The invention relates to an aqueous active ingredient concentrate, comprising in dissolved form: a) at least one 4-benzoyl-substituted pyrazol compound of the formula (I), wherein R 1 , R 3 independently of each other stand for hydrogen, halogen, methyl, halogen methyl, methoxy, halogen methoxy, methylthio, methyl sulfinyl, or methyl sulfonyl; R 2 stands for a 5-membered heterocyclic residue, which is unsubstituted, or which carries 1, 2, 3, or 4 substituents, which are selected from halogen, C 1 -C 6 -alkyl, C 1 -C 4 -akoxy, C 1 -C 4 -halogenalkyl, C 1 -C 4 -halogen alkoxy, and C 1 -C 4 -alkylthio; R 4 stands for hydrogen, halogen, or methyl; R 5 stands for C 1 -C 6 -alkyl, C 3 -C 6 -cycloalkyl, or C 3 -C 6 -cycloalkyl methyl; and R 6 stands for hydrogen or C 1 -C 4 -Alkyl; or one of its salts used in agriculture; b) at least one benzoic acid compound of the formula (II), wherein R 7 stands for hydrogen, halogen, hydroxy, or methoxy, and R 8 stands for hydrogen, halogen, or amino; or one of its salts used in agriculture; and c) have at least one non-ionic surface-active substance S, selected from polyether compounds having repeat units derived from ethylene oxide, alkyl polyglycosides, and mixtures thereof.
