Monocrotophos is an organophosphate insecticide. It is acutely toxic to birds and humans, so it has been banned in the U.S., the E.U. and many other countries, however it is still available in India.
Monocrotophos is principally used in agriculture, as a relatively cheap pesticide. However, it is also used frequently as a tool to commit suicide.
