Description

Hexazinone is a selective, systemic herbicide belonging to the triazinone chemical class. It is valued for its broad-spectrum, long-lasting control of a wide range of annual and perennial grasses, broadleaf weeds, and woody plants. This non-selective herbicide is a critical tool for industrial vegetation management, particularly in forestry, non-crop areas, and for total vegetation control on sites like utility rights-of-way, railroads, and industrial yards. Hexazinone CAS NO 51235-04-2 is formulated as water-soluble granules or liquid concentrates for professional application.

Application

• Forestry Site Preparation and Release: Used for conifer release and site preparation to control competing vegetation in pine, fir, and spruce plantations.
• Industrial Vegetation Management (IVM): Essential for maintaining clear zones along power lines, pipelines, highways, and railroad tracks by preventing woody plant encroachment.
• Non-Crop Area Weed Control: Applied in storage yards, around industrial facilities, and under fences for total vegetation suppression.
• Sugarcane and Pineapple Crops: Registered for selective weed control in certain sugarcane and pineapple production systems.
• Rangeland and Pasture Improvement: Used to manage brush and unwanted woody species to improve forage quality for livestock.
• Aquatic Weed Management: Certain formulations are approved for controlling emergent weeds in specific aquatic sites.

Quality Control

Our Hexazinone technical material and formulations are produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay by HPLC and impurity profiling, to ensure it meets defined specifications for purity, solubility, and physical properties. Certificates of Analysis (COA) are provided with each shipment, and we support compliance with global regulatory standards such as EPA and EU pesticide regulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Maintain storage temperature between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent moisture absorption and contamination.
