1. A herbicidal composition comprisinga) at least one sulfonylurea of the formula I ##STR4## where the substituents have the following meanings:

  • R1 is C1 -C6 -alkyl which carries one to five of the following groups;

    methoxy, ethoxy, SO2 CH3, cyano, chlorine, fluorine, SCH3, S(O)CH3 ;

    halogen;

    a group ER6 where E is O, S or NR7 ;

    COOR8 ;

    NO2 ;

    S(O)R9 ;

    S(O)2 R9 ;

    SO2 NR10 R11 ;

    CONR10 R11 ;

    R2 is hydrogen, C1 -C4 -alkyl, C2 -C4 -alkenyl, C2 -C4 -alkynyl, halogen, C1 -C4 -alkoxy, C1 -C4 -haloalkoxy, C1 -C4 -haloalkyl, C1 -C2 -alkylsulfonyl, nitro, cyano or C1 -C4 -alkylthio;

    R3 is F, CF3, CF2 Cl, CF2 H, OCF3, OCF2 Cl, or, if R1 is CO2 CH3 and R2 is simultaneously fluorine, R3 is Cl, or, if R1 is CH2 CF3 or CF2 CF3, R3 is methyl, or, if R4 is OCF3 or OCF2 Cl, R3 is OCF2 H or OCF2 Br;

    R4 is C1 -C2 -alkoxy, C1 -C2 -alkyl, C1 -C2 -alkylthio, C1 -C2 -alky-lamino, di-C1 -C2 -alkylamino, halogen, C1 -C2 -haloalkyl, C1 -C2 -haloalkoxy;

    R5 is hydrogen, C1 -C2 -alkoxy, C1 -C4 -alkyl;

    R6 is C1 -C4 -alkyl, C2 -C4 -alkenyl, C2 -C4 -alkynyl or C3 -C6 -cy-cloalkyl, where these groups may carry 1 to 5 halogen atoms, with the exception of allyl, difluoromethoxy, chlorodifluoromethoxy and 2-chloroethoxy when E is O or S;

    or in the event that E is O or NR7, R6 is furthermore methylsulfonyl, ethylsulfonyl, trifluoromethylsulfonyl, allylsulfonyl, propargylsulfonyl or dimethylsulfamoyl;

    R7 is hydrogen, methyl or ethyl;

    R8 is C1 -C6 -alkyl, which may carry up to three of the following radicals;

    halogen, C1 -C4 -alkoxy, C1 -C4 -alkylthio, C1 -C4 -haloalkoxy, C1 -C4 -alkoxy-C1 -C4 -alkoxy, C3 -C7 -cycloalkyl and/or phenyl;

    C5 -C7 -cycloalkyl which may carry up to three C1 -C4 -alkyl groups;

    C3 -C6 -alkenyl or C3 -C6 -alkynyl;

    R9 is C1 -C6 -alkyl, which may carry up to three of the following radicals;

    halogen, C1 -C4 -alkoxy, C1 -C4 -alkylthio, C1 -C4 -haloalkoxy, C1 -C4 -alkoxy-C1 -C4 -alkoxy, C3 -C7 -cycloalkyl and/or phenyl;

    C5 -C7 -cycloalkyl which may carry up to three C1 -C4 -alkyl groups;

    C3 -C6 -alkenyl or C3 -C6 -alkynyl;

    R10 is hydrogen, C1 -C2 -alkoxy, C1 -C6 -alkyl, or together with R11 is a C4 -C6 -alkylene chain in which one methylene group may be replaced by an oxygen atom or a C1 -C4 -alkylimino group;

    R11 is C1 -C4 -alkyl which may carry one to four halogen or C1 -C4 -alkoxy radicals;

    C3 -C6 -cycloalkyl;

    n is 0-3;

    z is N or CH,or an enviromentally compatible salt of I, andb) an aryloxyalkanoic acid selected from the group consisting of 2,4-D, 2,4-DB, dichlorprop, dichlorprop-P (2,4-DP-P), fluoroxypyr, MCPA, mecoprop, mecoprop-P, and an enviromentally compatible salt thereof.
