The invention discloses a metaflumizone-containing pesticidal composition. The composition is mainly characterized by containing an active component A, an active component B and the balance of assistant, wherein the active component A is metaflumizone, and the active component B is lufenuron or pymetrozine; the weight ratio of the active component A to the active component B is 1:80-80:1; and the composition can be prepared into wettable powder, water-dispersible granules, a suspending agent, a suspended emulsion, an aqueous emulsion, a microemulsion, a microcapsule suspending agent and a microcapsule suspending-suspending agent. The composition disclosed by the invention can prevent and treat many ests, has an obvious synergistic action, widens the pesticidal spectrum, and has higher activity for pests on paddy rice, wheat, cotton, fruit trees and cruciferous vegetables. The metaflumizone-containing pesticidal composition enables the pesticide dosage to be reduced, is safe for human and livestock, does not have chemical injury, and has favorable environmental compatibility; the preparation has higher adhesive force and rainfall erosion resistance.
