Description

Clopyralid (2-Hydroxyethyl)Ammonium is a selective systemic herbicide formulated as an amine salt for enhanced stability and handling. This compound is valued for its high efficacy against a broad spectrum of broadleaf weeds, particularly in the Asteraceae, Fabaceae, and Solanaceae families. It is a critical agrochemical input for agricultural professionals and formulators seeking reliable, long-lasting residual weed control in key crops such as cereals, oilseed rape, and turf.

Application

• Selective Weed Control in Cereals: Primary use for post-emergence control of persistent weeds like thistles, mayweed, and cleavers in wheat, barley, and oats.
• Oilseed Rape Protection: Effective management of challenging weeds, including charlock and volunteer potatoes, in oilseed rape crops.
• Turf and Lawn Management: Used in professional turf management for controlling clover, dandelion, and other broadleaf weeds in grasses.
• Industrial Vegetation Management: Applied in non-crop areas such as railways, roadsides, and utilities for total vegetation control.
• Agrochemical Formulation: Serves as a key active ingredient for manufacturers developing proprietary herbicide blends and ready-to-use formulations.
• Forestry and Silviculture: Aids in site preparation and conifer release programs by controlling competing brush and broadleaf vegetation.

Quality Control

Our Clopyralid (2-Hydroxyethyl)Ammonium is manufactured under a strict quality management system to ensure batch-to-batch consistency and efficacy. Every lot is tested against rigorous in-house specifications for identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing assay results, physical properties, and relevant limits is provided with each shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. The container must be kept tightly closed in a dry environment to prevent moisture absorption.
