Product Introduction
As a high-efficiency functional water-soluble fertilizer, Chitosan Oligosaccharide Water Soluble Fertilizer is a natural bio-stimulant derived from marine chitin enzymolysis. It features ultra-low molecular weight and full water solubility, uniquely activating crop immune systems and optimizing soil micro-ecology. It improves nutrient absorption efficiency, enhances crop stress resistance, and suppresses soil-borne pathogen proliferation. Serving as a core functional raw material for agricultural foliar fertilizers, root irrigation fertilizers and functional compound fertilizers, it effectively solves continuous cropping obstacles, improves crop quality and promotes stable yield increase in modern green planting.
Note: Chitosan oligosaccharide has both fertilizer registration (as functional water-soluble fertilizer) and pesticide registration (as plant immune elicitor) in China. Registration category depends on the specific product positioning.

Health Benefits & Values
Crop Immune Activation & Disease Resistanc
Acts as a plant immune elicitor, activating systemic acquired resistance (SAR) and pathogen-triggered immunity (PTI) pathways to enhance crop self-defense against fungal, bacterial, and viral pathogens.
Root Promotion & Nutrient Utilization Improvement
Stimulates root cell division and root hair growth, enhancing crop absorption and utilization of water and soil nutrients.
Soil Micro-Ecological Optimization
Promotes beneficial microbial reproduction, suppresses harmful bacteria growth, and alleviates continuous cropping soil degradation.
Multi-Stress Resistance Enhancement
Improves crop tolerance against drought, low temperature and saline-alkali stress, stabilizing growth under adverse field conditions.
Quality & Yield Promotion
Regulates crop physiological metabolism, optimizing fruit coloring, sweetness and uniformity to upgrade agricultural product quality.
Core Value in Formulation Development

FAQ (Technical Q&A)
Q1: How does this product differ from conventional fertilizers in mode of action?
A: Unlike conventional fertilizers that directly supply nutrients, chitosan oligosaccharide is a functional bio-stimulant that activates the plant's immune system (SAR and PTI pathways) and optimizes soil micro-ecology. It enhances nutrient absorption and stress resistance indirectly by stimulating the plant's own defense and growth mechanisms.
Q2: What is the optimal application rate for foliar spray and root irrigation?
A: For foliar spray, typical dilution is 400–600 times, applied every 7–10 days. For root irrigation, dilute 600–800 times. For water-soluble fertilizer blending, add 1–2 kg per ton of fertilizer. Adjust based on crop type and growth stage.
Q3: Can it be tank-mixed with pesticides?
A: It is compatible with most neutral and acidic pesticides and fertilizers. Avoid mixing with strongly alkaline products. When mixed with copper-based fungicides, a small-scale jar test is recommended to check for precipitation before large-volume mixing.
Q4: How does it alleviate continuous cropping obstacles?
A: It promotes beneficial soil microbial reproduction (such as Bacillus and Trichoderma), suppresses harmful pathogen accumulation, and improves soil aggregate structure. This helps restore soil microbial balance and reduce seedling death and root disease in continuous cropping fields.
Q5: Is this product approved for organic agriculture?
A: Chitosan oligosaccharide is a natural marine-derived oligosaccharide, fully biodegradable and residue-free. It is accepted in most organic and green planting schemes. Check local organic certification requirements for specific approval status.
Q6: What crops have shown the best response to Chitosan Oligosaccharide application?
A: Registered uses and field trials show strong responses on vegetables (cucumber, tomato, pepper), fruits (grape, strawberry), tea, and traditional Chinese medicinal materials. It is particularly effective for seedling root strengthening and continuous cropping soil improvement.
Q7: How should this product be stored to maintain biological activity?
A: Store sealed in a cool, dry, ventilated warehouse away from moisture, high temperature, and strong alkaline substances. Shelf life is typically 2 years under proper storage conditions.
Q8: Does Chitosan Oligosaccharide have any phytotoxicity risk?
A: No. It is naturally derived with low irritation and high safety. It is suitable for all field crops, fruits, and vegetables without phytotoxicity risk at standard dosage.
Q9: What is the difference between Chitosan and Chitosan Oligosaccharide?
A: Chitosan is a high-molecular-weight polymer with poor water solubility. Chitosan oligosaccharide is a low-molecular-weight oligosaccharide (DP 2–20, MW ≤3200 Da) with 100% water solubility, higher crop absorption rate, and stronger biological activity. Its activity is approximately 14 times that of chitosan.
Q10: Can Chitosan Oligosaccharide Water Soluble Fertilizer be used in drip irrigation systems?
A: Yes. It is 100% water-soluble with no residue and fully compatible with drip irrigation, sprinkler irrigation, and fertigation systems. Flush the system with clean water after application to prevent any accumulation.
