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.
