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 different mechanisms of action is a common method to delay the development of disease resistance. The formula with a more obvious compounding effect can significantly improve the control effect and greatly reduce The amount of pesticide used can also expand the bactericidal spectrum and improve the bactericidal efficiency. There is no report on the compounding of flufeconazole and flufenapyramide

Embodiment 1

[0037] Example 1: 12% Chlorflufenazole · Flufenapyr Suspending Concentrate

[0038] Chlorfluconazole 6%, Flufenapyramide 6%, Polyoxyethylene Polyoxypropylene Block Copolymer 5%, Secondary Alkyl Sodium Sulfate 5%, Isothiazolinone 0.3%, Silicone Oil 0.2%, Xanthan Gum 1.5%, ethylene glycol 3%, and deionized water make up 100%, and the above substances are percentages by weight. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare 12% chlorofluconazole · flufenapyramide suspension concentrate.

Embodiment 2

[0039] Example 2: 30% Chlorflufenazole · Flufenapyr Suspending Concentrate

[0040]Chlorfluconazole 10%, Flufenapyr 20%, Dikestrobin 10%, Sodium Methylenebis-Naphthalene Sulfonate Formaldehyde Condensate 6%, Secondary Alkyl Sodium Sulfate 5%, Casone Kaisone 0.5% , 0.2% of silicone oil, 1.5% of xanthan gum, 3% of ethylene glycol, and 100% of deionized water, all of which are percentages by weight. Mix the above materials in proportion, disperse evenly through high-speed shearing, and sand-grind in a sand mill to prepare 30% chlorofluoroconazole · flufenapyramide suspension concentrate

Embodiment 3

[0041] Example 3: 20% chlorofluoroconazole·flufenapyramide aqueous emulsion

[0042] Chlorfluconazole 5%, Flufenapyramide 15%, Cyclohexanone 5%, Pine Base Oil 8%, Fatty Acid Polyethylene Glycol Esters 8%, Pentaerythritol 3%, Ethylene Glycol 2%, Silicone Compounds 0.2%, Casson 0.2%, gelatin 1%, and deionized water make up 100%, and the above substances are percentages by weight. The above-mentioned materials are mixed in proportion, and after being uniformly stirred by high-speed shearing, a 20% chlorofluconazole·flufenapyramide aqueous 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...
