The synthesis of phosphamidon, a new systemic insecticide, is describcd. By use of the 14C-labeled compound it is shown that in the bean plant phosphamidon undergoes rapid degradation, during which traces of the metabolites desethylphosphamidon,α-chloroacetoaceto-diethylamide, and α-chloroacetoaceto-ethylamide only are detectable. In order to explain the mechanism of the degradation reactions, the
