Abstract

{0><}0{>The invention discloses a sterilization composition containing fluoride ether bacteria amide and thiophal and application of the sterilization composition. <0}{0><}0{>The sterilization composition takes the fluoride ether bacteria amide and the thiophal as main effective ingredients, and the mass ratio of the fluoride ether bacteria amide to the thiophal 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 thiophal. <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, rice blast, wheat rust disease, gibberellic disease, downy mildew of rape, leaf spot of peanut, early blight of tomato and anthracnose of apple, and achieves an effect obviously superior to that of the single fluoride ether bacteria amide or thiophal.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with fluotesamid and folpet 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 mildew, ca...
