Problems solved by technology

Due to the long development cycle and high cost of new pesticides, the compounding of existing pesticides can delay the emergence of bacterial resistance, improve the actual control effect, expand the bactericidal spectrum and reduce the cost of medication. It is an important means of comprehensive disease prevention and control.
There is no report on the application of thifuramide and difenoconazole as active ingredients for the control of rice sheath blight and plant diseases such as fruit trees and vegetables.

Abstract

The invention relates to a disinfection composite containing thifluzamide and difenoconazole, in particular to a disinfection composite by taking thifluzamide and difenoconazole as effective ingredients; the disinfection composite is mainly used for disease control such as preventing banded sclerotial blight of rice and leaf spot, powdery mildew, rust disease and Cladosporium cucumerinum and the like of various vegetables and fruit trees; the disinfection composite contains the thifluzamide and the difenoconazole as effective ingredients, and the mass proportion of the thifluzamide and the difenoconazole is from 1:50 to 50:1; the disinfection composite has the advantages that: firstly, after the thifluzamide and the difenoconazole are mixed, the disinfection effect is improved and the dosage is reduced; secondly, after the thifluzamide and the difenoconazole are mixed, disinfection spectrum is expanded and the advantages of the drug characteristics are complemented with each other, one kind of the drug can prevent various crop pests, so as to be convenient for farmers to use; thirdly, after the thifluzamide and the difenoconazole are mixed, the resistance of pathogenic bacteria to drugs is prolonged, thereby having important significance to disease resistance and comprehensive treatment.

Description

technical field [0001] The invention relates to a bactericidal composition containing thifluzamide and difenoconazole, in particular to a bactericidal composition using thifluzamide and difenoconazole as active ingredients. The invention is mainly used for the prevention and treatment of rice sheath blight and the prevention and treatment of diseases such as leaf spot, powdery mildew, rust and scab of various vegetables and fruit trees, and belongs to the field of pesticide compositions. Background technique [0002] Thiofuramide, also known as thiafluzamide, the common name in English is Trifluzamide, which belongs to the thiazole amide fungicides, and has strong systemic conductivity and long-lasting effect. Thiofuramide is a succinate dehydrogenase inhibitor. Due to its fluorine content, it has strong competitiveness in biochemical processes, and it is not easy to recover once it is combined with a substrate or enzyme. Thiofuramide has special effects on diseases caused ...
