Use of sulfonylureas

A method of using one or more compounds of the formula (I) or salts thereof for the non-selective control of unwanted vegetation or for the selective control of unwanted vegetation in leguminous plants

• in which
• A is a CR11 grouping, where
• R11 is hydrogen,
• R1 is hydrogen or an optionally substituted radical from the group consisting of alkyl, alkoxy, alkoxyalkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, aralkyl and aryl,
• R2 is hydrogen, halogen or is in each case optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylamino or dialkylamino having in each case 1 to 6 carbon atoms,
• R3 is hydrogen, halogen or is in each case optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylamino or dialkylamino having in each case 1 to 6 carbon atoms,
• R4-R7 independently of one another are hydrogen, halogen, cyano, thiocyanato or are in each case optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, alkylcarbonyl, alkoxycarbonyl, alkylaminocarbonyl having in each case 1 to 3 carbon atoms, and
• R8 is hydrogen, halogen, cyano, thiocyanato or in each optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, alkylcarbonyl, alkoxycarbonyl, alkylaminocarbonyl having in each case 1 to 3 carbon atoms,
• where in the radicals mentioned above the alkyl and alkylene groups may each contain 1 to 6 carbon atoms, the alkenyl and alkynyl groups may each contain 2 to 6 carbon atoms, the cycloalkyl groups may each contain 3 to 6 carbon atoms and the aryl groups may each contain 6 or 10 carbon atoms, said method comprising the step of applying said one or more compounds of formula (I) or salts thereof to the unwanted vegetation or to seeds of the unwanted vegetation or to an area in which the unwanted vegetation grows.
