Abstract
The invention relates to the technical field of pesticides, in particular to a bactericidal composition for preventing and treating fruit and vegetable diseases and its application. The bactericidal composition of the present invention includes active components; the active components include tetramycin and novel succinate dehydrogenase inhibitor (SDHI) bactericides; the novel succinate dehydrogenase inhibitors The fungicide is one or more of flufenapyramide, fluopyram or pyraclostrobin. The bactericidal composition provided by the present invention and the pesticide preparation containing it not only maintain the control effects on botrytis cinerea, early blight, and gray leaf spot, but also can simultaneously treat sclerotinia, blight, dead trees, root-knot nematodes, and cankers. Effective prevention and control of succinate dehydrogenase inhibitor fungicides has been carried out to delay the occurrence of resistance to fungicides such as succinate dehydrogenase inhibitors. One spray for multiple preventions has been achieved, the control efficiency has been improved, and the goal of increasing production and income of vegetable farmers has been achieved.
Description
Technical field [0001] The present invention belongs to the field of pesticide technology, and specific to a bactericidal composition and application of prevention and treatment of fruits and vegetable diseases. Background technique [0002] The facilities of the facilities have higher income, but the temperature is high in temperature, high humidity, and conducive to the prosperity of pests and diseases, and severely restrict the safety production of facilities and vegetables. And because the facility vegetables are growing, it is difficult to plant difficulties, leading to the increasingness of the native disease, causing the premature failure of crops; the death rate of vegetables can reach 100%, seriously affecting the production and quality of the facility vegetables. [0003] The pathogenic bacteria caused by crop deaths (rhizoctonia.colani kuhn.), Rhosphericums (F. Squam), Rhizosporus tomato colicoid root rot disease (Fusarium oxysporum f sp.RADICIS- Lycopersici (FORL)) an...
