Abstract

Herbicidal sulphonylaminocarbonyltriazolinones of the formula ##STR1## in which R.sup.1 represents hydrogen, hydroxyl or amino, or represents an optionally substituted radical from the series comprising alkyl, alkenyl, alkinyl, cycloalkyl, aralkyl, aryl, alkoxy, alkenyloxy, alkylamino and dialkylamino, PA1 R.sup.2 represents hydrogen, hydroxyl, mercapto or amino, or represents an optionally substituted radical from the series comprising alkyl, cycloalkyl, cycloalkenyl, aralkyl, aryl, alkoxy, alkylamino and dialkylamino, and PA1 R.sup.3 represents an optionally substituted radical from the series comprising alkyl, aralkyl, aryl and heteroaryl, and salts thereof. Intermediates of the formula ##STR2## in which A.sup.1 represents in each case optionally substituted alkyl, alkenyl, cycloalkyl, alkoxy or dialkylamino and PA1 A.sup.2 represents hydrogen, or represents in each case optionally substituted alkyl, cycloalkyl, aralkyl, aryl or alkoxy, provided that both A.sup.1 and A.sup.2 do not simultaneously represent alkyl, are also new.
