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.

Herbicidal composition having improved plant safety

In order to reduce the environmental load on an area where a herbicide is applied or a surrounding area thereof more than ever, it has been required to improve activity of a herbicidal active ingredient and to reduce its dose as far as possible. A herbicidal composition comprising (1) a benzoylpyrazole compound represented by the formula (I) or its salt: wherein each of Q, R, R, R, R, R, Rand A is as defined in the specification, and (2) at least one compound selected from the group consisting of a polyoxyalkylene sorbitan fatty acid ester, a polyoxyalkylene fatty acid ester, a polyoxyalkylene styryl aryl ether, a polyoxyalkylene styryl aryl ether condensate and a polyoxyalkylene alkyl ether sulfate.

Herbicidal composition having improved herbicidal activity

Many herbicidal compositions have been developed and used, but there are many types of weeds to be controlled, and their development lasts for a long period of time. Accordingly, it has been desired to develop a herbicidal composition having a wider herbicidal spectrum and having a highly active and long-lasting herbicidal activity. The present invention provides a herbicidal composition which comprises as active ingredients (a) at least one herbicidal compound selected from the group consisting of a benzoylpyrazole compound represented by the formula (I): (wherein each of R, R, R, Rand Ris alky, and Ris alkoxyalkoxy), sulcotrione and topramezone, and (b) amicarbazone.
