Description

Ethametsulfuron-Methyl CAS NO 97780-06-8 is a selective, systemic sulfonylurea herbicide belonging to the acetolactate synthase (ALS) inhibitor class. It is valued for its high efficacy at low application rates, offering cost-effective and targeted weed control in key agricultural crops. This product is essential for formulators and distributors serving the global agrochemical industry, particularly those focused on oilseed and vegetable crop protection programs.

Application

Ethametsulfuron-Methyl is primarily used as a post-emergence herbicide. Its key applications include:

• Oilseed Rape (Canola) Protection: Selective control of broadleaf weeds, such as cleavers, chickweed, and mayweed, in winter and spring oilseed rape.
• Vegetable Crop Weed Management: Used in crops like mustard, coriander, and certain leafy vegetables for managing competing weed species.
• Agrochemical Formulation: A key active ingredient for manufacturing wettable powder (WP), water-dispersible granule (WG), and suspension concentrate (SC) herbicide formulations.
• Industrial & Non-Crop Use: Potential application in forestry and industrial vegetation management programs, subject to local regulatory approvals.

Quality Control

Our Ethametsulfuron-Methyl is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, potency, and physical properties. A Certificate of Analysis (COA) documenting results for assay, related substances, moisture content, and other critical parameters is provided with each shipment to guarantee consistency and regulatory compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and handling properties. Keep away from heat, sparks, and open flame.
