Fungicidal composition containing fluoxastrobin and tebuconazole and application of composition

Abstract

The invention discloses a fungicidal composition containing fluoxastrobin and tebuconazole and application of the composition. According to the fungicidal composition, fluoxastrobin and tebuconazole serve as main effective components, and the mass ratio of fluoxastrobin to tebuconazole is 70:1-1:50. The fungicidal composition can be applied to preventing diseases of cereal, fruit trees and vegetables, has a high synergistic function, overcomes and delays the insecticide resistance of germs, is high in fungicidal speed and long in lasting time, reduces the application cost, and has the prevention effect which is obviously better than that of single fungicides in use. The fungicidal composition can be used for preventing fungal diseases on crops, can be particularly used for preventing head blight, the rust disease, powdery mildew, net blotch, root rot, smut, downy mildew, rice sheath blight and other fungal diseases, and has effects better than those of the single fungicides in use.

Description

[0001] Technical field: [0002] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with fluoxastrobin and tebuconazole 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, glume blight, net spot, powdery mildew, downy mildew and other dozens of diseases have...

AI Technical Summary

Problems solved by technology

[0007] However, scab, rust, powdery mildew, net spot, root rot, smut, downy mildew and rice sheath blight are more serious, causing catastrophic losses to agricultural production, although fluoxastrobin, A single dose of tebuconazole has a relatively ideal control effect on some diseases, but in practical applications, it is found that the control of plant pathogens is becoming more and more difficult. The main reasons are as follows: First, with the change of planting structure, fruits, vegetables The planting area of ​​economic crops such as ect. is gradually expanding, and the degree and number of diseases have increased, making it more difficult to control; second, the current abnormal climate provides certain conditions for the outbreak of diseases; third, the choice of long-term chemical drugs Sexual impact, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous agent selection, and the control effect of a single agent is greatly reduced

In summary, the current plant disease control is facing major challenges
