Description

1S,3S,αs-Deltamethrin is a highly potent and specific stereoisomer of the synthetic pyrethroid insecticide deltamethrin. This compound is valued for its exceptional insecticidal activity and targeted efficacy, offering a powerful tool for integrated pest management. It is primarily required by manufacturers in the agrochemical industry for formulating advanced crop protection products, as well as by producers of professional and public health insecticides targeting a wide range of pests.

Application

• Agricultural Insecticides: A key active ingredient in formulations for protecting a broad spectrum of crops, including cotton, cereals, fruits, and vegetables, from lepidopteran, coleopteran, and other insect pests.
• Public Health Vector Control: Used in products for mosquito control programs to combat malaria, dengue, and other vector-borne diseases, often in indoor residual sprays (IRS) and treated materials.
• Professional Pest Management: Incorporated into solutions for controlling pests in stored grains, warehouses, and food handling facilities.
• Animal Health: Found in ectoparasiticide formulations for livestock, protecting against ticks, lice, and flies.
• Specialty Non-Crop Uses: Applied in situations requiring high knockdown and residual activity against resistant pest populations.
