However, not any two pesticide single agents can be compounded and used in this way, because there are also problems in this compounding. For example, although some active ingredients have no problem in their respective use, after compounding and using, they will produce The intermediate products may have adverse chemical reactions and cause environmental pollution problems
At present, there is no report on the combination of benzathystrobin and propiconazole

Abstract
The invention relates to a sterilizing composition containing benzothiostrobin and triazole fungicide. The sterilizing composition comprises active ingredients and auxiliary elements of a pesticide preparation, wherein the active ingredients comprise benzothiostrobin and triazole fungicide; the mass ratio of the benzothiostrobin to the triazole fungicide is (1:50)-(50:1); the triazole fungicide is one of tebuconazole, flutriafol, triadimefon, propiconazole and hexaconazole. The benzothiostrobin and the triazole fungicide of the sterilizing composition are two sterilizing agents having different mechanisms and are not subjected to conflicts after being compounded, a remarkable synergistic effect on the resistant bacteria is achieved within a certain scope, the sterilizing composition has a remarkable control effect, is safe and does not damage crops, the acute toxicity on a mammal is reduced after the benzothiostrobin and the triazole fungicide are compounded, and the safety is improved. The field trial shows that the sterilizing composition expands the bacteriocidal spectrum and has special effects on diseases of the crops such as powdery mildew, leaf spot disease, false smut, scab, banded sclerotial blight, damping-off and the like, and the use amount of the sterilizing composition is less.
Description
Technical field [0001] The present invention belongs to the technical field of pesticides, and specifically relates to a bactericidal composition containing mefenthiazole and propiconazole, and also relates to the application of the bactericidal composition. Background technique [0002] Methoxyacrylate fungicides are new fungicides developed by natural antibiotic Strobilurin A as the lead compound. This kind of fungicides has the functions of protection, treatment, eradication, and penetration, and can effectively prevent plant diseases caused by fungi such as ascomycetes, basidiomycetes, deuteromycetes and oomycetes. Benthiastrobin is a new type of methoxy acrylate fungicide developed by Central China Normal University. Benthiastrobin has the characteristics of wide bactericidal spectrum, high bactericidal activity, and long lasting time. It is a common white powder for fruit trees, vegetables and field crops. Diseases, rust, leaf spot, brown spot, downy mildew and rice blast ...
