Core Overview
Unlike polymyxin (an antibiotic substance), Bacillus amyloliquefaciens is a living bacterium. Its function is not to directly "kill", but to affect plants, pathogens and the soil environment through its life activities and metabolic products. Its most notable characteristic is the ability to produce an efficient antibiotic - polymyxin.
Mechanism of Action (Multifunctionality)
Competitive Action
Spatial Competition: By rapidly colonizing and reproducing in the rhizosphere of plants, on their surfaces, or in the soil, it forms an advantageous bacterial community, seizing positions and occupying the survival space of pathogens.
Nutritional Competition: It prioritizes the absorption of nutrients such as carbon, nitrogen, and iron in the soil, causing pathogens to "starve".
Antagonistic effect (production of antibacterial substances)
This is its most fundamental disease prevention mechanism. It can produce various antibacterial substances to directly inhibit or kill pathogenic bacteria:
Antibiotic types: such as polymyxins, corynecins, etc., have specific effects on various Gram-negative bacteria (such as Erwinia, Pseudomonas).
Antibacterial proteins/peptides: such as bacteriocins, chitinases, etc., can dissolve the cell walls of fungi.
Other inhibitory substances: such as surfactant lipopeptides, etc.
Inducing system resistance
This is a "vaccination" effect. The Bacillus amyloliquefaciens itself does not directly attack the pathogenic bacteria; instead, it activates the plant's own defense system, putting the plant in a "warning" state. When the real pathogenic bacteria attack, the plant can respond more quickly and strongly. This resistance is systemic and can protect the entire plant.
Promotion effect
Nitrogen fixation: Convert nitrogen in the air into nitrogen that plants can absorb.
Phosphorus and potassium release: Decompose the fixed phosphorus and potassium in the soil to make them available for plant absorption.
Production of plant hormones: Secretion of plant growth regulators such as indole acetic acid (IAA), stimulating root development.
Main Target Diseases and Applications
Bacterial diseases
Bacterial wilt (for tomatoes, peppers, tobacco, etc.) - This is its key target for control.
Soft rot (for Chinese cabbage, potatoes, etc.).
Canker (for citrus, etc.).
Fungal diseases
Root rot, wilt (for citrus, etc.).
Sudden death, damping off, seedling blight.
Application methods
Soil treatment / root irrigation: The primary method for controlling soil-borne diseases.
Seed mixing / soaking: Protecting young seedlings.
Spraying: Preventing leaf diseases.
Key Features
Broad-spectrum antibacterial
Effective against various bacterial and fungal diseases, especially adept at controlling stubborn soil-borne diseases.
01
Multiple mechanisms
Combining competitive, antagonistic, inducing resistance, and promoting symbiosis, the effect is stable and less likely to develop resistance.
02
Promotes growth and increases yield
While preventing diseases, it can significantly promote plant growth, increase yield and quality.
03
Environmentally friendly
As living microorganisms, it is non-toxic, harmless, and has no residual pollution, meeting the requirements of organic agriculture.
04
High tolerance to adverse conditions
Its endophytic spores can withstand high temperatures, drought, and adverse environments, facilitating the production, storage, and transportation of the microbial agent.
05
Usage Notes
Prevention-oriented
As a biological agent, its main function is to prevent and promote health. It should be used before or during the early stage of disease occurrence.
01
Avoid mixing with fungicides
Do not mix it with broad-spectrum chemical fungicides (especially copper preparations) or use them consecutively within a short period of time, as it will kill the active bacteria.
02
Create an appropriate environment
Soil temperature, humidity, and organic matter content can affect its colonization and effectiveness. Using it in combination with organic fertilizers will yield better results.
03
Pay attention to product activity
When purchasing, pay attention to the number of active bacteria and the expiration date of the product. Store it in a cool place.
Shelf life: 2 years.
