Abstract

Herbicidally active guanidine derivatives of the formula ##STR1## in which m represents the numbers zero, 1 or 2, PA1 R.sup.5 represents an optionally substituted radical from the series comprising alkyl, aralkyl, aryl and heteroaryl, PA1 R.sup.2 represents a pyrimidin-2-yl radical which is substituted by halogen, amino, cyano or formyl and/or by optionally substituted radicals from the series comprising alkyl, alkoxy, alkylamino, dialkylamino, alkylcarbonyl and alkoxycarbonyl, PA1 R.sup.3 represents hydrogen, an optionally substituted radical from series comprising alkyl, cycloalkyl, alkenyl, alkinyl and aralkyl, PA1 R.sup.9 represents hydrogen or optionally substituted alkyl and PA1 R.sup.10 represents an optionally substituted radical from the series comprising alkyl, alkenyl, alkinyl, cycloalkyl, aralkyl, aryl, heteroaryl, alkyl- or alkoxycarbonyl and alkyl- or arylsulphonyl, or R.sup.9 and R.sup.10 together represent alkanediyl which is optionally interrupted by an oxygen atom; and PA1 M represents hydrogen, one equivalent of a metal, or an ammonium radical which is optionally substituted by alkyl, alkenyl, alkinyl and/or aralkyl, or--in the case in which M is bonded to the sa…
