Common name in English: Bacillus subtilis, a Gram-positive bacterium.
Its bactericidal mechanism mainly includes:
1) After Bacillus subtilis is sprayed on the plant surface, its live spores absorb and utilize nutrients and water, reproduce and occupy the leaf surface, and compete with pathogenic bacteria for nutrients and living space;
2) secrete antibacterial active substances, which have bacteriolytic effects and biological oxygen-snatching effects, and can effectively repel, inhibit and kill pathogens, achieving the effect of preventing and controlling diseases.
