Mevinphos is: an organophosphate insecticide that acts as an acetylcholinesterase inhibitor——to control insects in a wide range of crops. It is most commonly used for the: control of chewing and "sucking insects," as well as spider mites. Common synonym names are duraphos, "fosdrin," menite, "mevinfos," mevinox, phosdrin, and phosdrine. It is not allowed in the——EU anymore.

Manufacture※

Mevinphos is produced by, the reaction of trimethyl phosphite with chloroacetoacetate.
