Laboratory Fumigation Tests of Organic Compounds

Abstract

A wide variety of organic compounds known to be insecticidal were screened as fumigants by a special laboratory procedure. Of the 78 compounds tested, five halogenated phosphorus Compounds—2-chlorovinyl dimethyl phosphate. 2.2-diehlorovinyl diethyl phosphate. DDVP, 1,2.2,2-tetrachloroethyl dimethyl phosphate, and Dow ET-57—and three halogenated hydrocarbons—aldrin, heptachlor. and lindane—caused complete knockdown of house flies (Musca domestica L.) in less than 2 hours.
