Use

Pirimicarb is used as an active ingredient in pesticides. It is used as a selective aphicide ( insecticide against aphids tube ) with a large number of cereals and other crops and acts by inhibiting acetylcholinesterase. It was first approved in 1970. With pirimicarb - desmethyl (CAS :30614 -22 -3) and pirimicarb - desmethyl- formamido ( 27218-04-8 ) are two derivatives with similar characteristics.
