Description

trans-Deltamethrin is a highly potent synthetic pyrethroid insecticide, representing the most biologically active isomer of deltamethrin. Its exceptional efficacy at low application rates makes it a cornerstone for modern pest management programs, offering a powerful solution for controlling a broad spectrum of insect pests. This product is essential for manufacturers of professional agricultural and public health insecticides targeting markets in crop protection, stored product protection, and vector control.

Application

• Agricultural Insecticides: Formulated for foliar application to control lepidopteran, coleopteran, and other pests in crops such as cotton, soybeans, fruits, and vegetables.
• Public Health Products: A key active ingredient in formulations for mosquito control, including indoor residual sprays (IRS) and insecticide-treated nets (ITNs) for malaria prevention.
• Stored Grain Protection: Used to protect cereals, pulses, and other commodities from infestation by beetles, moths, and weevils during storage.
• Animal Health: Incorporated into ectoparasiticide products for livestock to control ticks, lice, and flies.
• Structural Pest Control: Effective in professional pest management for controlling cockroaches, ants, and other crawling insects in commercial and residential settings.
• Wood Preservation: Applied in treatments to protect timber and wood products from wood-boring insects.
