Abstract

The invention discloses a bactericidal composition with pyraclostrobin and xinjunan acetate. Active components of the bactericidal composition are the pyraclostrobin and the xinjunan acetate, and a weight ratio of the pyraclostrobin to the xinjunan acetate is 10:1-1:10. The bactericidal composition further can comprise pesticide science permitted and acceptable auxiliaries or / and fillers. The bactericidal composition can be in dosage forms of wettable powder, suspending agents, missible oil or water-dispersible granules. The bactericidal composition can be applied to preventing and treating diseases of fruit trees, branches and trunks of forest trees, vegetables and field crops and particularly can be applied to preventing and treating apple rot, apple powdery mildew, grape powdery mildew, grape downy mildew and cucumber downy mildew. The bactericidal composition has the advantages that synergistic interaction effects can be realized by the bactericidal composition, and accordingly prevention and treatment effects can be improved; bactericidal spectra can be expanded; action mechanisms of the two effective components are different from one another, the two effective components are mixed and used with each other, and accordingly insecticide resistance of pathogenic bacteria can be delayed; the application dosage can be reduced, the service frequencies can be decreased, and accordingly the service cost can be lowered.

Description

technical field [0001] The invention relates to a bactericidal composition containing pyraclostrobin and octocalid acetate and an application thereof, which belongs to the technical field of pesticide prevention and control. Background technique [0002] The use of chemical agents for prevention and control in agricultural production is inevitable to produce resistance, and the development of new compounds with insecticidal and bactericidal activities is costly and takes a long time, and cannot keep up with the speed of disease resistance. Therefore, it is a better choice to compound two compounds with different mechanisms of action and synergistic effects. [0003] Pyraclostrobin: CAS number: 175013-18-0, molecular formula: C19H18ClN3O4, molecular weight: 387.8169, melting point: 63.7~65.2℃. The pure product is white to light beige odorless crystals; pyraclostrobin technical rat acute oral LD5000mg / kg, acute percutaneous LD2000mg / kg, acute inhalation LCso(4h)0.3lmg / L; no e...
