Imazethapyr 10% SL

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.

Description

Mode of action

  • AHAS (ALS) Inhibitor: Blocks the synthesis of valine, leucine, and isoleucine, essential amino acids required for plant growth, leading to weed death.
  • Systemic Action: Rapidly absorbed through leaves and roots, translocated throughout the plant for effective pre- and post-emergence control.

Benefits

  • Controls a broad spectrum of annual and perennial weeds.
  • Provides both pre-emergence and early post-emergence weed control.
  • Long residual activity reduces the need for multiple applications.
  • Selective action ensures crop safety with minimal phytotoxicity.
  • Enhances crop yield by reducing weed competition effectively.
