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.

Manufacture[edit]

Mevinphos is produced by the reaction of trimethyl phosphite with chloroacetoacetate.[1]
