Description

Endothal Monohydrate is a selective, water-soluble herbicide and plant growth regulator derived from a dicarboxylic acid structure. Its primary value lies in its potent herbicidal activity, effectively controlling a wide range of aquatic weeds and certain broadleaf terrestrial species. This makes it a critical tool for industries requiring vegetation management in water bodies, irrigation systems, and specific agricultural settings. Professionals in aquatic management, agriculture, and industrial site maintenance rely on its consistent performance for sustainable vegetation control.

Application

• Aquatic Weed Control: Primary use for managing submerged and floating weeds in lakes, ponds, irrigation canals, and drainage ditches.
• Turf Management: Selective control of Poa annua (annual bluegrass) and other unwanted grasses in golf courses and high-value turf.
• Industrial Vegetation Management: Control of vegetation along railroad rights-of-way, highways, and utility lines.
• Agricultural Desiccant: Used as a harvest aid for crops like alfalfa and clover to dry down plants for easier harvesting.
• Research & Development: Serves as a standard or active ingredient in the formulation and testing of new herbicidal products.

Quality Control

Our Endothal Monohydrate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance. A Certificate of Analysis (COA) detailing the results for assay, moisture content, and related substances is provided with each shipment to guarantee traceability and compliance with industry standards.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
