Phosphorous derivatives of carbamimidothioic-acid esters of the formula <CHEM> wherein R is an alkyl group containing 1 to 4 carbon atoms; R<1> is an alkyl group containing 1 to 4 carbon atoms, an alkoxy group containing 1 to 4 carbon atoms, al alkylthio group containing 1 to 4 carbon atoms, or an amino or mono-alkylamino group containing 1 to 4 carbon atoms; R<2> is an alkyl group containing 1 to 4 carbon atoms or an alkylthiolkyl group wherein each alkyl group independently contains from 1 to 4 carbon atoms; R<3> is an alkyl group containing 1 to 4 carbon atoms, a phenyl, substituted phenyl, benzyl or substituted benzyl group; R<4> is an alkyl group containing 1 to 4 carbon atoms, a benzyl or substituted benzyl group; or R<3> and R<4> when taken together represent an alkylene group containing 4 to 6 carbon atoms which group can be straight or branched chain or a group of one of the formulae &lsqbstr& CH2CH2 &rsqbstr& @ A or &lsqbstr& CH2CH(CH3) &rsqbstr& @ O wherein A is oxygen, sulfur or -NR; X is oxygen or sulfur, Y is oxygen, sulfur or -NH with the proviso that when Y is -@H, R can also be hydrogen; that when R<1> is alkoxy and Y is oxygen, X is also oxygen; that when R<1> is alkoxy and Y is sulfur, X is also sulfur and that when R<1> is alkylthio, X and Y are different; as well as their preparation and use as systemic insecticides and acaricides, as well as fungicides. |
