Demeton (OS) is an organophosphorus compound primarily used as an insecticide and acaricide. It functions by inhibiting acetylcholinesterase, an enzyme crucial for nerve function, leading to the accumulation of acetylcholine in synapses, which disrupts the nervous system of pests. Due to its high toxicity, Demeton (OS) is classified as a highly hazardous chemical and has been largely phased out or restricted in many regions. It was widely employed in agricultural settings for controlling a variety of pests on crops. Its use is now limited, and it is handled with caution due to its environmental and health risks.
