| 应用领域 | Uses: Used as an insecticide and acaricide to control aphids、red spider mites、whiteflies、leaf hoppers、and sawflies on vegetables、fruits、and hops、[ACGIH]、No longer registered for use in the USA、Farming (Pesticides) [Category: Industry]、For Demeton-S-methyl there are 0 labels match.、SRP: Not registered for current use in the U.S.、but approved pesticide uses may change periodically and so federal、state and local authorities must be consulted for currently approved uses.、Controls aphid vectors of virus diseases、white-flies、leafhoppers、and sawflies.、Systemic and contact insecticide and acaracide used to control aphids、and sawflies on garden crops、and hops.、Methods of Manufacturing: Demeton-S-methyl is made by the reaction of beta-hydroxyethyl sulfide (made in turn from ethyl mercaptan and ethylene oxide). It is reacted with O、O-dimethyl hydrogen phosphorothioate to give demeton-S-methyl.、Alkylation of O、O-dimethyl-thiophosphoric acid with 2-(ethylmercapto)-ethyl chloride.、2-ethylthioethanol + O、O-dimethyl phosphorochlorothioate (alcohol chlorination、hydrolysis、dehydrochlorination)、Formulations、Preparations: Demetox、DSM、Duratox、Metasystox 55、Mifatox、EC (580 ai、l)、Systemic Insecticide、EC (500 g、Emulsifiable concentrates、Phosphorothioic acid O-(2-(ethylthio)ethyl) O、O-dimethyl ester mixt with S-(2-(ethylthio)-ethyl) O、O-dimethyl phosphorothioate、Methyl demeton、Demeton-methyl、Methyl-mercaptophos、Methyl systox、Bayer 21、116、Metasystox、For more Formulations、Preparations (Complete) data for DEMETON-S-METHYL (7 total)、please visit the HSDB record page.、General Manufacturing Information: Phosphorothioic acid、S-[2-(ethylthio)ethyl] O、O-dimethyl ester: ACTIVE、The WHO Recommended Classification of Pesticides by Hazard identifies Demeton-S-methyl (technical grade) as Class IB: highly hazardous、Main Use: insecticide.、When introduced in 1954、technical grade methyl demeton was a 70:30 mixture of 0、0-dimethyl-0-ethylthioethyl phosphorothioate (demeton-0-methyl or 0-isomer) and 0、0-dimethyl-S-ethylthioethyl phosphorothioate (demeton-S-methyl or the S-isomer). The purified S-isomer was first marketed in 1957 and later replaced the mixture because it is more toxic to insects than the 0-isomer.、Not registered for use in、United States、.、Compatible with many other pesticides、but incompatible with alkaline materials.、For more General Manufacturing Information (Complete) data for DEMETON-S-METHYL (7 total) |
