Herbicidal sulphonylaminocarbonyltriazolinones having two substituents bonded via oxygen, of the formula ##STR1## in which R.sup.1 represents hydrogen or an optionally substituted radical from the series comprising alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl and aralkyl, R.sup.2 represents an optionally substituted radical from the series comprising alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl and aralkyl, and R.sup.3 represents an optionally substituted radical from the series comprising alkyl, aralkyl, aryl and heteroaryl, and their salts.

Intermediates for herbicides, the intermediates having the formula ##STR1## in which R is i-propyl, n-butyl, i-buty, s-butyl or cyclopropyl.

R.sup.2 represents an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aralkyl or aryl radical, and R.sup.3 represents an optionally substituted alkyl, aralkyl, aryl or heteroaryl radical, and salts thereof, with the exception of the compounds: 2-(2-methoxycarbonyl-phenylsulphonylaminocarbonyl)-4-methyl-5-methoxy-2,4-d ihydro-3H-1,2,4-triazol-3-one, 2-(2-trifluoromethoxy-phenylsulphonylaminocarbonyl)-4-cyclopropnl-5-methoxy -2,4-dihydro-3H-1,2,4-triazol-3-one, 2-(2-difluoromethoxy-phenylsulphonylaminocarbonyl)-cyclobutyl-5-ethoxy-2,4- dihydro-3H-1,2,4-triazol-3-one, and 2-(2-methoxycarbonyl-phenylsulphonylaminocarbonyl)-4-ethyl-5-ethoxy-2,4-dih ydro-3H-1,2,4-triazol-3-one.
