Abstract: The object of the present invention is to find out a component which improves effects of agriculturally active ingredients, which is effective to contribute to reduction of the environmental load even in a small amount, in addition to bringing benefits to the health and/or growth of useful plants, by maximizing the effects of nicosulfuron, reducing phytotoxicity which is an undesired effect on the useful plants, etc. When nicosulfuron and isoxadifen-ethyl are used in combination, by adding a specific surfactant, benefits can be brought to the health and/or growth of useful plants even if the addition amount is remarkably smaller than the amount of the conventional adjuvant used.

Abstract: At present, 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, high activity and residual activity and thereby capable of controlling undesired plants for a long period of time. The present invention provides a herbicidal composition comprising as active ingredients (a) tolpyralate and (b) pyroxsulam.
