Sterilization composition containing fluoxastrobin and fludioxonil and application thereof

Abstract

The invention discloses a sterilization composition containing fluoxastrobin and fludioxonil and application thereof. The sterilization composition is mainly prepared from fluoxastrobin and fludioxonil, wherein the weight ratio of fluoxastrobin to fludioxonil is (1-70):(1-50). The sterilization composition can be applied to preventing and treating of cereal, fruit tree and vegetable diseases, has the high synergistic interaction effect, overcomes and delays germ drug resistance, is high in sterilization speed and long in lasting period, reduces the application cost and has the better control effect than that of single dosages. The composition can be used for fungal diseases on crops, and can be particularly used for preventing rust diseases, glume blight, web blotch, powdery mildew, downy mildew, early blight, late blight, anthracnose, gray mold and other fungal diseases, and the effect is better than that of single dosages.

Description

Technical field [0001] The invention relates to a bactericidal composition and its use, in particular to a bactericidal composition with fluoxastrobin and fludioxonil 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 bactericidal activity, against almost all fungal diseases (ascomycetes, basidiomycetes, oomycetes and deuteromycetes) diseases such as rust, glumes, net spot, powdery mildew, frost Dozens of diseases such as mildew have good activity. [0005] Fludioxonil (Fludioxonil), molecular formula: C 12 H 6 F 2 N 2 O 2 , Chemical name: 4-(2,2-difluoro-1,3-benzodiox-4-yl)pyrrole-3-carbonitrile, chemical structure: [0006] [0007] Fludioxonil is derived from the natural product ...

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
