Description

Metsulfuron is a systemic sulfonylurea herbicide known for its high potency and selectivity. It is valued for its effective control of a broad spectrum of broadleaf weeds and some grass weeds at very low application rates. This product is essential for agricultural professionals and formulators in the crop protection industry seeking reliable and efficient weed management solutions. Metsulfuron CAS NO 69635-63-8 is a key active ingredient for manufacturing professional-grade herbicide formulations.

Application

• Selective Herbicide Formulations: Primary use as an active ingredient in post-emergence herbicide products for cereal crops like wheat, barley, and oats.
• Broadleaf Weed Control: Effective against problematic weeds such as chickweed, mayweed, cleavers, and mustard species in grain fields.
• Non-Crop Area Management: Used in industrial vegetation management for areas like railways, roadsides, and utility rights-of-way.
• Turf and Pasture Management: Applied in certain turfgrass species and pastures for control of invasive broadleaf weeds.
• Forestry Applications: Utilized in silviculture for site preparation and release treatments in conifer plantations.
• Manufacturing of Premixes: A key component in combination herbicide products mixed with other active ingredients for broader spectrum control.

Quality Control

Our Metsulfuron technical material is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, to ensure it meets high-purity specifications typical for agrochemical active ingredients. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications and industry standards.

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 absorption of atmospheric moisture. Keep away from heat, sparks, and open flame.
