Cyanophos is a cholinesterase inhibitor[2] used as an insecticide and avicide; for example, against rice stem borers and house flies.[3] It is part of the chemical class of organophosphorus compounds, and is a yellow to reddish-yellow transparent liquid.

Safety[edit]

Cyanophos can enter the body via inhalation, ingestion, and contact with the skin and eyes. Symptoms of cyanophos poisoning resemble those of the chemical weapon sarin and include dyspnea, vomiting, diarrhea, abdominal pain, bronchorrhea, blurred vision, and opsoclonus.[1]

It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.[4]
