1. A herbicidal mixture, comprising a) a herbicidally effective amount of a 3-heterocyclyl-substituted benzoyl derivative of the formula I where: 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 the group consisting of isoxazolyl, 4,5-dihydroisoxazolyl and thiazolyl, where the heterocycle may be unsubstituted or mono- or polysubstituted by halogen, C1-C6-alkyl, C1-C4-alkoxy, C1-C4-haloalkyl, C1-C4-haloalkoxy, C1-C4-alkylthio; R<4> is a pyrazole of the formula II which is attached in the 4-position and where R<5> is hydrogen or C1-C6-alkyl, R<6> is C1-C6-alkyl, or their environmentally compatible salts; b) an adjuvant comprising i) a C1-C5-alkyl C5-C22-alkanoate, ii) a C10-C20-carboxylic acid, iii) a partial phosphoric ester or a partial sulfuric ester of a monohydroxy-functional polyalkyl ether and iv) if appropriate an alkyl polyoxyalkylene polyether in a synergistically effective amount. 2. A herbicidal mixture as claimed in claim 1, comprising a 3-heterocyclyl-substituted benzoyl derivative of the formula I as set forth in claim 1 where R3 is hydrogen. 3. A herbicidal mixture as claimed in claim 1 or 2, comprising a 3-heterocyclyl-substituted benzoyl derivative of the formula I as set forth in claim 1 wherein 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 any of claims 1 to 3, comprising a 3-heterocyclyl-substituted benzoyl derivative of the formula I as set forth in claim 1 where X is isoxazolyl or 4,5-dihydroisoxazolyl which may be unsubstituted or substituted by C1-C6-alkyl. 5. A herbicidal mixture as claimed in any of claims 1 to 4, comprising a 3-heterocyclyl-substituted benzoyl derivative of the formula I as set forth 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-methylsulfonyl-benzoyl]-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-methylsulfonyl-benzoyl]-1-methyl-5-hydroxy-1H-pyrazole. 8. A herbicidal mixture as claimed in any of claims 1 to 7, comprising 0.5 - 90% by weight of the 3-heterocyclyl-substituted benzoyl derivative a) and 10- 99.5% by weight of the adjuvant b). 9. A process for preparing a herbicidal mixture as claimed in any of claims 1 to 8, which comprises mixing the components a) and b) of the herbicidal mixture. 10. A method for controlling undesirable vegetation, which comprises allowing a herbicidally effective amount of the components a) and b) of the herbicidal mixture as claimed in any of claims 1 to 8 to act separately or jointly on the plants or their habitat. 11. A method for controlling undesirable vegetation, which comprises mixing a herbicidally effective amount of the components a) and b) of the herbicidal mixture as claimed in any of claims 1 to 8 and allowing it to act on the plants or their habitat.
