Description

Sulfometuron-Methyl is a selective, systemic sulfonylurea herbicide known for its high activity at low application rates. This compound is critical for effective, long-lasting control of a broad spectrum of broadleaf weeds and grasses in non-crop and industrial areas. It is primarily utilized by professional formulators and agricultural chemical manufacturers serving the forestry, utility rights-of-way, and industrial vegetation management sectors.

Application

• Forestry Management: Used for site preparation and conifer release to control competing vegetation in timber plantations.
• Industrial Vegetation Control: Essential for maintaining weed-free conditions along utility lines, railroads, highways, and pipeline rights-of-way.
• Non-Crop Area Management: Applied in areas such as storage yards, industrial complexes, and around farm buildings for total vegetation control.
• Agricultural Use: Registered for use in certain crops like sugarcane and turf, providing pre- and post-emergence weed control.
• Chemical Manufacturing: Serves as a key active ingredient for formulators producing professional-grade herbicide solutions.

Quality Control

Our Sulfometuron-Methyl is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. The product is tested against established analytical specifications to confirm identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your technical requirements.

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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect stability and performance.
