n is an integer selected from 1 or 2;
Y is phenyl or phenyl substituted by halogen, C 1 -C 6 alkyl or C 1 -C 6 haloalkyl, or
Y is diazole in which the diazole can be substituted by hydroxyl, halogen, C 1 -C 10 alkyl or C 1 -C 10 alkyl substituted by hydroxyl, C 1 -C 10 alkoxy, C 1 -C 4 haloalkyl, C 1 -C 4 haloalkoxy;
and
b) a herbicide-antagonistically active amount of a safener selected from the group consisting of cloquintocet-mexyl or a lithium, sodium, potassium, calcium, magnesium, aluminium, iron, ammonium, quaternary ammonium, sulfonium or phosphonium salt thereof, fenchlorazole-ethyl, mefenpyr-diethyl, isoxadifen-ethyl, furilazole or the R isomer thereof, benoxacor, dichlormid, MON4660, oxabetrinil, cyometrinil, the Z isomer thereof, fenclorim, N-cyclopropyl-4-(2-methoxy-benzoylsulfamoyl)-benzamide, N-isopropyl-4-(2-methoxy-benzoylsulfamoyl)-benzamide, naphthalic acid anhydride or flurazole, or a combination thereof.
2. The composition according to claim 1 , comprises the compound of the formula I where
R 1 and R 2 are each independently of the other C 1 -C 10 alkyl.
3. The composition according to claim 2 , comprises the compound of the formula I where
R 3 and R 4 are each independently of the other hydrogen or C 1 -C 10 alkyl.
4. The composition according to claim 3 , comprises the compound of the formula I where
R 5 and R 6 are hydrogen.
5. The composition according to claim 4 , comprises the compound of the formula I where
n is 1.
6. The composition according to claim 1 , comprises the compound of the formula I where
Y is phenyl or phenyl substituted by halogen.
7. The composition according to claim 1 , comprises the compound of the formula I where
Y is diazole or a diazole substituted by C 1 -C 10 alkyl, C 1 -C 4 haloalkyl, or C 1 -C 4 haloalkoxy.
8. The composition according to claim 1 , where in the compound of the formula I Y is pyrazol-4-yl or pyrazol-5-yl.
9. The composition according to claim 1 , wherein the compound of the formula I is 3-(5-difluoromethoxy-1-methyl-3-trifluoromethyl-1H-pyrazol-4-ylmethylsulfonyl)-5,5-dimethyl-4,5-dihydroisoxazole.
10. A method of combating weeds and weed grasses in crops of useful plants, wherein the useful plants, seed or cuttings thereof or a growing area thereof are treated simultaneously or at separate times with a herbicidally active amount of the herbicide of the formula I as defined in claim 1 and a herbicide-antagonistically active amount of the safener as defined in claim 1 .
11. The method according to claim 10 , wherein the crops of useful plants are maize.
12. The composition according to claim 9 , wherein the safener is selected from the group consisting of cloquintocet-mexyl or a lithium, sodium, potassium, calcium, magnesium, aluminium, iron, ammonium, quaternary ammonium, sulfonium or phosphonium salt thereof, fenchlorazole-ethyl, mefenpyr-diethyl, benoxacor or MON4660.
