Used primarily as a pesticide in agriculture, this chemical is effective against a wide range of insects including aphids, mites, and leafhoppers. It is commonly applied to crops such as cotton, tea, and vegetables to protect them from pest infestations. Due to its persistence in the environment and potential for bioaccumulation, its use is restricted or banned in many countries. It acts by disrupting the nervous system of insects, leading to paralysis and death. Often used in combination with other pesticides to enhance efficacy, it has also been employed in public health programs to control vector-borne diseases, though such applications are now limited.
