Mevinphos

Mevinphos is a toxic organophosphate insecticide that acts as an acetylcholinesterase inhibitor to control insects in a wide range of crops. It was most commonly used for the control of chewing and sucking insects like aphids, grasshoppers, cutworms, leafhoppers, and caterpillars, as well as spider mites and ticks. Common synonym names are duraphos, fosdrin, menite, mevinfos, mevinox, phosdrin, and phosdrine. While there is no specific ban in the EU, it is not approved for use in any member nations. Nor is it approved for use in Canada. The EPA issued a Cancellation Order for all Mevinphos registrations on June 30, 1994, effectively banning its manufacture and use in the United States, all manufacture ceased shortly after, and its use was officially banned after February 28, 1995.

Manufacture

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