Imazethapyr 10% SL is a selective, systemic herbicide from the imidazolinone group, designed for the effective control of broadleaf and grassy weeds in soybean, groundnut, pulses, and other leguminous crops. It inhibits acetohydroxyacid synthase (AHAS), an essential enzyme in the biosynthesis of branched-chain amino acids, leading to disrupted protein synthesis and weed growth suppression. Its residual soil activity ensures prolonged weed control with minimal crop competition.
