Description

Bispyribac CAS NO 125401-75-4 is a selective, systemic herbicide belonging to the pyrimidinyloxybenzoic acid chemical class. This compound is valued for its post-emergence activity and effectiveness against a broad spectrum of grassy and broadleaf weeds in key agricultural systems. It is primarily required by agrochemical formulators and agricultural producers for integrated weed management programs. Its systemic action ensures thorough control, making it a critical tool for maintaining crop yield and quality.

Application

• Selective Herbicide in Rice Cultivation: Primary use for post-emergence control of barnyardgrass, sedges, and broadleaf weeds in paddy rice.
• Turf and Ornamental Management: Used in professional turf management for weed control in grasses.
• Agrochemical Formulation: A key active ingredient in the manufacture of suspension concentrates (SC) and other commercial herbicide formulations.
• Non-Crop Area Weed Control: Application in industrial sites and right-of-ways for vegetation management.
• Research & Development: Serves as a reference standard and biochemical tool in plant physiology and herbicide resistance studies.
• Seed Production: Used to ensure clean seed production fields by controlling problematic weeds.

Quality Control

Our Bispyribac is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. The product undergoes rigorous analytical testing, including HPLC for assay and impurity profiling, to meet technical-grade specifications. A Certificate of Analysis (COA) detailing purity, identity, and related substances is provided with each shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent degradation from atmospheric moisture.
