Abstract

The invention relates to novel heterocyclyltriazolinones of the general formula (I) ##STR1## in which R.sup.1 represents hydrogen or represents alkyl or cycloalkyl, each of which is optionally substituted, R.sup.2 represents hydrogen, hydroxyl, mercapto or halogen or represents alkyl, alkenyl, alkinyl, cycloalkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, arylalkyl, amino or heterocyclyl, each of which is optionally substituted, and Het represents an optionally substituted heterocycle of the formula ##STR2## in which X in each case represents oxygen, sulphur, an NH group or an N-alkyl group, a process for their preparation and their use as herbicides.
