Description

Halosulfuron Methyl CAS NO 100784-20-1 is a selective, post-emergence sulfonylurea herbicide. It is valued for its high efficacy at low application rates and its favorable environmental profile. This compound is essential for agricultural professionals and formulators seeking reliable weed control in key crops such as corn, sugarcane, and turf.

Application

• Selective Weed Control in Corn: Primarily used for the post-emergence management of broadleaf weeds and certain grasses in field corn and sweet corn.
• Sugarcane Herbicide: Effectively controls problematic weeds like sedges and broadleaf species in sugarcane plantations.
• Turf and Lawn Management: Applied in professional turf settings, including golf courses and sports fields, for selective weed eradication.
• Rice Paddy Applications: Used in some regions for weed control in rice, targeting specific weed spectra.
• Agricultural Formulations: Serves as the active ingredient in the manufacture of various commercial herbicide formulations, including wettable powders (WP) and dispersible granules (WG).
• Industrial Vegetation Management: Employed in non-crop areas for managing unwanted vegetation.

Quality Control

Our Halosulfuron Methyl is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for assay and impurity profiling, to ensure it meets high-purity standards suitable for agrochemical formulation. A comprehensive Certificate of Analysis (COA) is provided with each shipment to guarantee consistency and traceability.

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). Keep away from heat, sparks, and open flame. The product is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent moisture absorption.
