Description

Diquat Ion CAS NO 2764-72-9 is the cationic component of the widely used herbicide Diquat Dibromide, a fast-acting, non-selective contact herbicide and desiccant. Its primary value lies in its rapid action and effectiveness as a harvest aid and for pre-harvest desiccation of various crops. This product is essential for agricultural professionals, industrial formulators, and research institutions involved in crop protection, aquatic weed management, and herbicide development.

Application

• Herbicide Formulation: Primary active ingredient in non-selective, contact herbicide formulations for broad-spectrum weed control.
• Pre-Harvest Crop Desiccation: Used as a harvest aid to desiccate potato vines, seed crops, and cotton, facilitating mechanical harvesting.
• Aquatic Weed Management: Effective for controlling floating and submerged weeds in irrigation canals, ponds, and other non-potable water bodies.
• Industrial Vegetation Control: Management of weeds on industrial sites, along railways, and under utility lines.
• Defoliant: Applied for the defoliation of certain crops prior to harvest.
• Research & Development: Serves as a key reference standard and intermediate in agrochemical research and analytical method development.
