Description

Paraquat is a fast-acting, non-selective contact herbicide and desiccant, widely recognized for its potent herbicidal activity. Its primary value lies in its rapid action and effectiveness against a broad spectrum of weeds, making it a critical tool for agricultural and industrial vegetation management. This compound is essential for professionals in agriculture, horticulture, and land management who require reliable and efficient weed control solutions. Paraquat CAS NO 4685-14-7 is formulated for professional use under strict safety protocols.

Application

• Agricultural Weed Control: Used as a non-selective herbicide for pre-planting or pre-emergence weed control in various crops, including soybeans, corn, and cotton.
• Desiccation and Crop Drying: Applied as a desiccant to dry out crop foliage (e.g., potatoes, sunflowers) to facilitate mechanical harvesting.
• Orchard and Vineyard Management: For weed control in tree and vine crops, managing vegetation in the inter-rows without damaging the permanent crops.
• Industrial Vegetation Management: Control of weeds on non-crop areas such as railway embankments, industrial sites, and around utilities.
• Pasture Renovation: Used to clear existing vegetation in pastures before reseeding with desirable forage species.
• Aquatic Weed Management: In specific regulated formulations for controlling invasive aquatic weeds in canals and waterways.
