Abstract

The invention belongs to the field of bactericides, and discloses a bactericidal preparation of a composition containing a pyrazole amide compound (hereinafter referred to as a compound A) and a triazole bactericide as active components and application of the bactericidal preparation. The mass ratio of the two active components is 1: 50 to 50: 1, and the weight content of the active components in the composition is 10-80%. The composition comprises at least one carrier and at least one auxiliary agent. The composition can be prepared into missible oil, emulsion in water, microemulsion, a suspending agent, suspoemulsion, a dispersible oil suspending agent, wettable powder, water dispersible granules, a dry suspending agent and other dosage forms. The preparation disclosed by the invention has an excellent prevention and treatment effect on plant diseases caused by ascomycotina, basidiomycotina and deuteromycotina, and is safe to crops. The structural formula of the compound A is shown in the specification, wherein R1 is selected from hydrogen or methyl, and R2 is selected from methyl, ethyl, propyl or isopropyl.

Description

technical field [0001] The invention belongs to the field of fungicides, and relates to a preparation of a fungicide composition (containing a pyrazole amide compound A and a triazole fungicide) and an application thereof. Background technique [0002] At this stage, fungicide varieties containing a single active ingredient have defects of varying degrees in the process of preventing and treating fungal diseases: long-term use will easily cause fungi to develop drug resistance, reduce drug efficacy, fail to achieve good control effects, and at the same time have a narrow bactericidal spectrum. Through the compounding of two or more active components, the bactericidal effect can be enhanced, the service life of the agent can be extended, the bactericidal spectrum can be expanded, the control effect can be improved and the pollution to the environment can be reduced. [0003] However, pesticides themselves are a type of special chemicals with biological activity. Although the ...
