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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The combination according to claim 1, wherein the one or more additional herbicidal active ingredients is flufenacet. ### Claim 3 (depends on 1) The combination according to claim 1, wherein the one or more additional herbicidal active ingredients are flufenacet and diflufenican. ### Claim 4 (depends on 1) 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. ### Claim 5 (depends on 1) 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. ### Claim 6 (depends on 1) 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. ### Claim 7 (depends on 6) The method according to claim 6, wherein the combination is applied after emergence of the crop. ### Claim 8 (depends on 7) The method according to claim 7, wherein the agricultural crop is cereals, maize or rice. ### Claim 9 (depends on 7) 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. ### Claim 10 (depends on 7) 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. ### Claim 11 (depends on 2) 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. ### Claim 12 (depends on 11) The method according to claim 11, wherein the combination is applied after emergence of the crop. ### Claim 13 (depends on 12) The method according to claim 12, wherein the agricultural crop is cereals, maize or rice. ### Claim 14 (depends on 12) 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. ### Claim 15 (depends on 12) 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. ### Claim 16 (depends on 1) 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.
