Compositions and methods of killing insects and acarids using alkoxyimino carbamoyloxy phosphorus compounds

An insecticidal or acaricidal composition comprising an inert carrier and, as an essential active ingredient, in a quantity toxic to insects or acarids, a compound of the formula ##EQU16## wherein R.sup.1 is lower alkyl;

• R.sup.2 is selected from the group consisting of hydrogen, lower alkyl, lower alkenyl and lower haloalkyl;
• R.sup.3 is selected from the group consisting of hydrogen, lower alkyl, lower alkenyl, lower haloalkyl, cycloalkyl of from 3 to 7 carbon atoms and ##EQU17## wherein D is selected from the group consisting of lower alkyl, lower alkenyl, lower alkoxy, lower alkylthio, chlorine, bromine, fluoring, lower haloalkyl, nitro and di(lower alkyl)amino;
• u is an integer from 0 to 3;
• X.sup.1, X.sup.2, X.sup.3 and X.sup.4 are independently selected from the group consisting of oxygen and sulfur;
• m and n are each integers from 0 to 1;
• Z.sup.1 is selected from the group consisting of lower alkyl, lower alkenyl and ##EQU18## wherein A is selected from the group consisting of lower alkyl, lower alkenyl, lower alkoxy, lower alkylthio, lower haloalkyl, chlorine, bromine, fluoring, nitro, lower alkylsulfoxide, lower alkylsulfone and di(lower alkyl)amino;
• and q and p are each integers from 0 to 3;
• Z.sup.2 is selected from the group consisting of hydrogen and Z.sup.1, provided that when Z.sup.2 is hydrogen then n is zero;
• and Y is selected from the group consisting of lower alkyl, lower alkenyl, lower alkoxy, lower alkenyloxy, lower alkylthio, amino, lower alkylamino, di(lower alkyl)amino and ##EQU19## wherein E is selected from the group consisting of lower alkyl, lower alkenyl, lower alkoxy, lower alkylthio, chlorine, bromine fluorine, nitro, lower alkylsulfoxide, lower alkylsulfone and di(lower alkyl)amino;
• f is an integer from 0 to 3;
