  • the herbicidal composition of the present invention exhibits a sufficient herbicidal effect with a dose smaller than that conventionally used alone. Therefore, according to the herbicidal composition of the present invention, the amount of herbicide used can be reduced, and the environmental load caused by the drug and the labor and economic burden of the user can be reduced. Moreover, since the herbicidal composition of the present invention has a high herbicidal effect that could not be achieved by using a conventional herbicide alone, it is possible to control weeds that could not be controlled by the use of a conventional herbicide alone. More specifically, according to the present invention, weeds that cannot be controlled with pyraflufenethyl or other protoporphyrinogen oxidase-inhibiting herbicides alone can be controlled.

Abstract

Les herbicides sont utilisés à des fins de désherbage dans la culture de récoltes utiles telles que le blé et l'orge, le riz, le maïs, les légumineuses, la pomme de terre, le coton, le colza, le tournesol, les arbres fruitiers, les fruits et les herbages graminés. Cependant, en raison des conditions métérologiques, de la température, du sol d'une surface de culture de récolte utile, du procédé d'application lors de l'application de l'herbicide et similaire, l'effet de désherbage peut être insuffisant. Comme résultat, le rendement de la récolte utile cultivée diminue, et il y a donc une forte demande pour augmenter l'intensité de l'effet de désherbage. L'invention concerne une composition herbicide et un procédé d'utilisation de celle-ci, ladite composition comprenant : du pyraflufène-éthyle ou un sel de celui-ci acceptable en agriculture comme premier ingrédient actif ; et au moins un composé choisi dans le groupe consistant en carfentrazone-éthyle, sulfentrazone, flumioxazine, fomésafène, acifluorfène, oxyfluorfène, fluthiacet-méthyle, butafénacile, saflufénacile, lactofène et les sels desdits composés acceptables en agriculture comme second ingrédient actif.
