Sterilization composition with fluoxastrobin and zineb and application of sterilization composition

Abstract

The invention discloses a sterilization composition with fluoxastrobin and zineb and application of the sterilization composition. The sterilization composition comprises the fluoxastrobin and the zineb which are main effective components. A weight ratio of the fluoxastrobin to the zineb is 1-70:1-50. The sterilization composition and the application have the advantages that the sterilization composition can be applied to preventing and treating diseases of cereals, fruit trees and vegetables, excellent synergistic effects can be realized by the sterilization composition, the insecticide resistance of germs can be overcome and delayed, the sterilization composition is high in sterilization speed and long in lasting period, the application cost can be reduced, and prevention and treatment effects of the sterilization composition are superior to prevention and treatment effects of single-dosage application; the sterilization composition can be used for preventing and treating the fungi diseases of crops and particularly can be used for preventing and treating the fungi diseases such as rust diseases, glume blight, net blotch, powdery mildew, downy mildew, early blight, late blight and anthracnose, and the effects of the sterilization composition are superior to the effects of single-dosage application.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with fluoxastrobin and zinc zinc 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 a broad-spectrum fungicidal activity against almost all fungal diseases (Ascomycetes, Basidiomycetes, Oomycetes and Deuteromycetes) such as rust, glume blight, net spot, powdery mildew, frost Mildew and other dozens of diseases have very good activity. [0005] Zinc (Zineb), the pure product is a white powder, no odor, the industrial product is off-white or light yellow, with a peculiar smell. No melting point. Vapor pressure <0.0lmPa (20°C). The solubilit...

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
