Abstract
To provide a herbicidal composition which has a high herbicidal effect against undesired plants while stably maintaining the safety for useful plants, independently of various conditions such as weather conditions, soil conditions, varieties of the crop plants, and the timing for the application of the herbicide. 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.

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.
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.
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.
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.
