Abstract: 1. A herbicidal mixture comprising a) a herbicidally active amount of a 3-heterocyclyl-substituted benzoyl derivative of the formula I in which the substitutes have the following meanings: R<1> ,R<2> are hydrogen, halogen, C1-C6-alkyl, C1-C6-alkylthio, C1-C6-alkylsulfinyl, C1-C6-alkylsulfonyl, C1-C6-haloalkyl, C1-C6-alkoxy, C1-C6-haloalkoxy; R<3> is hydrogen, halogen, C1-C6-alkyl; X is a heterocycle from amongst the group consisting of isoxazolyl, 4,5-dihydroisoxazolyl and thiazolyl, it being possible for the heterocycle to be optionally monosubstituted or polysubstituted by halogen, C1-C6-alkyl, C1-C4-alkoxy, C1-C4-haloalkyl, C1-C4-haloalkoxy, C1-C4-alkylthio; R<4> is a pyrazole which is linked in the 4-position of the formula II R<5> is hydrogen or C1-C6-alkyl, R<6> is C1-C6-alkyl, or their environmentally compatible salts; b) a nitrogenous fertilizer in a synergistically effective amount and c) an adjuvant in a synergistically effective amount which is selected from vegetable oils, which can be partially or completely hydrogenated, modified vegetable oils, mineral oils, alcohol alkoxylates, alcohol ethoxylates, alkylated EO/PO block copolymers, alkylphenol ethoxylates, polyols, EO/PO block copolymers, organosilicon compounds, alkylglycosides, alkyl polyglycosides, alkyl sulfates, sulfated alcohol alkoxylates, alkylarylsulfonates, alkylsulfonates, dialkylsulfosuccinates, phosphated alcohol alkoxylates, fatty amine alkoxylates, esters, carboxylates, ester ethoxylates, dialkyl adipates, dicarboxylic acid derivatives, such as alkenylsuccinic anhydride condensates with polyalkylene oxides or polyhydroxyamines; dialkyl phthalates, ethoxylated sorbitan esters of natural fatty acids and ethoxylated glycerides of natural fatty acids. 2. A herbicidal mixture as claimed in claim 1, comprising a 3-heterocyclyl-substituted benzoyl derivative of the formula I as claimed in claim 1 where R<3> is hydrogen. 3. A herbicidal mixture as claimed in claim 1, comprising a 3-heterocyclyl-substituted benzoyl derivative of the formula I as claimed in claim 1, where R<1>,R<2> are halogen, C1-C6-alkyl, C1-C6-alkylthio, C1-C6-alkylsulfinyl, C1-C6-alkylsulfonyl. 4. A herbicidal mixture as claimed in claims 1-3, comprising a 3-heterocyclyl-substituted benzoyl derivative of the formula I as claimed in claim 1 where X is isoxazolyl and 4,5-dihydroisoxazolyl, each of which can optionally be substituted by C1-C6-alkyl. 5. A herbicidal mixture as claimed in claims 1-4, comprising a 3-heterocyclyl-substituited benzoyl derivative of the formula I as claimed in claim 1 where X is isoxazol-5-yl, 3-methylisoxazol-5-yl, 4,5-dihydroisoxazol-3-yl, 4,5-dihydro-5-methylisoxazol-3-yl, 4,5-dihydro-5-ethylisoxazol-3-yl, 4,5-dihydro-4,5-dimethylisoxazol-3-yl. 6. A herbicidal mixture as claimed in claim 1, comprising 4-[2-chloro-3-(4,5-dihydroisoxazol-3-yl)-4-methylsulfonylbenzoyl]-1-methyl-5-hydroxy-1H-pyrazole. 7. A herbicidal mixture as claimed in claim 1, comprising 4-[2-methyl-3-(4,5-dihydroisoxazol-3-yl)-4-methylsulfonylbenzoyl]-1-methyl-5-hydroxy-1H-pyrazole. 8. A herbicidal mixture as claimed in claims 1-7, comprising a nitrogenous fertilizer b) selected from the series consisting of ammonia, ammonium salts, urea, thiourea and mixtures of these. 9. A herbicidal mixture as claimed in claims 1-8, comprising 0.5-90% by weight of the 3-heterocyclyl-substituted benzoyl derivative a); 5-94.5% by weight of the nitrogenous fertilizer b); 5-50% by weight of the adjuvant c). 10. A process for the preparation of a herbicidal mixture as claimed in claim 1, which comprises mixing the components a) to c) of the herbicidal mixture with each other. 11. A method of controlling undesirable vegetation, which comprises mixing a herbicidally active amount of the components a) to c) of the herbicidal mixture as claimed in claims 1-9 with each other and allowing the mixture to act on the plants or their environment.
