Description

Oxasulfuron is a selective, systemic sulfonylurea herbicide known for its high efficacy at low application rates. This compound is valued for its excellent post-emergence control of a broad spectrum of broadleaf and grassy weeds in key agricultural systems. It is primarily utilized by agrochemical formulators and manufacturers serving the global crop protection industry. Its reliable performance makes it a critical component in modern integrated weed management strategies.

Application

• Selective Weed Control in Soybeans: Post-emergence application for managing troublesome weeds in soybean crops.
• Cereal Crop Protection: Used in wheat and barley for control of resistant broadleaf weeds.
• Agrochemical Formulation: Serves as the active ingredient in the production of various herbicide formulations, including wettable powders (WP) and suspension concentrates (SC).
• Industrial Vegetation Management: Employed in non-crop areas for general vegetation control.
• Research & Development: Used as a reference standard and intermediate in agricultural chemical research.

Quality Control

Our Oxasulfuron is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including HPLC for assay and related substances. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with agreed specifications.

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 (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
