Herbicidal substituted triazolinones of the formula <IMAGE> (I) in which R1 represents hydrogen, alkyl, alkenyl, alkynyl, halogenoalkyl, halogenoalkenyl, halogenoalkynyl, alkoxyalkyl, alkoxy, cycloalkylalkyl, cycloalkyl or in each case optionally substituted aralkyl or aryl, R2 represents alkyl, alkenyl, alkynyl, halogenoalkyl, halogenoalkenyl, halogenoalkynyl, alkoxyalkyl, alkoxy, cycloalkylalkyl, cycloalkyl or in each case optionally substituted aralkyl or aryl, R3 and R4 independently of one another each represent hydrogen, alkyl, alkenyl, alkynyl, halogenoalkyl, halogenoalkenyl, halogenoalkinyl, cyanoalkyl, hydroxyalkyl, alkoxyalkyl, alkoximinoalkyl, alkoxycarbonylalkyl, alkoxycarbonylalkenyl, alkylaminoalkyl, dialkylaminoalkyl, in each case optionally substituted cycloalkyl, cycloalkylalkyl, cyclcalkenyl or cycloalkenylalkyl, optionally substituted heterocyclylalkyl, in each case optionally substituted aralkyl, aroyl or aryl, alkoxy, alkenyloxy, alkynyloxy, aralkyloxy or aryloxy or, together with the nitrogen atom to which they are bonded, represent an optionally substituted heterocycle, X represents oxygen or sulphur and Y represents oxygen or sulphur, where X represents sulphur only, when at least one of the radicals R3 or R4 does not simultaneously represent hydrogen, methyl or ethyl.
