The invention relates to a weed control composition containing pyriftalid, fenoxaprop-p-ethyl and metamifop. The active ingredients of the composition refer to the pyriftalid, the fenoxaprop-p-ethyl and the metamifop, and the weight part ratio of the pyriftalid to the fenoxaprop-p-ethyl to the metamifop is (1-20) to (1-5) to (1-15). The weed control composition disclosed by the invention has a synergetic effect and can be used for controlling annual weeds in paddy fields, the effect is obviously superior to that of single or binary mixture application of a single agent, the herbicide controlling spectrum is widened, the use amount of the pesticides is reduced, the environmental pollution is alleviated, and the drug resistance of weeds is delayed. |
