Benazolin is a herbicide belonging to the chemical class of triazolinones, widely used in agriculture to control grass weeds in cereal crops such as wheat and barley. It inhibits the enzyme acetolactate synthase (ALS), disrupting the biosynthesis of branched-chain amino acids essential for plant growth. By selectively targeting grass weeds while sparing broadleaf crops, benazolin provides effective weed control and ensures higher yields. Its systemic action within plant tissues and low environmental persistence make it an integral tool in sustainable weed management practices.
