Desflurane bacteria amide and metconazole-containing sterilization composition and application thereof

Abstract

The invention discloses a desflurane bacteria amide and metconazole-containing sterilization composition and application thereof. The sterilization composition contains desflurane bacteria amide and metconazole which serve as main effective components, wherein the mass ratio of desflurane bacteria amide to metconazole is (1-70):(1-50). The sterilization composition can be applied to prevention and treatment of cereal, fruit tree and vegetable diseases, and is better in synergetic effect; the drug resistance of bacteria can be overcome and delayed; the sterilization speed is high, the lasting period is long, and the application cost is reduced; the prevention and treatment effect is obviously better than those of other single dosages. The desflurane bacteria amide and epoxiconazole-containing sterilization composition can be used for preventing and treating fungoid on crops, particularly for preventing and treating fungal diseases such as downy mildew, potato late blight, rice sheath blight, cotton seedling damping-off, wheat powdery mildew, wheat glume blight and wheat rust, and such prevention and treatment effect is obviously better than that of the single dosage.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its use, in particular to a bactericidal composition with flufenoxamide and metconazole as main active ingredients and its application. Background technique [0002] Flufenostamide molecular formula: C 15 H 8 ClF 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] Flufenostamide 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, hypha growth and spore mother cell formation, fungal growth and reproduction In the main stage, the bactericidal effect is directly caused by the active substance of the parent body, and has no corresponding metabolic activity. It has high resistance to various fungal diseases such as grape downy mildew, phytophth...

AI Technical Summary

Problems solved by technology

[0008] 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
