The invention provides a suspension concentrate of Zn Thiodiazole and preparationthereof. The suspension concentrate comprises Zn Thiodiazole 5-60%, wettingagent 2-8%, dispersant 2-5%, thickening agent 0-3%, antifreezing agent 0-5%,preservative agent 0-0.5%, antifoaming agent 0-0.5% and water the rest. Thesuspension concentrate can be prepared by grinding with sand-mill, homogenizingby high-speed shearing combined with sanding, or homogenizing by high-speedshearing combined with homogenizing by high pressure. The product possessesstrong control effect for bacterial diseases, e.g. bacterial leaf-blight ofrice, bacterial strips and canker of citrus. Its advantages comprise low environmentalpollution, low toxicity superior formulation property such as no precipitationor stratification when stored at room temperature for two years, long shelf life,noninflammable, and safe for storage and transportation.
