A bactericidal composition containing fluorobactamil and phenoxystrobin and its application

Abstract

{0><}0{>The invention discloses a sterilization composition containing fluoride ether bacteria amide and metominostrobin and application of the sterilization composition. <0}{0><}0{>The sterilization composition takes the fluoride ether bacteria amide and the metominostrobin as main effective ingredients, and the mass ratio of the fluoride ether bacteria amide to the metominostrobin is (1 to 70) : (1 to 50). <0}{0><}0{>The sterilization composition can be applied to prevention and treatment of diseases of cereals, fruit trees and vegetables, has a relatively high synergistic effect, is capable of overcoming and retarding the drug resistance of pathogenic bacteria, is high in sterilization speed and long in lasting period, is capable of lowering the application cost, and achieves a prevention and treatment effect obviously superior to that of the single fluoride ether bacteria amide or metominostrobin. <0}{0><}0{>The sterilization composition can be used for preventing and treating fungi diseases of crops, especially can be used for preventing and treating fungi diseases such as downy mildew of grape, potato blight, rice sheath blight disease and rice blast, and achieves an effect obviously superior to that of the single fluoride ether bacteria amide or metominostrobin.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with fluoxystrobin and fenoxystrobin as main active ingredients and its application. Background technique [0002] Molecular formula: C 15 h 8 CIF 7 N 2 o 2 , Chemical name: N-(3-chloro-5-(trichloromethyl)pyridine-2-methyl)-2,3,5,6-tetrachloro-4-methoxybenzamide. The structural formula is as follows: [0003] [0004] Fluoreosyramide acts on the respiratory chain of fungal mitochondria, inhibits the activity of succinate dehydrogenase, thereby blocking electron transfer, inhibiting fungal spore germination, germ tube elongation, mycelial growth and spore mother cell formation of fungal growth and reproduction In the main stage, the bactericidal effect is directly caused by the active substance of the parent, and has no corresponding metabolic activity. It is highly effective against various fungal diseases such as grape downy mi...

Problems solved by technology

[0006] At present, the prevention and control of plant pathogens is becoming more and more difficult. On the one hand, with the change of planting structure, the planting area of ​​economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased, making the prevention and control more difficult. On the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous agent selection, the control effect of a single agent is greatly reduced, and the control of plant diseases is facing a major challenge
