Description

Diquat Dibromide CAS NO 85-00-7 is a quaternary ammonium salt widely recognized as a fast-acting, non-selective herbicide and desiccant. Its primary value lies in its rapid action and effectiveness as a contact herbicide, which makes it a critical tool for pre-harvest crop management and vegetation control. This compound is essential for agricultural professionals, industrial vegetation managers, and formulators in the agrochemical industry seeking reliable crop desiccation and burndown solutions.

Application

• Pre-Harvest Desiccation: Used to dry out crops like potatoes, sunflowers, and seed crops to facilitate uniform harvesting.
• Non-Selective Herbicide: Applied for broad-spectrum control of emerged weeds and grasses in agricultural and non-crop areas.
• Aquatic Weed Management: Employed for controlling floating and submerged vegetation in irrigation canals, ponds, and lakes.
• Industrial Vegetation Control: Used for managing weeds along railways, roadways, and utility rights-of-way.
• Chemical Fallow and Burndown: Facilitates no-till farming practices by clearing existing vegetation prior to planting.
• Agrochemical Formulation: Serves as a key active ingredient in the manufacturing of various liquid herbicide concentrates.

Quality Control

Our Diquat Dibromide is manufactured under strict quality management systems to ensure batch-to-batch consistency and efficacy. The product undergoes rigorous analytical testing, including assay by HPLC and verification of key impurity profiles, to meet technical and formulated product grade specifications. A Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters is provided with every shipment to guarantee compliance with your formulation 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product stability and handling properties.
