulfuron methyl specifically inhibits the enzyme acetolactate synthase (ALS), also known as acetohydroxyacid synthase (AHAS). ALS is involved in the biosynthesis of branched-chain amino acids (valine, leucine, and isoleucine), which are crucial for protein synthesis. By inhibiting ALS, metsulfuron methyl disrupts the production of these essential amino acids, resulting in the accumulation of toxic metabolites and the impairment of protein synthesis. This leads to growth inhibition, chlorosis (yellowing), and ultimately the death of the target weeds. Metsulfuron methyl’s systemic mode of action ensures that the herbicide is distributed throughout the entire plant, reaching even hard-to-reach areas such as underground rhizomes or tubers. This characteristic makes it effective against both emerged and underground portions of perennial weeds.
