Ester and amide derivatives of N-(((alkoxy-(alkylthio)phosphinyl)amino)carbonyl)amino)alkanecarboxylic acids of the formula: ##STR1## (wherein R.sup.2 represents an alkyl group containing a carboxylic acid ester or amide moiety) were prepared by the reaction of O,S-dialkyl phosphoroisocyanatidothioates and ester and amide derivatives of naturally occurring and synthetic aminoacids and were found to be effective plant systemic and contact insecticides. Ethyl N-(((methoxy(methylthio)phosphinyl)amino)-carbonyl)methioninate, for example, were prepared from O,S-dimethyl phosphoroisocyanatidothioate and ethyl methioninate and found to control aster leafhoppers when applied to rice plants.
