Chlorimuron-ethyl is a member of sulfonylurea herbicides used wildly for pre- and post-emergence control of broad-leaved weeds in soybeans, maize, peanuts, beans, and other crops. It is characterized by very low application rates, high herbicidal activity, good crop selectivity, and low toxicity.

Chlorimuron-ethyl is an acetolactate synthase (ALS) inhibitor, that acts by inhibiting the biosynthesis of the essential amino acids like valine, leucine, and isoleucine. This stops the plant growth as cell division of growing roots and shoots tips are inhibited.

Application

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques. Chlorimuron-ethyl CRM may also find following uses:

• To develop and validate an RP-HPLC method for the determination of metsulfuron-methyl, chlorantraniliprole, and chlorimuron-ethyl residues in stems of Oryza sativa
• To study the rate of biodegradation of chlorimuron-ethyl using Pseudomonas sp. LW3 in liquid culture and contaminated soil
• To investigate the toxicological effects of chlorimuron-ethyl, cadmium, and copper on germination rate and shoot and root elongation of wheat Triticum aestivum
• Study the effect of chlorimuron-ethyl on physiological mechanisms in wheat and identify valuable biochemical biomarkers for the pollution of chlorimuron-ethyl in soil-plant systems
• Study the biochemical responses to joint stress of chlorimuron-ethyl and cadmium in wheat Triticum aestivum
• To study the photolysis of chlorimuron-ethyl on a soil surface, under sunlight and UV light
• To determine the photodegradation kinetics of chlorimuron-ethyl in an aqueous solution under sunlight and UV light
