The invention relates to a preparation method of a pesticide suspoemulsion, and belongs to the technical field of pesticides, and the preparation method comprises the following steps: S1, preparing an aqueous solution dispersion system of a solid pesticide active compound; s2, preparing an emulsion phase of a liquid pesticide raw material; s3, adding the emulsion phase into an aqueous solution dispersion system by using a high-speed shear mixer until the particle size of the liquid pesticide raw material reaches a nanometer level; and S4, adding an initiator into the system in S3, uniformly mixing, heating to 40-60 DEG C, keeping the stirring speed at 800-1000r/min, and reacting for 4-6 hours to obtain the ultra-stable pesticide suspoemulsion. The invention not only overcomes the defects of poor physical stability and difficult transportation and storage of the traditional suspoemulsion, but also does not need to add the traditional thickening agent and suspending aid, and has the advantages of simple auxilia
