Abstract

The present invention is directed to new uses of the herbicidal active compound 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidone (compound I) as foliar herbicide. Furthermore, the present invention is directed to combinations comprising active compound 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidone (compound I) and to a method for controlling undesired weeds by applying the herbicidal active compound 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidone (compound I) or combinations comprising compound I to weeds or to the area in which the weeds grow after emergence of the crop.

First claim

The invention claimed is:

1. A combination comprising herbicidal active ingredient 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidone (compound I), one or more additional herbicidal active ingredients selected from the group consisting of aclonifen, flufenacet and diflufenican, and one or more safeners selected from the group consisting of isoxadifen-ethyl, cyprosulfamide, cloquintocet-mexyl and mefenpyr-diethylfurther,
wherein the 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidone (compound I) and the one or more additional herbicidal active ingredients are the only active compounds in the combination.

2. The combination according to claim 1 , wherein isoxadifen-ethyl is included as safener.

3. The combination according to claim 1 , wherein cyprosulfamide is included as safener.

4. The combination according to claim 1 , wherein cloquintocet-mexyl is included as safener.

5. The combination according to claim 1 , wherein mefenpyr-diethyl is included as safener.

6. The combination according to claim 1 , wherein the one or more additional herbicidal active ingredients are aclonifen and diflufenican.

7. The combination according to claim 1 , wherein the one or more additional active ingredients are flufenacet and diflufenican.

8. The combination according to claim 1 , wherein the one or more safener is mefenpyr-diethyl, and wherein the one or more additional active ingredients are aclonifen and diflufenican.

9. The combination according to claim 1 , wherein the one or more safener is mefenpyr-diethyl, and wherein the one or more additional active ingredients are flufenacet and diflufenican.

10. The combination according to claim 1 , wherein a weight ratio of the compound I to the one or more additional herbicidal active ingredients is in a range of from 1:40 to 50:1.

11. The combination according to claim 1 , wherein a weight ratio of the compound I to the one or more safeners is in a range of from 1:40 to 50:1.

12. The combination according to claim 1 , wherein a weight ratio of the compound I to the one or more additional herbicidal active ingredients is in a range of from 1:10 to 40:1.

13. The combination according to claim 1 , wherein a weight ratio of compound I to the one or more safeners is in a range of from 1:4 to 20:1.

14. A method for controlling one or more undesired plants in an agricultural crop comprising applying the combination according to claim 1 to one or more plants and/or an area in which the plants grow, after emergence of the plant.

15. The method according to claim 14 , for controlling the one or more undesired plants in one or more cereals, maize or rice crops.

16. The method according to claim 14 wherein an application rate of the compound I is 50 to 200 g of active ingredient (a. i.) per hectare, and wherein an application rate of the one or more safeners is 10 to 400 g of active ingredient per hectare.

17. The method according to claim 14 , wherein an application rate of the compound I is 50 to 200 g of active ingredient (a. i.) per hectare, an application rate of the one or more additional herbicidal active ingredients is 3 to 1500 g active ingredient per hectare, and an application rate of the one or more safeners is 10 to 400 g of active ingredient per hectare.
