Abstract
The invention discloses a herbicide composition containing diflufenican and pyroxasulfone. The herbicide composition adopts diflufenican and pyroxasulfone as active ingredients, wherein a mass ratio of diflufenican to pyroxasulfone is (1 to 10) to (10 to 1); and then the diflufenican and pyroxasulfone are mixed with pesticide allowable additives and/or aids to prepare a composition with a dosage form of suspension, emulsion oil, micro-emulsion, dispersible oil suspension, wettable powder or water dispersion. The diflufenican and pyroxasulfone in the herbicide composition synergistically play a pesticide effect with completely different action mechanisms, so that poaceae and broadleaf weeds can be effectively prevented and removed, the drug resistance generation speed of the weeds is greatly lowered, the weeding activity of the herbicide is improved, and the safety to crops is high. The application prospect is good.
