Sterilization composition containing fluoxastrobin and simeconazole and application thereof

Abstract

The invention discloses a sterilization composition containing fluoxastrobin and simeconazole and an application thereof. The sterilization composition takes fluoxastrobin and simeconazole as the main effective components, wherein the weight ratio of the fluoxastrobin to simeconazole is 1-70:1-50. The sterilization composition can be used for preventing and treating cereals, fruit trees and vegetables disease, has high synergistic interaction effect, overcomes and delays pathogen resistance, has fast sterilization speed and long persistent period, and reduces application cost, the control effect is obviously better than that of a single dose. The sterilization composition containing fluoxastrobin and simeconazole can be used for preventing and treating fungi diseases on crops, and especially can be used for preventing and treating rust, glume blight, net blotch, powdery mildew, downy mildew, venturia inaequalis, seedling blight, and sheath blight, and the effect of the sterilization composition is obviously better than that of a single dose.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with fluoxastrobin and silfluazole as main active ingredients and its application. Background technique [0002] Fluoxastrobin (Fluoxastrobin), molecular formula: C 21 h 16 C l FN 4 o 5 , chemical name: {2-[6-(2-chlorophenoxy)-5-fluoropyrimidin-4-yloxy]phenyl}(5,6-dihydro-1,4,2-dioxazine- 3-yl) ketone O-methyl oxime, structural formula: [0003] [0004] Fluoxastrobin has broad-spectrum bactericidal activity, and is effective against almost all fungal diseases (Ascomycetes, Basidiomycetes, Oomycetes and Deuteromycetes) such as rust, glaucoma, net spot, powdery mildew, frost Mildew and other dozens of diseases have very good activity. [0005] Simeconazole (simeconazole), molecular formula: C 14 h 20 FN 3 OSi, chemical name: (RS)-2-(4-fluorophenyl)-1-(1H-1,2,4-1 trioxane-1-yl)-3-trimethylsilylpropane-2- Alcohol, chemical str...

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
