The invention comprises amido-phosphazides of the general formula:-[(R)2N]3P=N-N=N-R1 wherein R is a C1-C4 alkyl radical or wherein (R)2N forms a piperidine, piperazine, morpholine, thiamorpholine or pyrrolidine ring system and R1 stands for a phenyl, C1-C4 alkylsubstituted phenyl, halo-substituted phenyl, nitro-substituted phenyl, chloro- and nitro-substituted phenyl, carbalkoxy-substituted phenyl, di C1-C4 alkylamino-substituted phenyl, C1-C4 alkoxy-substituted phenyl, naphthyl, benzoyl, halo-substituted benzoyl, C1-C4 alkylsubstituted benzoyl, nitro-substituted benzoyl, or carbalkoxy-substituted benzoyl. They may be obtained by reacting appropriate aromatic azides with appropriate phosphorous acid triamides, the reaction being carried out in the presence of an inert diluent, e.g. ether. On heating the products above their melting point decomposition occurs with the evolution of nitrogen, the corresponding imines being formed. The amido-phosphazide products have insecticidal properties (see Group VI).ALSO:A pesticidal composition comprises a solid or liquid carrier or diluent and an amido-phosphazide of the formula <FORM:0919868/VI/1> wherein R is a C1-C4 alkyl radical or wherein [(R)2N] forms a piperidine, piperazine, morpholine, thiamorpholine or pyrrolidine ring system, and R1 is a phenyl radical which may be unsubstituted or substituted by C1-C4 alkyl, halogen, nitro, chlorine and nitro, carbalk oxy, di C1-C4 alkyl-amino, or C1-C4 alkoxy group, naphthyl, or benzoyl, halo-benzoyl, C1-C4 alkyl benzoyl, nitro-benzoyl, or carbalkoxy-benzoyl (see Group IV (b)). Specified carriers or diluents are talc, chalk, bentonite, clay, water (if necessary with an emulsifier), alcohols, ketones, dimethyl formamide, and liquid hydrocarbons. The amido-phosphazides may be used in combination with each other or with known insecticides and/or fertilizers.
