The invention provides a preparation method of a bio-based pesticide, which relates to the technical field of biological pesticide preparation. It is composed of 20-30 grams of active biological bacteria such as fungi, Beauveria bassiana or bacteria, thuringiensis thuringiensis, by weight per 500ml unit volume, with a concentration of 20% 500ml of monomolecular organic matter containing unsaturated double bonds and an appropriate amount of cross-linking. agent, initiator, stabilizer and 150-160 grams of starch nutrients are mixed together. The preparation process is as follows: mixing the above components and contents at 40-45 DEG C for 30 minutes, molding and drying at 35 DEG C to obtain a finished product. The biological fungus has strong insecticide resistance, prolongs field activity for 2 months, and has a control effect of 86 percent. The product has abundant raw materials and simple production process. |
