[0108] Experimental Example 1 Indoor bioassay test

[0109] Using the potted method indoors, the inhibitory effect of different agents on the growth of grape powdery mildew (Uncinula necator) was determined, and the EC of each agent on the pathogenic bacteria was calculated. 50 value.

[0110] Pesticide application: Potted grape seedlings with the same growth at the two-leaf stage were selected for the experiment. A single dose or each composition (see Tables 1-4) was dissolved in dimethyl sulfoxide and then diluted to 50 mg / L by adding 0.1% Tween 80 water. After spraying the stems and leaves, the test materials were dried in the shade for 24 hours.

[0111] Inoculation: Wash the fresh spores on the diseased grape leaves with water added with a small amount of Tween, filter through double-layer gauze to make a spore suspension, and spray evenly on the seedlings with an inoculation sprayer for inoculation. After inoculation, the potted grape seedlings were placed in the gree...

Abstract

The invention relates to a sterilization composition containing Isoflucypram and a methoxy acrylate bactericide, and a preparation and an application thereof. The methoxy acrylate bactericide is any one of pyraclostrobin, picoxystrobin, kresoxim-methyl and coumoxystrobin, wherein a mass ratio of the effective component Isoflucypram to the methoxy acrylate bactericide is (1-15):(15-1), and the total content of the Isoflucypram and the methoxy acrylate bactericide in the sterilization composition / preparation is from 1-80 mass%. The sterilization composition / preparation has a significant synergistic effect on the control of grape powdery mildew. The sterilization composition and the preparation are suitable for preventing and controlling powdery mildew, rust, glume blight, net blotch, downy mildew, rice blast and other diseases. The composition has the advantages of obvious synergistic effects of the active components, delaying of the pesticide resistance of pathogens, reduction of the pollution to the environment, and excellent practical values when applied to prevent and control crop diseases.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal composition containing Isoflucypram and methoxyacrylate bactericides. Background technique [0002] Isoflucypram (development code: BCS-CN88460) is a pyrazole carboxamide fungicide, which belongs to a new type of succinate dehydrogenase inhibitor (SDHI). function of acid dehydrogenase. The chemical name of Isoflucypram is N-[[5-chloro-2-(1-methylethyl)phenyl]methyl]-N-cyclopropyl-3-(difluoromethyl)-5-fluoro-1 -Methyl-1H-pyrazole-4-carboxamide. Isoflucypram has systemic conductivity, and has the characteristics of resistance to rainwater and has high-efficiency fungicidal activity against powdery mildew and gray mold. The structural formula of Isoflucypram is: [0003] [0004] Pyraclostrobin is a methoxyacrylate fungicide, and it is a mitochondrial respiration inhibitor. That is, it prevents electron transfer during cytochrome synthesis. The a...
