Metconazole-containing synergistic reduction sterilizing composition

The invention relates to a metconazole-containing synergistic reduction sterilizing composition. The metconazole-containing synergistic reduction sterilizing composition is characterized in that the effective constituents of the sterilizing composition comprise 2-cyano-3-amino-3-ethyl phenylacrylate, the metconazole and fluxapyroxad, and the weight ratio of the 2-cyano-3-amino-3-ethyl phenylacrylate to the metconazole to the fluxapyroxad is (1-80):(1-80):(1-80); the metconazole-containing synergistic reduction sterilizing composition is used for controlling wheat scab, wheat powdery mildew, wheat rust, melon fusarium wilt, apple anthracnose, apple rot and fungoid diseases such as wheat sharp eyespot, rice blast and rice bakanae disease, and the synergy effect is obvious.
