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

Abstract

The invention discloses a bactericidal composition containing bixafen and trifloxystrobin and an application thereof. The bactericidal composition is prepared from bixafen and trifloxystrobin which serve as main effective ingredients in a mass ratio of (1-70):(1-50). The bactericidal composition can be applied to prevention and control of diseases of cereals, fruit trees and vegetables, in particular prevention and control of powdery mildew, rust disease, damping-off, glume blight, net blotch, downy mildew, rice blast and other fungal diseases, has a relatively high synergistic effect, can be used for overcoming and delaying the drug resistance of germs, has the advantages of high bactericide speed, long duration and low application cost, and has the prevention and control effect superior to that of a single dose.
