Used primarily as a pesticide in agriculture, this chemical is effective against a wide range of insects including aphids, mites, and leafhoppers on crops such as cotton, tea, and vegetables. It acts as a contact and stomach poison, disrupting the nervous system of pests. Due to its persistence in the environment and potential for bioaccumulation, its use has been restricted or banned in many countries. It has also been found to contaminate soil and water systems, raising environmental and health concerns. In some regions, it is still applied in controlled settings for specific crop protection, though safer alternatives are increasingly preferred.
