Herbicidal sulphonylaminocarbonyltriazolinones of the formula STR1 in which R1 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, R2 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 R3 represents an optionally substituted radical from the series comprising alkyl, aralkyl, aryl and heteroaryl, and salts thereof. Intermediates of the formula STR2 in which A1 represents in each case optionally substituted alkyl, alkenyl, cycloalkyl, alkoxy or dialkylamino and A2 represents hydrogen, or represents in each case optionally substituted alkyl, cycloalkyl, aralkyl, aryl or alkoxy, provided that both A1 and A2 do not simultaneously represent alkyl, are also new.
