Description

Dimethenamid-P is a high-purity, single-isomer active ingredient belonging to the chloroacetamide class of herbicides. This compound is valued for its superior herbicidal activity and environmental profile compared to its racemic counterpart, offering more effective weed control at lower application rates. It is primarily utilized by agrochemical manufacturers and formulators for the production of selective pre-emergence and early post-emergence herbicides. Key target crops include corn, soybeans, and other major field crops where control of annual grasses and broadleaf weeds is critical.

Application

• Active ingredient in selective pre-emergence herbicide formulations for field corn.
• Key component in early post-emergence herbicide products for soybean cultivation.
• Used in combination with other active ingredients for broad-spectrum weed control programs.
• Formulated into emulsifiable concentrates (EC), suspension concentrates (SC), and microencapsulated products.
• Applied for the management of key weed species including foxtails, barnyardgrass, black nightshade, and common ragweed.
• Integrated into sustainable agriculture practices due to its favorable environmental fate.
