  The present invention relates to piperazine compounds of the general formula I defined below and to their use as herbicides. Moreover, the invention relates to compositions for crop protection and to a method for controlling unwanted vegetation. In formula I, the variables have the following meanings: R 1 is selected from the group consisting of halogen, cyano, nitro, Z—C(═O)—R 11 , phenyl and a 5- or 6-membered heterocyclic radical which has 1, 2, 3 or 4 heteroatoms selected from the group consisting of O, N and S as ring atoms, where phenyl and the heterocyclic radical are unsubstituted or may have 1, 2, 3 or 4 substituents R 1a ; Z is a covalent bond or a CH 2 group; R 11 is hydrogen, C 1 -C 6 -alkyl, C 3 -C 6 -cycloalkyl, C 2 -C 6 -alkenyl, C 5 -C 6 -cycloalkenyl, C 2 -C 6 -alkynyl and the like; R 2 is hydrogen, halogen, nitro, cyano, C 1 -C 4 -alkyl, C 1 -C 4 -haloalkyl, C 2 -C 4 -alkenyl, C 1 -C 4 -alkoxy, C 1 -C 4 -haloalkoxy, benzyl or a group S(O) n R 21 in which R 21 is C 1 -C 4 -alkyl or C 1 -C 4 -haloalkyl and n is 0, 1 or 2; R 3 is hydrogen or halogen; R 4 is C 1 -C 4 -alkyl, C 3 -C 4 -alkenyl or C 3 -C 4 -alkynyl; R 5 is hydrogen, C 1 -C 4 -alkyl, C 3 -C 4 -alkenyl, C 3 -C 4 -alkynyl or a group C(═O)R 51 in which R 51 is hydrogen, C 1 -C 4 -alkyl, C 1 -C 4 -haloalkyl, C 1 -C 4 -alkoxy or C 1 -C 4 -haloalkoxy; R 6 is C 1 -C 4 -alkyl, C 1 -C 4 -hydroxyalkyl or C 1 -C 4 -haloalkyl; R 7 , R 8 independently of one another are hydrogen, OH, C 1 -C 4 -alkoxy, C 1 -C 4 -haloalkyloxy, C 1 -C 4 -alkyl or C 1 -C 4 -haloalkyl; and R 9 , R 10 independently of one another are selected from the group consisting of hydrogen, halogen, CN, NO 2 , C 1 -C 4 -alkyl, C 1 -C 4 -haloalkyl, C 2 -C 4 -alkenyl, C 1 -C 4 -alkoxy and C 1 -C 4 -haloalkoxy.
