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 synergistic combination comprising 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidone (compound I) and one or more additional herbicidal active ingredients,
wherein the one or more additional herbicidal active ingredients is either flufenacet or flufenacet and diflufenican.

2. The combination according to claim 1 , wherein the one or more additional herbicidal active ingredients is flufenacet.

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

4. The combination according to claim 1 , wherein the 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.

5. The combination according to claim 1 , wherein the 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.

6. 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.

7. The method according to claim 6 , wherein the combination is applied after emergence of the crop.

8. The method according to claim 7 , wherein the agricultural crop is cereals, maize or rice.

9. The method according to claim 7 , wherein the one or more undesired plants are monocotyledonous or dicotyledonous annual weeds, or difficult-to-control perennial weeds.

10. The method according to claim 7 wherein the application rate of the compound I is 50 to 200 g of active ingredient (a.i.) per hectare, and wherein the application rate of the one or more herbicides is 5 to 500 g of active ingredient per hectare.

11. A method for controlling one or more undesired plants in an agricultural crop comprising applying the combination according to claim 2 to one or more plants and/or an area in which the plants grow.

12. The method according to claim 11 , wherein the combination is applied after emergence of the crop.

13. The method according to claim 12 , wherein the agricultural crop is cereals, maize or rice.

14. The method according to claim 12 , wherein the application rate of the compound I is 50 to 200 g of active ingredient (a.i.) per hectare, and wherein the application rate of the one or more herbicides is 5 to 500 g of active ingredient per hectare.

15. The method according to claim 12 , wherein the one or more undesired plants are monocotyledonous or dicotyledonous annual weeds, or difficult-to-control perennial weeds.

16. The combination according to claim 1 , 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.
