Parathion - Parachion (English spelling)

The international standard name for the chemical name O,O-diethyl-Op-nitrophenylthiophosphate. Invented in Germany in 1944, it was imported to Japan under the brand name Holidol, and used nationwide from 1952 (Showa 27) due to its outstanding effectiveness in controlling the rice stem borer and other insects. It was domestically produced by Sumitomo Chemical Co., Ltd. (now Sumitomo Chemical) in 1958, and many agrochemical companies purchased the raw material and sold it as a formulation. It was extremely useful in promoting agriculture (increasing food production), but due to the high incidence of poisonings, its use was banned in Japan in 1971.
