Used primarily as an organophosphate insecticide, effective against a range of pests in agricultural and non-agricultural settings. Commonly applied in crop protection to control sucking and chewing insects, especially in fruit and vegetable farming. Also utilized in public health programs for vector control, targeting mosquitoes and other disease-carrying insects. Its action as an acetylcholinesterase inhibitor makes it potent but also raises concerns about toxicity to non-target organisms, including humans and beneficial insects. Due to environmental and health risks, its use is restricted or banned in several countries.
