Description

S-Metolachlor Cga 50720 is a high-purity, chiral form of the widely used chloroacetamide herbicide metolachlor, specifically the S-enantiomer which exhibits superior herbicidal activity. This compound is critical for the development of more efficient and environmentally sustainable pre-emergence weed control solutions in modern agriculture. It is an essential technical-grade active ingredient for agrochemical manufacturers formulating selective herbicides for crops such as corn, soybeans, and peanuts.

Application

• Primary Active Ingredient (AI) in selective, pre-emergence herbicide formulations.
• Weed control in major field crops including maize (corn), soybeans, sorghum, and peanuts.
• Targeting of annual grasses and broadleaf weeds such as foxtails, barnyard grass, crabgrass, and black nightshade.
• Used in the synthesis of advanced, enantiomerically pure agrochemical intermediates.
• Technical material for manufacturing emulsifiable concentrates (EC), suspension concentrates (SC), and granular formulations.
• Research and development of new, reduced-rate herbicide products for integrated pest management (IPM) programs.
