-1- PH/5-189941A Selective herbicidal composition Abstract A selective herbicidal composition for controlling grasses and weeds in crops of useful plants is composed of a) a herbicidally effective amount of a sulfonylurea of the formula I Image (I), in which Q is a radical Image , Image or Image ; R0 is hydrogen, halogen, methyl or methoxy; Rl is halogen, Cl-C3haloalkyl, Cl-C3haloalkoxy, Cl- or C2alkoxy-C1-C3alkoxy, C3-C6alkenyloxy, C3-C6alkynyloxy, C2- or C3alkynyl, Image or a radical Image ; A and Z independently of one another are nitrogen or methine; D is nitrogen, methine or methylmethine; R2 is Cl-C3haloalkoxy, Cl- or C2alkoxy-C1-C3alkoxy, C4-C6cycloalkyloxy, C3-C6cycloalkyl-C1-C3alkoxy, -COOR4 or -NR5R6; R4 is C1-C3alkyl or 3-oxetanyl; R5 is -2- hydrogen or Cl-C4alkyl; R6 is hydrogen, C1-C4alkyl or -COR11; R11 is hydrogen orCl-C6alkyl; R3 is hydrogen or methyl; X is halogen, methyl, ethyl, methoxy, ethoxy, C1- or C2haloalkoxy, cyclopropyl, -NHCH3, or -N(CH3)2; Y is methyl, ethyl, methoxy, ethoxy, Cl- or C2-haloalkcoxy or cyclopropyl; and E is nitrogen or the methine group; and the agrochemically acceptable salts of these compounds, in which D and Z must not simultaneously be nitrogen; and F is the methine group if X is halogen or difluoromethoxy; and b), as safener, a herbicide-antagonistically effective amount of a 1,5-diphenylpyrazole-3-carboxylic acid derivative of the formula II Image (II), in which R7 is hydrogen, C1-C8alkyl, C3-C6alkenyl, C3-C6cycloalkyl-C1-C3alkyl, or an alkali metal or ammonium cation; and R8, R9 and R10 independently of one another are hydrogen or halogen.
