The invention discloses a compound composition of 2-cyano-3-amino-3-phenyl ethyl acrylate and ethylicin and an application thereof, and belongs to the pesticide field. The compound composition provided by the invention comprises the active ingredients: 2-cyano-3-amino-3-phenyl ethyl acrylate and ethylicin, wherein the mass ratio of 2-cyano-3-amino-3-phenyl ethyl acrylate to ethylicin is (1-36):6; and the composite has not been reported at present. After the compound composition provided by the invention is prepared into a pesticide, the pesticide can be used for effectively preventing verticillium wilt of strawberry, bakanae disease of rice and gibberellic disease of wheat; the control effect of the pesticide is obvious and the use of missible oil is avoided; in relation to independent use of 2-cyano-3-amino-3-phenyl ethyl acrylate, the pesticide prepared from the compound composition is still capable of achieving control effect similar to that of 25% 2-cyano-3-amino-3-phenyl ethyl acrylate suspending agent, and the active ingredient ethylicin greatly reduces the production cost; besides, the compound bactericidal composition is capable of obviously improving the prevention and treatment effects and the dosage of the pesticide is reduced; therefore, the compound composition becomes an important tool for comprehensively preventing and treating various diseases.
