The invention relates to the technical field of microbial pesticides, in particular to a complex
microbial inoculant for preventing and treating garlic diseases and a preparation method and application thereof.The complex
microbial inoculant is composed of seven strains including
bacteria and fungi T4, JR14, BR55, A25, BR33, BR43 and JR22, experiments prove that the complex
microbial inoculant has excellent garlic pathogenic bacterium
hypha inhibition and sporulation inhibition effects, and the complex microbial inoculant can be used for preventing and treating garlic diseases. All bacterial and fungal candidate strains participate in inhibition of fungal pathogens through synergistic interaction. The
potting effect verifies that the growth of garlic plants is severely influenced under the stress of T9
pathogenic bacteria, but the complex microbial inoculant disclosed by the invention not only can keep the
normal growth of the garlic plants and has no obvious difference with the
plant height of the plants growing in normal soil, but also has a certain effect of promoting the growth of the garlic plants.
