A herbicidal composition comprising (1) 1-(1-ethyl-4-(3-(2-methoxyethoxy)-2-methyl-4-(methylsulfonyl)benzoyl)-1H-pyrazol-5-yloxy)ethyl methyl carbonate or its salt and (2) at least one compound selected from the group consisting of fenchlorazole-ethyl, isoxadifen-ethyl, mefenpyr-diethyl, cloquintocet-mexyl and cyprosulfamide. ## Claims ### Claim 1 A herbicidal composition comprising component (1) 1-(1-ethyl-4-(3-(2-methoxyethoxy)-2-methyl-4-(methylsulfonyl)benzoyl)-1H-pyrazol-5-yloxy)ethyl methyl carbonate or its salt and component (2) at least one compound selected from the group consisting of fenchlorazole-ethyl, isoxadifen-ethyl, mefenpyr-diethyl, cloquintocet-mexyl and cyprosulfamide, which contains the component (1) and the component (2) in a weight ratio of from 1:0.05 to 1:2. ### Claim 2 (depends on 1) The herbicidal composition according to claim 1, which further contains (3) another herbicidal compound. ### Claim 3 (depends on 1) The herbicidal composition according to claim 1, which contains the component (1) and the component (2) in a weight ratio of from 1:0.1 to 1:1 for at least one cool season turfgrass selected from the group consisting of kentucky bluegrass, perennial ryegrass and bentgrass, for wheat, for corn or for timothy. ### Claim 4 (depends on 1) The herbicidal composition according to claim 1, which contains the component (1) and the component (2) in a weight ratio of from 1:0.1 to 1:1 for at least one cool season turfgrass selected from the group consisting of kentucky bluegrass, perennial ryegrass and bentgrass. ### Claim 5 (depends on 1) The herbicidal composition according to claim 1, which contains the component (1) and the component (2) in a weight ratio of from 1:0.1 to 1:1 for wheat or for corn. ### Claim 6 A method for controlling undesired plants, which comprises applying a herbicidally effective amount of component (1) 1-(1-ethyl-4-(3-(2-methoxyethoxy)-2-methyl-4-(methylsulfonyl)benzoyl)-1H-pyrazol-5-yloxy)ethyl methyl carbonate or its salt and an amount effective as a safener of component (2) at least one compound selected from the group consisting of fenchlorazole-ethyl, isoxadifen-ethyl, mefenpyr-diethyl, cloquintocet-mexyl and cyprosulfamide, to the undesired plants or to a place where they grow, wherein the component (1) is applied in an amount of from 5 to 150 g/ha and the component (2) is applied in an amount of from 0.25 to 300 g/ha to control the undesired plants. ### Claim 7 (depends on 6) The method according to claim 6, wherein a herbicidally effective amount of (3) another herbicidal compound is further applied. ### Claim 8 (depends on 6) The method according to claim 6, wherein the component (1) is applied in the amount of from 5 to 150 g/ha and the component (2) is applied in the amount of from 0.25 to 300 g/ha to control the undesired plants in cultivation or growth control of at least one cool season turfgrass selected from the group consisting of kentucky bluegrass, perennial ryegrass and bentgrass, of wheat, of corn or of timothy. ### Claim 9 A method for improving the safety of component (1) 1-(1-ethyl-4-(3-(2-methoxyethoxy)-2-methyl-4-(methylsulfonyl)benzoyl)-1H-pyrazol-5-yloxy)ethyl methyl carbonate or its salt for useful plants by component (2) at least one compound selected from the group consisting of fenchlorazole-ethyl, isoxadifen-ethyl, mefenpyr-diethyl, cloquintocet-mexyl and cyprosulfamide, comprising applying, to the useful plants and/or undesired plants or to a place where they grow, component (1) in an amount of from 5 to 150 g/ha, and component (2) in an amount of from 0.25 to 300 g/ha. ### Claim 10 (depends on 9) The method according to claim 9, wherein the component (1) is applied in the amount of from 5 to 150 g/ha and the component (2) is applied in the amount of from 0.25 to 300 g/ha to improve the safety for cool season turfgrasses selected from kentucky bluegrass, perennial ryegrass and bentgrass, for wheat, for corn or for timothy. ### Claim 11 A method for reducing an undesired effect of component (1) 1-(1-ethyl-4-(3-(2-methoxyethoxy)-2-methyl-4-(methylsulfonyl)benzoyl) -1H-pyrazol-5-yloxy)ethyl methyl carbonate or its salt against useful plants by component (2) at least one compound selected from the group consisting of fenchlorazole-ethyl, isoxadifen-ethyl, mefenpyr-diethyl, cloquintocet-mexyl and cyprosulfamide, comprising applying, to the useful plants and/or undesired plants or to a place where they grow, component (1) in an amount of from 5 to 150 g/ha, and component (2) in an amount of from 0.25 to 300 g/ha. ### Claim 12 (depends on 11) The method according to claim 11, wherein the component (1) is applied in the amount of from 5 to 150 g/ha and the component (2) is applied in the amount of from 0.25 to 300 g/ha to reduce an undesired effect against at least one cool season turfgrass selected from the group consisting of kentucky bluegrass, perennial ryegrass and bentgrass, against wheat, against corn or against timothy.
