Application
The application principle of astragalus polysaccharides in plants mainly lies in stimulating the systemic disease resistance of plants, while also having certain growth regulatory effects.
Core Function: Antagonist (Plant Immune Activator)
Mechanism: When astragalus polysaccharides are absorbed by plants, they are recognized by plant cells as an "excitator", thereby activating the plant's own defense system and triggering a series of defense responses, such as:
Increase the thickness of the cell wall.
Generate antibacterial substances such as phytohormones.
Activate defense signaling pathways related to salicylic acid and jasmonic acid.
Effect: It enables plants to be in a "highly alert" state before the invasion of pathogens (fungi, bacteria, viruses), thereby effectively preventing the occurrence of diseases.
Specific Applications and Effects
Prevention and treatment of viral diseases
This is the most prominent and effective application of astragalus polysaccharides in plants. It has a significant inhibitory and alleviating effect on viral diseases such as leaf mottling and fern leaf virus in crops like tomatoes, peppers, tobacco, and melons. It is usually classified as a "plant growth promoter" or "biological pesticide" along with amino oligosaccharins and mushroom polysaccharides.
Enhancing disease resistance
It also has a certain preventive effect against fungal diseases such as powdery mildew, downy mildew, and leaf spot. It does not directly kill the pathogens, but instead enhances the immunity of the crops to resist infection.
Promote growth and improve quality
Some research and practice have shown that astragalus polysaccharides can stimulate the development of crop root systems, enhance photosynthesis in leaves, thereby making the plants stronger, increasing yield and improving the quality of agricultural products.
Mitigating pesticide damage, enhancing resilience
When crops suffer from mild pesticide damage or encounter adverse conditions (such as low temperature, drought), the use of astragalus polysaccharides can help the plants recover their growth and enhance their resilience.
Product form: Primarily registered as a biological pesticide (such as 0.5% and 1% water solutions of astragalus polysaccharides), used for controlling viral diseases.
