Problems solved by technology

[0007] 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

Abstract

The invention discloses a sterilization composition containing fluoxastrobin and coumoxystrobin and application thereof. The sterilization composition is composed of main active components of fluoxastrobin and coumoxystrobin, wherein the mass ratio of the fluoxastrobin to the coumoxystrobin is (50:1)-(1:60). The sterilization composition can be used for controlling cereal, fruit tree and vegetable diseases, and can be particularly used for controlling downy mildew, late blight, banana freckle, anthracnose, leaf mold, glume blight, powdery mildew and other fungal diseases; and the sterilization composition has higher synergic action, overcomes and postpones the drug resistance of pathogenic bacteria, has the advantages of high sterilization speed, long duration period and lower application cost, and has an obviously better control effect than a single agent.

Description

[0001] Technical field: [0002] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with fluoxastrobin and syringstrobin as main active ingredients and its application. Background technique [0003] Fluoxastrobin (Fluoxastrobin) is a mitochondrial respiration inhibitor. Its mechanism of action is to inhibit mitochondrial respiration through electron transfer between cytochrome b and C1. Good compatibility and appropriate processing can further improve its penetration into the leaves through the cuticle. Although it has poor absorption capacity through seeds and roots, when used as a seed treatment agent, it has good killing and persistent effects on seedlings and seed-borne and soil-borne diseases, and it has a good effect on almost all fungi (Ascomycetes). , Basidiomycetes, Oomycetes and Deuteromycetes) diseases such as rust, glaucoma, net spot, powdery mildew, downy mildew and other dozens of diseases have ve...
