Weeding composite comprising oxaziclomefone

The invention discloses a weeding composite comprising oxaziclomefone and application of the weeding composite. The composite comprises a first active ingredient, namely the oxaziclomefone, a second active ingredient, namely pretilachlor or butachlor, and assistants. The weight ratio of the first active ingredient to the second active ingredient is (0.1-100): (10-150). The composite can be prepared into suspoemulsion, micro-capsule suspending agent, aqueous suspension agent, dispersible oil suspending agent, missible oil, microemulsion, emulsion in water, wettable powder, water dispersible granules and granules which are allowable agriculturally. The weeding composite is reasonable in composition, good in weeding effect and low in dosage cost, and activity and weeding effect of the composite are not simple superposition of component activity. Compared with existing single preparations, the weeding composite has the advantages of remarkable weeding effect and synergistic effect, high safety and conformity with safety requirements of pesticide preparations. The weeding composite is used for early-stage weeding of transplant fields and direct seedling fields and has high activity for weeds of paddy fields.
