The invention relates to novel 1-(2- oxyaminosulphonylphenylsulphonyl)-3-triazinylureas of the formula (I) <IMAGE> in which R<1> represents an optionally substituted radical from the series comprising alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, aralkyl and aryl, R<2> represents hydrogen, fluorine, chlorine, bromine, hydroxyl, cyclopropyl, C1-C4-alkyl [which is optionally substituted by fluorine and/or chlorine], C1-C4-alkoxy [which is optionally substituted by fluorine and/or chlorine], C1-C4-alkylthio [which is optionally substituted by fluorine and/or chlorine], amino, C1-C4-alkyl- or di-(C1-C4-alkyl)-amino [which are optionally substituted by fluorine] and R<3> represents hydrogen, fluorine, chlorine, bromine, hydroxyl, cyclopropyl, C1-C4-alkyl [which is optionally substituted by fluorine and/or chlorine], C1-C4-alkoxy [which is optionally substituted by fluorine and/or chlorine], C1-C4-alkylthio [which is optionally substituted by fluorine and/or chlorine], amino, or C1-C4-alkyl- or di-(C1-C4-alkyl)-amino [which are optionally substituted by fluorine], their preparation, and their use as herbicides.u |
