Description

Bensulfuron CAS NO 99283-01-9 is a selective, systemic sulfonylurea herbicide. It is valued for its high efficacy at low application rates and its excellent crop safety profile in specific agricultural systems. This compound is primarily required by agrochemical formulators and agricultural producers for the pre- and post-emergence control of broadleaf weeds and sedges in key crops such as rice and wheat.

Application

• Rice Herbicide: Selective control of broadleaf weeds, sedges, and certain grasses in transplanted and direct-seeded rice paddies.
• Wheat and Barley Protection: Used in formulations for the post-emergence management of problematic weeds in cereal crops.
• Agrochemical Formulation: A key active ingredient in the manufacturing of wettable powders (WP), water-dispersible granules (WG), and suspension concentrates (SC).
• Turf and Ornamental Management: Employed in professional turf management and ornamental horticulture for selective weed control.
• Industrial Vegetation Control: Used in non-crop areas for total vegetation management, often in combination with other herbicides.
• Research & Development: Serves as a reference standard and biochemical tool in agricultural research for studying sulfonylurea mode of action and resistance mechanisms.

Quality Control

Our Bensulfuron is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for assay and impurity profiling, to ensure it meets precise technical or analytical standard grade specifications. A comprehensive Certificate of Analysis (COA) detailing purity, related substances, and physical parameters is provided with each shipment to guarantee consistency and reliability for your formulation and research needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and handling properties.
