Description

Azimsulfuron is a selective, systemic sulfonylurea herbicide belonging to the acetolactate synthase (ALS) inhibitor class. This compound is valued for its high efficacy at low application rates and its favorable environmental profile, offering reliable post-emergence weed control. It is primarily required by agricultural chemical formulators and producers serving the rice cultivation sector, as well as researchers in agrochemical development.

Application

Azimsulfuron is a key active ingredient in modern agricultural practices, specifically designed for selective weed management.

• Primary Use in Rice Paddies: Post-emergence control of a broad spectrum of annual and perennial broadleaf weeds and sedges in transplanted and direct-seeded rice.
• Weed Spectrum: Effective against problematic weeds such as barnyardgrass, sedges (Cyperus spp.), and various broadleaf weeds that compete with rice crops.
• Formulation Base: Used in the manufacture of wettable powder (WP), water-dispersible granule (WG), and suspension concentrate (SC) herbicide formulations.
• Integrated Weed Management (IWM): A component in rotational herbicide programs to manage and delay herbicide resistance.
• Research & Development: Serves as a reference standard or active ingredient for analytical testing, bioassay studies, and the development of new agrochemical products.
