Description

cis-Fenfluthrin is a synthetic pyrethroid insecticide known for its potent neurotoxic action against a broad spectrum of pests. Its high efficacy and photostability make it a valuable active ingredient for long-lasting crop protection and public health formulations. This compound is essential for manufacturers developing advanced insecticidal products for agricultural, vector control, and professional pest management applications.

Application

• As a key active ingredient in the formulation of agricultural insecticides for controlling lepidopteran, coleopteran, and other insect pests in crops like cotton, cereals, and vegetables.
• In the production of public health insecticides for mosquito control programs to combat vector-borne diseases such as malaria and dengue fever.
• For manufacturing professional pest control products targeting cockroaches, ants, and other urban pests in residential and commercial settings.
• In the creation of termiticides for soil pre-treatment and wood protection to prevent structural damage.
• As a technical material for developing insecticidal paints, coatings, or polymer-incorporated products for long-term release.
• For use in animal health ectoparasiticide formulations to control ticks, lice, and fleas in livestock.
• In stored product protection to safeguard grains and other commodities from insect infestation during storage.
