Abstract: 1. A substantially water-free formulation of crop protection agents, comprising essentially a) a cyclohexenone oxime ether of the formula I where the variables are defined as follows: R<1> is ethyl or propyl; R<2> is hydrogen or an equivalent of an agriculturally useful cation; R<3> is 2-(thioethyl)propyl, tetrahydrothiopyran-3-yl, tetrahydrothiopyran-4-yl, tetrahydropyran-3-yl, tetrahydropyran-4-yl, 1-(methylthio)cyclopropyl, 5-(isopropyl)isoxazol-3-yl, 2,5-dimethylpyrazol-3-yl, 2,4,6-trimethylphenyl or 2,4,6-trimethyl-3-butyrylphenyl; R<4> and R<5> independently of one another are each hydrogen, methyl or methoxycarbonyl; Alk is CH2CH2, CH2CH(CH3), CH2 CH=CH, CH2CH=C(Cl) or CH2CH2CH=CH; R<6> is hydrogen, phenyl, halophenyl, dihalophenyl, phenoxy, halophenoxy or dihalophenoxy; b) N-phosphonomethylglycine, an ester or salt thereof, DL-homoalanin-4-yl(methyl)phosphinic acid or its ammonium salt; c) from 20 to 80 % by weight of an aprotic or weakly erotic solvent in which the components a) and b) are suspended; d) if desired emulsifiers, surfactants, surface-active and/or activity-enhancing auxiliaries. 2. A substantially water-free formulation of claim 1, comprising as component a) a cyclohexenone oxime ether selected from the group consisting of: sethoxydim, cycloxydim, clethodim, tralkoxydim, butroxydirn, 2-[1-(3-chloroallyloxy)iminopropyl]-5-(tetrahydropyran-4-yl)-3-hydroxycyclohex-2-enone, 2-(1-(2-p-chlorophenoxypropyloxy) iminobutyl)-5-(tetrahydro-thiopyran-3-yl)-3-hydroxycyclohex-2-enone, their alkali metal or alkaline earth metal salts or mixtures of these active ingredients. 3. A substantially water-free formulation of claim 1, comprising as component b) a mono-, di- or trideprotonated salt of glyphosate. 4. A substantially water-free formulation of either claim 1 or 2, comprising additionally from 0 to 80 % by weight of at least one formulation auxiliary selected from the classes of the surface-active ionic or nonionic surfactants, dispersants, other solvents and thickeners. 5. A substantially water-free formulation of claim 1, comprising additionally from 0 to 60 % by weight of a third herbicidally active compound selected from the group consisting of the aryloxyphenoxypropionic acids and their esters. 6. A process for preparing a spray liquor for controlling undesirable plants, which comprises mixing a formulation of claim 1 with ammonium salts, water and, if desired, other tankmix adjuvants. 7. A 2-[1-(3-chloroallyloxy)iminopropyl]-5-(tetrahydropyran-4-yl)-3-hydroxycyclohex-2-enone lithium salt. 8. An oil suspension concentrate comprises essentially a) at least one cyclohexenone oxime ether salt of the formula I where the variables are defined as follows: R<1> is ethyl or propyl; R<2> is hydrogen or an equivalent of an agriculturally useful cation; R<3> is 2-(thioethyl)propyl, tetrahydrothiopyran-3-yl, tetrahydrothiopyran-4-yl, tetrahydropyran-3-yl, tetrahydropyran-4-yl, 1-(methylthio)cyclopropyl, 5-(isopropyl)isoxazol-3-yl, 2,5-dimethylpyrazol-3-yl, 2,4,6-trimethylphenyl or 2,4,6-trimethyl-3-butyrylphenyl; R<4> and R<5> independently of one another are each hydrogen, methyl or methoxycarbonyl; Alk is CH2CH2, CH2CH(CH3), CH2 CH=CH, CH2CH=C(Cl) or CH2CH2CH=CH; R<6> is hydrogen, phenyl, halophenyl, dihalophenyl, phenoxy, halophenoxy or dihalophenoxy; b) from 20 to 80 % by weight of an aprotic or weakly erotic solvent in which the components a) are suspended; c) if desired emulsifiers, surfactants, surface-active and/or activity-enhancing auxiliaries. 9. The oil suspension concentrate of claim 8, comprising as component a) at least one cyclohexenone oxime ether salt of the formula I, where R<2> is an equivalent of alkali metal or alkaline earth metal cations. 10. The oil suspension concentrate of claim 9, where cyclohexenone oxime ether salt in an oil phase is presented as a solvent in an amount less than 1%.
