Problems solved by technology

[0006] In recent years, the prevention and control of plant pathogens has become more and more difficult. First, due to the change of planting structure and the gradual expansion of planting area, the incidence and number of diseases have increased; The pressure increases year by year, and the control effect of a single agent is greatly reduced. The compounding of active ingredients with diff

Example Embodiment

[0037] Example 1: 12% clofluconazole·fluconazole suspension

[0038] Clofluconazole 6%, trifluconazole 6%, polyoxyethylene polyoxypropylene block copolymer 5%, secondary alkyl sulfate 5%, isothiazolinone 0.3%, silicone oil 0.2%, xanthan gum 1.5%, ethylene glycol 3%, deionized water to make up 100%, the above substances are percentages by weight. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sanded in a sand mill to obtain a 12% clofluconazole·fluconazole suspension.

Example Embodiment

[0039] Example 2: 30% clofluconazole·fluconazole suspension

[0040] Chlorfluconazole 10%, Fluconazole 20%, Difenoxystrobin 10%, Methylene Dinaphthalene Sulfonate Sodium Formaldehyde Condensate 6%, Secondary Alkyl Sodium Sulfate 5%, Cassonkasone 0.5% , Silicone oil 0.2%, xanthan gum 1.5%, ethylene glycol 3%, deionized water to make up 100%, the above substances are percentages by weight. Mix the above-mentioned materials according to the proportion, disperse uniformly through high-speed shearing, and sand in a sand mill to obtain 30% clofluconazole·fluconazole suspension

Example Embodiment

[0041] Example 3: 20% clofluconazole·fluconazole water emulsion

[0042] Clofluconazole 5%, fluconazole 15%, cyclohexanone 5%, pine base oil 8%, fatty acid polyethylene glycol ester 8%, pentaerythritol 3%, ethylene glycol 2%, silicone compounds 0.2%, Casson Kasson 0.2%, gelatin 1%, deionized water to make up 100%, the above substances are all weight percentages. The above-mentioned materials are mixed according to the proportion, and after high-speed shearing and stirring are uniform, a 20% clofluconazole·fluconazole water emulsion can be prepared.

Abstract

The invention discloses a bactericidal composition containing mefentrifluconazole and fluxapyroxad. The bactericidal composition is characterized by containing active ingredients of mefentrifluconazole and fluxapyroxad, the mass ratio of mefentrifluconazole to fluxapyroxad is 1:50 to 50:1, preferably, 1:30 to 30:1, more preferably, 1:20 to 20:1, further more preferably, 1:10 to 10:1, and the mostpreferably, 1:1, 1:2, 1:3, 1:5, 2:3, 5:7, 2:1 and 3:8, and the active ingredients of mefentrifluconazole and fluxapyroxad account for 1%-80% of the mass of the composition. Mefentrifluconazole and fluxapyroxad are compounded in a certain proportion, so that the bactericidal composition has a higher control effect on botrytis cinerea and rice sheath blight.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to the application of a fungicidal composition containing flufenazole and flufenapyramide on crop diseases. Background technique [0002] Mefentrifluconazole is a broad-spectrum, high-efficiency, systemic fungicide with eradicating and protective effects. It exhibits excellent biological properties and is expected to become an important tool for efficient disease control and will be used to slow down Development of resistance to fungicides. Studies have shown that flufeconazole has outstanding biological activity against many refractory fungal diseases, and is suitable for many field crops and special crops worldwide, such as corn, grain, soybean and economic crops. It is reported that chlorofluoroconazole is more effective than prothioconazole and epoxiconazole. [0003] The chemical structure of flufeconazole is shown below: [0004] [0005] Fluxapyroxad chem...
