Used primarily as an organophosphate insecticide in agriculture to control a wide range of pests on crops such as corn, soybeans, fruits, and vegetables. It is effective against insects like aphids, mites, and borers by disrupting their nervous system. Also applied in non-agricultural settings including turf, ornamental plants, and sometimes in structural pest control. Has been used in mosquito control programs to reduce disease transmission. Due to health and environmental concerns, especially its neurotoxic effects on children and wildlife, many countries have restricted or banned its use in recent years.
