== Discovery == Diflufenican was discovered with a common intermediate method (CIM), and trialled in England and France between 1981 and 1983. A simple intermediate is reacted and recombined. Diflufenican derives from 2-chloronicotinic acid, one product replaced the chlorine with a phenoxy group, one receives an aniline group, and then both are recombined into DFF.
