Description

Propanil CAS NO 709-98-8 is a selective post-emergence herbicide belonging to the anilide chemical class. It is valued for its effective control of a wide spectrum of grass and broadleaf weeds in key agricultural crops. This product is essential for agribusinesses, formulators, and distributors serving the global rice and wheat cultivation markets, where reliable weed management is critical for yield protection.

Application

• Selective Herbicide for Rice Paddies: Primary application for controlling barnyardgrass (Echinochloa crus-galli) and other weeds in transplanted and direct-seeded rice.
• Wheat and Barley Protection: Used for post-emergence weed control in cereal crops, targeting wild oats and other competitive weeds.
• Turf and Ornamental Management: Employed in professional turf management for selective weed control in certain grass species.
• Industrial Vegetation Control: Component in non-crop herbicide formulations for managing vegetation along rights-of-way and industrial sites.
• Agrochemical Formulation: Serves as a key active ingredient (a.i.) for manufacturers producing emulsifiable concentrate (EC) and other liquid formulations.
• Research & Development: Used as a reference standard and biochemical tool in agricultural research studying herbicide action and weed resistance.
