Compound pesticide capable of preventing and treating green plant bug and preparation method of compound pesticide

The invention belongs to the technical field of compound pesticides and specifically relates to a compound pesticide capable of preventing and treating green plant bug and a preparation method of the compound pesticide. The compound pesticide is prepared from pymetrozine and malathion as active ingredients; the advantages of the pymetrozine and the malathion can be complemented; the advantages, namely long residual life of the pymetrozine and good fast-acting property of the malathion, are developed, and the disadvantage of no systemic property of the malathion is also overcome, and therefore, the pesticide effect is remarkably improved and an obvious synergistic effect can be achieved; the compound pesticide is remarkable in the effect of preventing and treating green plant bug, and also has the effects of reducing the spraying times, delaying the resistance, prolonging the service life of the old and new varieties and reducing the cost and the environmental pollution.
