The invention discloses a herbicide composition containing metamifop, cyhalofop-butyl, and bentazone, and the balance auxiliary ingredients which are allowed to use or are acceptable in pesiticides. The mass ratio of active ingredient metamifop, cyhalofop-butyl, and bentazone in the herbicide composition is 1-50:0.1-20:0.1-40, the total mass amount of the active ingredients accounts for 1 to 6% of the total mass amount of the herbicide composition. The herbicide composition can be made into missible oil, suspending agents, wettable powder, water dispersible granules, emulsion in water, microemulsions, granules, microcapsules, and aqueous solutions. The herbicide composition can be used for preventing and killing paddy field main weeds, such as barnyard grass, euphorbiae lathyridis, crab grass, eleusine indica, and winter wheat weeds, such as amur foxtail, oat grass, polypogon fugax, bluegrass, sclerochloa dura, puccinellia distans parl, Italian ryegrass, lolium temulentum, bromegrass, phleum paniculatum huds, aegilops tauschii, beckmannia syzigachne, wheatgrass, capsella bursa-pastoris, flixweed, and malachium aquaticum, effectively.
