Parathion

Parathion, also called parathion-ethyl or diethyl parathion and locally known as "Folidol", is an organophosphate compound. It is a potent insecticide and acaricide. It was originally developed by IG Farben in the 1940s. It is highly toxic to non-target organisms, including humans. Its use is banned or restricted in many countries, and there are proposals to ban it from all use.
