The invention belongs to the technical field of microbial biopesticides, and particularly relates to a high-efficiency, low-
toxicity and environment-friendly
microbial pesticide, which is characterized in that effective components of the high-efficiency, low-
toxicity and environment-friendly
microbial pesticide are formed by compounding microbial
active components and compounding factors; wherein the microbial
active component is P.megatherium; the microbial
active component is P.megatherium; the compound factor is physcion or
berberine. The bacterium content of the microbial
active component, namely, the preristeria megatherium, is 5.0 * 10 < 10 > cfu / g, and the preristeria megatherium has a relatively good inhibition effect on the growth of fungal
pathogenic bacteria mycelia and has the potential of being developed into a microbial bactericide; when the compound is compounded with the existing
biopesticide physcion or
berberine, the compounded composition has a synergistic effect on the growth of fungal
pathogenic bacteria hyphae of crops, and compared with the
single use of the microbial active component, the compound composition can improve the prevention and
treatment effect on diseases, is beneficial to reducing the application amount of the
pesticide, and has a good application prospect. And the method is of great significance to development of compound microbial biopesticides.
