Description

Chlorpyrifos-Methyl CAS NO 5598-13-0 is an organophosphate insecticide belonging to the chemical class of phosphorothioates. It is valued for its broad-spectrum activity against a range of insect pests in stored grains and other commodities. This product is essential for agricultural and post-harvest protection programs, helping to ensure food security and reduce economic losses.

Application

• Post-Harvest Grain Protection: Primary use for controlling beetles, weevils, and moths in stored cereals like wheat, rice, corn, and barley.
• Seed Treatment: Applied to protect seeds from soil-borne and storage pests prior to planting.
• Public Health Pest Control: Used in specific vector control programs, often in professional formulations.
• Structural Pest Management: For the protection of stored commodities in warehouses, silos, and food processing facilities.
• Agricultural Crop Protection (where registered): Used on certain field crops to control sucking and chewing insects.
