Abstract

The invention discloses a preparation method and an application of a pesticide pyraclostrobin supported sample as well as the application of the pesticide pyraclostrobin supported sample in fluorescent tracing of pathogenic bacteria of asparagus stem blight. The preparation method of the pesticide pyraclostrobin supported sample comprises the following steps: (1) preparation of a supporter material: a mesoporous silica carbon quantum dot material is prepared as the supporter material; (2) the pesticide pyraclostrobin is supported on the mesoporous silica carbon quantum dot material, and the pesticide pyraclostrobin supported sample is obtained. The prepared pesticide pyraclostrobin supported system can support and release pyraclostrobin, can be used for inhibiting the pathogenic bacteria of asparagus stem blight and can be applied to fluorescent tracing of the pathogenic bacteria of asparagus stem blight.

Description

technical field [0001] The invention relates to the technical field of pesticide load application, in particular to a preparation method and application of a sample loaded with pesticide pyraclostrobin and its application in fluorescence tracing in pathogenic bacteria of reed stem blight. Background technique [0002] Mesoporous silica nanoparticles have unique properties such as light, electricity, and magnetism, a highly ordered and continuously adjustable mesoporous structure, a large specific surface area, easy modification of surface functional groups, and excellent biocompatibility. aroused widespread concern. Carbon quantum dots are the most important kind of fluorescent carbon nanomaterials. Compared with traditional semiconductor quantum dots and organic dyes, fluorescent carbon quantum dots have the advantages of small particle size, high chemical inertness, low toxicity and easy functionalization, and are widely used. in biomedical research. Doping carbon quantu...
