Uses Demeton-s-methyl is a pale yellow oil that has a sulfur-like odor. It is a systemic and contact insecticide and acaricide. It kills insects that feed on plants by sucking juices. It is used to control aphids, sawflies, and spider mites in fruits, vegetables, potatoes, cereals, ornamentals, and forestry. Demeton-s-methyl replaces methyl demeton, a mixture of demeton-s-methyl and demeton-o-methyl sold as systox meta. Demeton-s-methyl is more toxic to insects than demeton-o-methyl. It is available as an emulsifiable concentrate.28,40...

Systox ), was a mixture of two isomers 0-diethyl 0-ethylmercaptoethyl phosphorothioate (13.34a) and the corresponding thiolate (13.34b). The Bayer company eventually marketed these two components separately, as well as methyl-demeton in which both ethoxy groups had been replaced by methoxy groups. By then, the American systemic agent, dimethoate (13.35) was well established, and a Swiss analogue, phosphamidon (13.33) followed about 1960. These latter two enjoy the current FAO recommendation.
