Chlopyrifos emulsifiable granules and preparation method thereof

The invention relates to chlopyrifos emulsifiable granules and a preparation method thereof, and relates to an agricultural bactericide. The chlopyrifos emulsifiable granules comprise the following raw materials in percentage by weight: 20%-60% of chlopyrifos, 5%-10% of emulsifying agent, 8%-12% of water-soluble polymer, and the balance of carriers. The preparation method comprises the following steps: mixing liquid chlopyrifos and the emulsifying agent uniformly firstly; adding chlopyrifos after mixing into a water solution of the water-soluble polymer, and mixing uniformly, thus viscous emulsion is obtained; then adding the carriers into the viscous emulsion, thus a pre-granulating mixture is obtained; and finally granulating and drying. The granules provided by the invention have quick acting and duration, can be completely emulsified by adding water in use, and can achieve good effect at low concentration; and bactericidal effect is superior to other dosage forms with the same active ingredients.
