Imidacloprid microbial seed dressing agent and preparation method thereof

The invention discloses an imidacloprid microbial seed dressing agent and a preparation method thereof. The imidacloprid microbial seed dressing agent is prepared from the following raw materials in parts by weight: 350-650 parts of imidacloprid, 300-400 parts of furfural residues, 10-100 parts of boric magnesium slag, 3-5 parts of beauveria bassiana conidial powder, 0.5-1.5 parts of photosynthetic bacteria and 1-2 parts of enzyme microorganism. The method comprises the following steps: diluting the photosynthetic bacteria and the enzyme microorganism by water, and evenly mixing, so as to obtain a composite bacterium solution; taking the furfural residues, adding all prepared composite bacterium solution, and fermenting to obtain a furfural residue fermented material; adding the imidacloprid, the boric magnesium slag and the eauveria bassiana conidial powder to the prepared furfural residue fermented material; and baking and crushing, so as to prepare the imidacloprid microbial seed dressing agent. The imidacloprid microbial seed dressing agent has the advantages of being free of damage to seeds, long in action time, and good in crop growth promoting effect, underground pests can be effectively prevented and removed, and the seed germination rate is ensured.
