Imazapic (e.g. Plateau) belongs to which category of herbicides?

• A. ALS-Inhibitor
• B. Microtubule assembly inhibitor
• C. Growth regulator
• D. EPSPS inhibitor

Answer: (A)

Imazapic, commonly known by the trade name Plateau, is classified as an ALS-inhibitor herbicide. The ALS enzyme, or acetolactate synthase, is crucial for the synthesis of essential amino acids in plants. By inhibiting this enzyme, imazapic effectively disrupts the production of amino acids, leading to the targeted plants' inability to grow and ultimately resulting in their death. This mode of action is characteristic of the ALS-inhibitor category, making it a powerful tool for controlling a variety of weed species. The other categories mentioned do not apply to imazapic. Microtubule assembly inhibitors target the structure involved in cell division, growth regulators affect hormone balance, and EPSPS inhibitors target a different enzymatic pathway involved in amino acid synthesis, but through a distinct mechanism. Therefore, recognizing imazapic as an ALS-inhibitor is crucial for understanding its usage and effectiveness in weed management strategies.
