Abstract

O,O'-Dialkyl-O,O'-[2-aminopyrimidin(4,6)diyl]-bis-[(thiono)(thiol)phosphori c(phosphonic) acid esters] of the formula ##STR1## in which R is alkyl, PA1 R.sup.1 is alkyl, alkoxy or alkylthio, PA1 R.sup.2 and R.sup.3 each independently is alkyl or conjointly with the nitrogen atom form a heterocyclic ring which is optionally interrupted by at least one hetero-atom, PA1 R.sup.4 is hydrogen, alkyl or halogen, and PA1 X is oxygen or sulphur, Which possess arthropodicidal properties.
