Description

Pirimiphos-Methyl CAS NO 29232-93-7 is a highly effective organophosphate insecticide and acaricide, valued for its broad-spectrum activity and residual control. It is a critical tool for protecting stored commodities and public health by targeting a wide range of insect pests. This product is essential for manufacturers of agricultural formulations, public health insecticides, and pest control operators in the grain storage and vector control industries.

Application

• Stored Product Protection: Primary use for controlling beetles, weevils, moths, and mites in stored grains, cereals, and other durable commodities.
• Public Health Vector Control: Formulated for use against mosquitoes, flies, and other disease-carrying insects in indoor residual spraying (IRS) and other public health programs.
• Agricultural Crop Protection: Used as a foliar spray or soil treatment on a variety of crops, including fruits, vegetables, and ornamentals, to manage sucking and chewing pests.
• Animal Health: Incorporated into ectoparasiticide formulations for controlling lice, ticks, and mites on livestock and poultry.
• Structural Pest Management: Applied for the control of cockroaches, ants, and other crawling insects in and around buildings.
• Seed Treatment: Used to protect seeds from soil-borne insect pests during germination and early plant growth.
