Imazethapyr (Cat No.: R025204) is a broad-spectrum, systemic herbicide belonging to the imidazolinone class. It functions by inhibiting acetohydroxyacid synthase (AHAS), a key enzyme in the biosynthesis of branched-chain amino acids like valine, leucine, and isoleucine. This disruption halts cell division and plant growth. Imazethapyr is commonly used for pre- and post-emergence weed control in crops such as soybeans, peanuts, and dry beans. Its selectivity and low application rates make it environmentally favorable, though resistance management is crucial to maintain long-term efficacy.
