In the era of green and sustainable agriculture, natural and safe bio-based agricultural inputs are increasingly essential. Among them, chitosan oligosaccharide (COS)—a bioactive compound derived from the degradation of chitin—has attracted wide attention due to its biodegradability, zero residue, and multifunctional agricultural benefits.
Also known in agriculture as oligoglucosamine or amino-oligosaccharide, this innovative material offers a unique combination of plant protection, soil improvement, growth promotion, and crop quality enhancement. At Wellyou Tech, we provide high-quality chitosan oligosaccharide solutions tailored to modern farming needs, supporting growers in building more resilient and eco-friendly production systems.
Key Agricultural Applications of Chitosan Oligosaccharide
1. Plant Protection
COS and its derivatives function as natural biopesticides with both nutritional and protective properties. They demonstrate antibacterial, antifungal, and antiviral effects, helping farmers reduce dependence on synthetic pesticides. By enhancing crop resistance, chitosan oligosaccharide supports the prevention and control of diseases in fruit trees, vegetables, tobacco, grains, and cotton. This dual role aligns perfectly with the global trend toward residue-free and eco-friendly crop protection.
2. Soil Improvement
As a soil conditioner, COS improves soil structure and fertility. It enhances water retention, aeration, and microbial balance, creating a favorable environment for beneficial microorganisms. The result is healthier soils that support robust root systems, stronger plant growth, and ultimately higher yields.
3. Plant Growth Promotion
COS acts as a plant growth promoter, stimulating root development, improving photosynthetic efficiency, and enhancing nutrient uptake. Crops treated with chitosan oligosaccharide often show better stress tolerance, increased adaptability, and improved growth performance, which translates into higher yield and superior crop quality.
4. Enhanced Plant Immunity
One of the most notable advantages of COS is its ability to activate plant immune responses. By inducing the production of defense proteins and protective compounds, it boosts natural resistance against environmental stresses and pathogens. This immune-stimulating effect reduces the incidence of crop diseases and supports long-term plant health.
5. Organic Fertilizer Additive of Chitosan Oligosaccharide
COS is also widely used as an organic fertilizer enhancer. When incorporated into organic fertilizers, it improves nutrient availability, enriches soil quality, and reduces the reliance on chemical fertilizers. This makes it an ideal choice for organic and sustainable farming systems seeking balanced plant nutrition and environmental protection.
