Herbicide composition containing saflufenacil

The invention discloses herbicide composition containing saflufenacil and an application of the herbicide composition. Effective active ingredients comprise first active ingredient saflufenacil, second active ingredient glyphosate and third active ingredient pyridine in the weight ratio being (0.1-50): (0.1-50): (0.1-50). The composition can be prepared in a form of agriculturally allowable water agents, suspending agents, suspending emulsions, dispersible oil suspending agents, wettable powder, water dispersible granules, granules and microcapsule suspension and suspension agents. The components are reasonable, the weeding effect is good, and the activity and the weeding effect of the herbicide composition are not simple superposition of activity of components; compared with existing single preparations or binary compound preparations, the herbicide composition not only has a remarkable weeding effect, but also has a remarkable synergic function, the dosage is reduced, the herbicide controlling spectrum is increased, and the composition has good safety for crops.
