Water dispersible granules containing pyraclostrobin and preparation method thereof

The invention relates to water dispersible granules containing pyraclostrobin. The water dispersible granules containing pyraclostrobin comprise the following ingredients: 5%-80% of active ingredients, 1%-10% of a dispersing agent, 1%-8% of a wetting agent, 1%-10% of a disintegrating agent, 1%-5% of a binding agent and the balance of a filler. The preparation method comprises the steps of performing uniform mixing, ultrafine grinding, granulation, drying and sieving on the raw materials to obtain the water dispersible granules. The two compounded granules have an obvious synergistic effect than a mono-agent, the problems of difficult disintegration and the like of single pyraclostrobin or compounded water dispersible granules due to low melting point is solved, and the defects of dust flying and the like of wettable powder during production and use processes are overcome; the water dispersible granules have the advantages of high active ingredient content, high disintegration speed, good dispersity, high thermal stability, less environmental pollution and the like, has good control effects on wheat leaf rust, powdery mildew of cucumber, alternania mail Roberts and macrophoma musae when in use, and is high in safety.
