Ethion (C9H22O4P2S4) is an organophosphate insecticide. It is known to affect the neural enzyme acetylcholinesterase and disrupt its function.
== History == Ethion was first registered in the US as an insecticide in the 1950s. Annual usage of ethion since then has varied depending on overall crop yields and weather conditions. For example, 1999 was a very dry year; since the drought reduced yields, the use of ethion was less economically rewarding. Since 1998, risk assessment studies have been conducted by (among others) the EPA (United States Environmental Protection Agency). Risk assessments for ethion were presented at a July 14, 1999 briefing with stakeholders in Florida, which was followed by an opportunity for public comment on risk management for this pesticide.
