Abstract

Herbicidal sulphonylaminocarbonyltriazolinones having substituents bonded via oxygen of the formula ##STR1## in which R.sup.1 represents hydrogen, amino, or an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, aralkyl, aryl, alkylamino, cycloalklamino or dialkylamino radical, PA1 R.sup.2 represents an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aralkyl or aryl radical, and PA1 R.sup.3 represents an optionally substituted alkyl, aralkyl, aryl or heteroaryl radical, and salts thereof, with the exception of the compounds: PA0 2-(2-methoxycarbonyl-phenylsulphonylaminocarbonyl)- 4-methyl-5-methoxy-2,4-dihydro-3H-1,2,4-triazol-3-one, PA0 2-(2-trifluoromethoxy-phenylsulphonylaminocarbonyl)- 4-cyclopropyl-5-methoxy-2,4-dihydro-3H-1,2,4- triazol-3-one, PA0 2-(2-difluoromethoxy-phenylsulphonylaminocarbonyl)- 4-cyclobutyl-5-ethoxy-2,4-dihydro-3H-1,2,4-triazol-3-one, and PA0 2-(2-methoxycarbonyl-phenylsulphonylaminocarbonyl)- 4-ethyl 5-ethoxy-2,4-dihydro 3H-1,2,4-triazol-3-one
