Core Overview
The extract from the rhizome of Polygonum cuspidatum utilizes the plant's own "chemical weapons" to combat pathogenic bacteria. Its core active components (such as polygonin, resveratrol) are the natural secondary metabolites that Polygonum uses to defend against bacterial invasion. It interferes with the life activities of pathogenic bacteria through multiple pathways and enhances the plant's own resistance.
Mechanism of Action
The mechanism of action is multi-targeted, mainly including:
Interfering with the cell membrane: The active components can affect the integrity and permeability of the cell membrane of pathogenic bacteria, causing the leakage of substances inside the cells.
Inhibiting mycelial growth and spore germination: Effectively inhibiting the elongation, branching, and germination of fungal hyphae of pathogenic fungi.
Inhibiting energy synthesis: Interfering with the energy metabolism processes such as respiration of pathogenic bacteria.
It can inhibit the activity of certain cell wall-degrading enzymes (such as glucanase, cellulase) secreted by pathogenic bacteria, which are important tools for pathogenic bacteria to invade plant tissues.
As an exogenous stimulator, it can activate the plant's defense system, increase the activity of defense-related enzymes (such as phenylalanine ammonia-lyase, peroxidase), promote the synthesis of phytohormones, and enable the plant to acquire systemic resistance.
Main Features
Plant-based, environmentally friendly
Derived from traditional medicinal plants, it is biodegradable and relatively safe for non-target organisms, meeting the requirements of green agriculture.
01
Broad spectrum of bacteriostatic effect
It has good control effects on various fungal and bacterial diseases, demonstrating broad-spectrum properties.
02
Both preventive and therapeutic functions
It can not only prevent the invasion of pathogens (protective effect), but also inhibit the expansion of pathogens at the initial stage of invasion (therapeutic effect).
03
Diverse mechanism of action
Multi-targeted action, less likely to induce pathogenic bacteria to develop resistance.
04
Certain promoting growth effect
Studies have shown that it can also promote the growth of crops to a certain extent and enhance the growth of plants.
05
Main Target Diseases to Be Controlled
Fungal diseases
Powdery mildew (for cucumbers, strawberries, grapes, melons, etc.), downy mildew (for cucumbers, grapes, cruciferous vegetables, etc.), gray mold (for strawberries, tomatoes, cucumbers, etc.), anthracnose (for peppers, watermelons, fruit trees, etc.), leaf spot diseases.
Bacterial diseases
Have a good control effect on citrus canker disease, angular leaf spot disease (such as bacterial angular leaf spot of cucumbers), etc.
Viral diseases
As an immune stimulant, it has a certain preventive and symptom-reducing effect on plant viral diseases.
Usage Notes
Prevention-oriented: It is recommended to apply before or during the early stage of disease occurrence to establish a protective barrier for the plants.
Even and thorough spraying: Due to its limited systemic absorption, it mainly relies on contact killing and local penetration. It is necessary to ensure that the pesticide solution covers the entire plant evenly, especially the back of the leaves.
Avoid mixing with alkaline substances: Mixing with strong alkaline pesticides such as Bordeaux mixture or sulfuric acid mixture may affect the efficacy.
Use immediately after preparation: It is recommended to use the prepared pesticide solution promptly and avoid long-term storage.
Pay attention to compatibility tests: If mixed with other pesticides or fertilizers, it is recommended to conduct a small-scale compatibility test first.
For aquatic organisms: Using according to the regulations is relatively safe for fish, but still, avoid polluting the water body.
Storage and transportation: Protect from light and moisture, store in a cool place; keep away from water sources.
Shelf life: 2 years.
