Used as a broad-spectrum insecticide in agriculture to control a wide range of pests including aphids, bollworms, leafhoppers, and mites on crops such as cotton, vegetables, fruits, and cereals. It is effective in both field and greenhouse applications due to its fast knockdown effect and long residual activity. Commonly applied through foliar sprays, it penetrates insect nervous systems, causing paralysis and death. Also used in veterinary settings to control ectoparasites on livestock and in public health programs to manage disease-carrying insects like mosquitoes and ticks. Its isomeric purity enhances potency compared to technical-grade cypermethrin, allowing lower application rates and reduced environmental impact.
