Description

Tribenuron is a selective, systemic sulfonylurea herbicide belonging to the chemical class of sulfonamides. It is valued for its post-emergence control of a broad spectrum of broadleaf weeds in cereal crops, offering effective weed management with favorable crop safety. This compound is a critical active ingredient for agricultural formulators and producers serving the global cereal farming industry. Its reliable performance makes it a key component in modern integrated pest management programs.

Application

• Primary Use in Cereal Herbicides: Formulated as a key active ingredient in post-emergence herbicides for wheat, barley, oats, and rye.
• Broadleaf Weed Control: Effective against problematic weeds such as chickweed, mayweed, cleavers, and mustard species.
• Agricultural Formulations: Used in the manufacturing of wettable powders (WP), water-dispersible granules (WG), and soluble liquid (SL) formulations.
• Crop Protection Programs: Integrated into resistance management strategies by rotating with herbicides of different modes of action.
• Non-Crop Areas: Occasionally used for vegetation management in industrial sites and right-of-ways, subject to local regulatory approval.
• Research & Development: Serves as a reference standard and intermediate in agrochemical research for developing new crop protection solutions.

Quality Control

Our Tribenuron technical material is produced under a strict quality management system to ensure batch-to-batch consistency and efficacy. Quality is verified through comprehensive analytical testing, including HPLC for assay and impurity profiling, to meet typical technical grade specifications. A Certificate of Analysis (COA) detailing purity, related substances, and physical parameters is provided with each shipment. We support compliance with global agricultural regulatory frameworks.

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 exclude moisture. Keep away from heat, sparks, and open flame. Store separately from strong acids, bases, and foodstuffs.
