The invention discloses a trifloxystrobin-containing compound 
pesticide bactericidal composition. The effective ingredients comprise a component A and a component B; the 
mass ratio of the component A to the component B is 70:1-1:70; the component A is trifloxystrobin; and the component B is one of SYP-1620, mandipropamid, mepanipyrim, 
fluopicolide and 
orysastrobin. The invention also discloses a preparation prepared from the composition and suitable for agricultural application. Compared with the simplex trifloxystrobin, the compound bactericidal composition disclosed by the invention has the advantages of obvious synergistic action on various diseases such as 
downy mildew, 
rust disease, 
powdery mildew, 
leaf spot disease, scab and rice blast, thus improving the 
control effect; functional mechanisms of the effective ingredients in the bactericidal composition are different from each other, thereby facilitating to overcome the 
disease resistance and 
delay the generation of the 
drug resistance of pests, greatly increasing the dosage of the 
pesticide in the field, effectively decreasing the environmental 
pollution and the 
pesticide residue, and reducing the production and use costs; additionally, according to the trifloxystrobin-containing compound pesticide bactericidal composition disclosed by the invention, the 
fungicide spectrum is enlarged and the comprehensive control of 
crop diseases is benefited.
