The present invention relates to active compound concentrates having herbicidal action, comprising a) from 10 to 100 g/l of at least one 4-benzoyl-substituted pyrazole compound of the formula I in which R1, R3 independently of one another are hydrogen, halogen, methyl, halomethyl, methoxy, halomethoxy, methylthio, methylsulfinyl or methylsulfonyl; R2 is a 5-membered heterocyclic radical which is unsubstituted or carries 1, 2, 3 or 4 substituents selected from the group consisting of halogen, C1-C6-alkyl, C1-C4-alkoxy, C1-C4-haloalkyl, C1-C4-haloalkoxy and C1-C4-alkylthio; R4 is hydrogen, halogen or methyl; R5 is C1-C6-alkyl, C3-C6-cycloalkyl or C3-C6-cycloalkylmethyl; and R6 is hydrogen or C1-C4-alkyl; or one of its agriculturally useful salts, b) from 200 to 700 g/l of 2-chloro-N-(2,4-dimethyl-3-thienyl)-N-(2-methoxy-1-methylethyl)acetamide, and c) from 10 to 200 g/l of at least one surfactant S selected from a mixture of at least one anionic surfactant and at least one nonionic surfactant, where the components a), b) and c) are present dissolved in a mixture of organic solvents consisting to at least 95% by weight, based on the solvent mixture, of d1) at least one aprotic polar organic solvent having a miscibility with water at 25° C. and 1 bar of at least 50 g/l, and d2) at least one organic solvent having a solubility in water at 25° C. and 1 bar of less than 5 g/l.
