Herbicide/safener combintions
View Patent ↗There are described herbicidal compositions which comprise at least one herbicidally active compound of the formula (I) and at least one crop-plant-protecting compound as safener. In this formula (I), V is an optionally substituted radical selected from the group consisting of isoxazol-4-yl, pyrazol-4-yl, cyclohexane-1,3-dion-2-yl and 3-oxopropionitril-2-yl and R 9 is nitro, amino, halogen or a carbon-containing radical. The group of the safeners contains, for example, 2,4-D, cyometrinil, dicamba, dymron, fenclorim, flurazole, fluxofenim, lactidichlor, MCPA, mecoprop, MG-191, oxabetrinil, methyl diphenylmethoxyacetate, 1-[4-(N-2-methoxybenzoylsulfamoyl)phenyl]-3-methylurea, 1,8-naphthalaic anhydride, 1-[4-(N-2-methoxybenzoylsulfamoyl)phenyl]-3,3-dimethylurea, 1-[4-(N-4,5-dimethylbenzoylsulfamoyl)phenyl]-3-methylurea, 1-[4-(N-naphthoylsulfamoyl)phenyl]-3,3-dimethylurea, (4-chlorophenoxy)acetic acid, 4-(2,4-dichlorophenoxy)butyric acid, 4-(4-chloro-o-tolyloxy)butyric acid, 4-(4-chlorophenoxy)butyric acid, in each case their acids and esters, N-acylsulfonamides, N-acylsulfamoylbenzamides, in each case, if appropriate, also in salt form and in each case optionally substituted 1-phenylpyrazoline, 1-phenylpyrazole, 1-phenyltriazole, 5-phenylisoxazoline and 5-phenylmethylisoxazoline-3-carboxylic esters and 2-(8-quinolinyloxy)acetic acid derivatives.
1. A herbicidally active composition comprising a mixture of:
A. a herbicidally active amount of a compound of the formula 3-2:

3. The herbicidally active composition as claimed in claim 1 , further comprising:
a further herbicide.
4. The herbicidally active composition as claimed in claim 2 , further comprising:
a further herbicide.
5. The herbicidally active composition as claimed in claim 3 ;
wherein the further herbicide is a sulfonylurea.
6. The herbicidally active composition as claimed in claim 4 ;
wherein the further herbicide is a sulfonylurea.
7. A method of controlling harmful plants in crops of useful plants, comprising:
applying a herbicidally active amount of a herbicidally active composition as claimed in one of claims 1 to 6 to the harmful plants, the crop plants, seeds of the crop plants, or an area on which the crop plants grow.
8. The method as claimed in claim 7 ;
wherein the crop plants belong to the group consisting of maize, wheat, rye, barley, oats, rice, sorghum, cotton, and soya.
9. The method as claimed in claim 7 ;
wherein the crop plants are genetically altered plants.
