The invention relates to novel substituted aryl sulphonyl amino(thio)carbonyl-triazolin(thi)ones of the formula (I) in which: Q1 is oxygen or sulphur; Q2 is oxygen or sulphur; R1 is hydrogen, amino or possibly substituted alkyl, alkoxy, alkyl carbonyl, alkoxy carbonyl, alkyl thio, alkyl sulphinyl, alkyl sulphonyl, alkenyl, alkinyl or alkylidene amino; R2 is hydrogen or possibly substituted alkyl, alkyl carbonyl, alkoxy carbonyl, alkyl sulphonyl, alkenyl or alkinyl or, together with R1, for alkane diyl possibly interrupted by oxygen and/or substituted alkandiyl; R3 is hydrogen, cyano, nitro, halogen or possibly substituted alkyl, alkyl carbonyl or alkoxycarbonyl; R4 is hydrogen, hydroxy, amino, alkylidene amino or a possibly substituted radical from the series alkyl, alkenyl, alkinyl, alkoxy, alkene oxy, alkyl amino, dialkyl amino, cycloalkyl, cycloalkyl alkyl, cycloalkyl amino, aryl, aryl alkyl; and R5 is hydrogen, hydroxy, mercapto, amino, cyano, halogen or a possibly substituted radical from the series alkyl, alkoxy, alkyl thio, alkyl amino, dialkyl amino, alkenyl, alkinyl, alkenyloxy, alkinyloxy, alkenyl thio, alkinylthio, alkenyl amino, alkinyl amino, cycloalkyl, cycloalkyloxy, cycloalkyl thio, cycloalkyl amino, cycloalkyl alkyl, aryl, aryloxy, aryl thio, aryl amino, aryl alkyl; and salts of compounds of formula (I), process for producing the novel compounds and their use as herbicides.
