herbicidal composition comprising flazassulfuron and flumioxazin, or their salts and method for controlling unwanted plants or inhibiting their growth

摘要

many herbicidal compositions have been developed and are currently used. however, the weeds to be controlled are several in types and their emergence extends over a long period. thus, it is desired to develop a herbicidal composition that has a broad herbicidal spectrum, a high activity and a long-lasting effect. the present invention provides a herbicidal composition comprising (a) flazasulfuron, or its salt, and (b) at least one protoporphyrinogen oxidase inhibitor selected from the group consisting of a phenylpyrazole compound, a triazolinone compound, a compound of n -phenylphthalimide, a pyrimidindione compound, an oxadiazole compound, an oxazolidinedione compound, a thiadiazole compound, pyraclonil, profluazole, flufenpir-ethyl, and their salts. according to the present invention, a herbicidal composition that has a broad herbicidal spectrum, a high activity and a long-lasting effect can be provided.
