    Abstract: NEW MATERIAL:O-( 4-Bromo-2- chlorophenyl )0-methyl S-normalpropylphosphoro thioate shown by the formula I. USE:A fungicide, insecticide, acaricide, and nematocide. Having high controlling effects against various noxious insects, acarids, sanitary noxious insects, nematodes damaging agricultural and gardening crops, and blast of rice plant. Having excellent effects against Corposina niponensis, the improtant noxious insect of apple. Having no phytotoxicity. Having a wide insect-killing spectrum, the compound is capable of destroying noxious insects simultaneously in plants, e.g., vegetables, etc. so that it eliminates labor and is economical. PROCESS:An O-methyl S-normalpropylthiolphosphoric acid halide shown by the formula II (X is halogen) is reacted with 4-bromo 2-chlorophenol shown by the formula III in the presence of a base (dehydrohalogenating agent) in a solvent, e.g., henzene, at -5-100 deg.C for 1-6hr, to give a compound shown by the formula I in high yield.
