Pesticidally active pyrimidin-5-yl-(thio)phosphoric acid ester-amides

A pyrimidin-5-yl-(thio)phosphoric acid esteramide of the formula ##STR30## in which X is oxygen or sulphur,

• R is hydrogen, alkyl with 1 to 6 carbon atoms, aryl with 6 to 10 carbon atoms, or cycloalkyl with 3 to 6 carbon atoms,
• R.sup.1, R.sup.2, R.sup.4, R.sup.6 and R.sup.7 each independently is alkyl with 1 to 6 carbon atoms,
• R.sup.3 is alkyl, halogenoalkyl, cyanoalkyl, mono- or di-alkylamino with in each case 1 to 6 carbon atoms per alkyl part, an aryl radical which has 6 to 10 carbon atoms and is optionally substituted by at least one substituent independently selected from halogen, cyano, nitro, halogenoalkyl and halogenoalkoxy with 1 to 6 carbon atoms, and alkyl with 1 to 4 carbon atoms, or ##STR31## and R.sup.5 is alkyl with 1 to 6 carbon atoms, or an aryl which has 6 to 10 carbon atoms and optionally substituted by at least one substituent independently selected from halogen, cyano, nitro, halogenoalkyl and halogenoalkoxy with 1 to 6 carbon atoms and 1 to 5 halogen atoms, and alkyl with 1 to 4 carbon atoms.
