The invention discloses a prothioconazole-triclopyricarb suspending agent and a preparation method thereof, and belongs to the technical field of
pesticide preparations. The bactericidal composition is prepared from prothioconazole
active compound, triclopyricarb
active compound, a dispersing agent, a
wetting agent, an anti-freezing agent, a
thickening agent, a defoaming agent, a
preservative and deionized water. The preparation method comprises the steps of preparation of a
thickening agent aqueous solution, preparation of an aqueous phase
system, high-speed shearing and pre-dispersion, sanding and refining,
slurry recovery, homogenization and
complementation, finished product detection and
verification and the like, and key parameters are accurate and controllable. Through a synergistic stabilization mechanism of electrostatic repulsion dispersion and three-dimensional network fixation and in combination with refined
process design, the technical problems that an existing compound suspending agent is prone to agglomeration, layering and
precipitation and poor in stability are solved, meanwhile, synergistic interaction of the two raw drugs is achieved, the bactericidal spectrum is expanded,
drug resistance is delayed, and the preparation process is scientific, efficient, high in
operability and suitable for industrial production. The method has both
environmental protection benefits and
economic benefits, and has wide application prospects.
