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 sterilizing composition containing bixafen and tebuconazole and application thereof. The sterilizing composition uses bixafen and tebuconazole as main effective ingredient, wherein a mass ratio of the bixafen to the tebuconazole is 1-70:1-50. The sterilizing composition is applicable to the prevention and treatment of grass, fruit tree and vegetable diseases and has high synergism, pathogenic drug resistance is overcome and delayed, sterilizing speed is high, sterilizing duration is long, application cost is lowered, and the preventive and treatment effect is significantly higher than that of use of a single agent. The sterilizing composition may be used to prevent and treat leaf spot, leaf rust, downy mildew, rice blast, damping-off and other fungal diseases and is significantly effective than the use of a single agent.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with bixafen and tebuconazole as main active ingredients and its application.
