Chitosan Oligosaccharide for Plants - Dora Sailor
General Information
Dora Sailor is the brand name for the chitosan oligosaccharide for plant. It is produced through enzymatic hydrolysis of chitosan to make chitosan oligosaccharides (COS). Dora Sailor COS features excellent water solubility, high bioactivity, and easy crop absorption for effective utilization.
Dora Agritech is the leading supplier and exporter of agriculture Chitosan Oligosaccharide products for plants in China. Purchase high-quality, water-soluble Chitosan Oligosaccharide (COS) at competitive prices.
Our COS is recognized as a natural "plant inducer" that activates disease and stress resistance by boosting plant immunity. It works well on all crops, especially tomatoes, peppers, coffee, tobacco, and cannabis.
Due to environmental risks of chemicals and restrictions on growth regulators, biological solutions like non-toxic, biodegradable COS are ideal.
Chitosan Oligosaccharide for Plants has diverse uses:
1. Seed Treatment - Improves disease resistance and seedling strength.
2. Soil Application - Controls pathogens and nematodes, enhances soil, and stimulates root growth.
3. Foliar Spray - Induces plant immunity against biotic and abiotic stresses.
Key Features
1. Molecular weight is around 800-2000 Dalton, High activity.
2. Finely dried powder with high flowability.
3. Excellent compatibility for formulation basement.
4. Use an eco-friendly enzymatic hydrolysis technology.
Benefits
1. Promote seed germination
Treating seeds with chitosan oligosaccharide (COS) boosts vigor, germination rate, disease resistance, and growth by stimulating the plant's immune and developmental systems. Application on ryegrass seeds increased the germination index by 33.5% and vitality index by 59.5%, demonstrating COS's potential to improve seed performance.
2. Improve plant’s immunity to diseases and climate stresses
Chitosan oligosaccharide enhances plants' stress tolerance by modulating endogenous hormones for improved physiological adaptation. This increases water retention, cold/drought resistance, and recovery from damage.
For disease resistance, COS reinforces cell walls and rapidly triggers defense reactions against viruses, fungi, and bacteria. It is especially effective against viral diseases by preventing initial infection and containing the virus to already affected leaves.
COS improves abiotic stress tolerance through hormonal regulation while also inducing biotic disease resistance via physical and biochemical mechanisms. This multifaceted mode of action makes it a versatile tool for integrated crop protection.
3. Balance soil microbial environment
1) Control harmful nematodes: Chitosan oligosaccharide controls harmful nematodes when applied to soil by promoting chitinolytic microbes that destroy nematode egg cuticles.
2) Build PGPRs system: COS also increases growth and activity of plant-beneficial rhizobacteria, rapidly enhancing populations of these helpful microbes to build a healthy soil microenvironment.
The dual effects of nematode control through egg degradation and increased proliferation of beneficial rhizosphere bacteria make COS a valuable soil treatment.
4. Maintain the whole growth of plants
Chitosan oligosaccharide boosts photosynthesis, increasing the photosynthetic rate and efficiency of plants. Treatment with COS enhanced chlorophyll and soluble protein levels in ryegrass seedlings.
Plants exhibited sturdier stem nodes, larger leaves, brighter color, vigorous growth, and robustness after COS application. Fruit set rates and individual fruit weights of eggplants and fruit trees also improved.

FAQ
1. Can Chitosan Oligosaccharide for Plants be mixed in low pH solutions ranging from 3-4.5?
Yes, Dora Chitosan Oligosaccharide for Plants is obtained by lactic acid fermentation, yielding a weakly acidic product that is stable in mildly acidic solutions with pH 3-4.5.
2. Are there ingredients Chitosan Oligosaccharide for Plants should not be mixed with?
It is not recommended to mix Chitosan Oligosaccharide for Plants with highly alkaline chemical pesticides. To formulate, first add water, then COS, mixing thoroughly. Add other ingredients sequentially with even mixing.
3. What is the shelf life of Chitosan Oligosaccharide once liquified with water or other carriers?
The standard shelf life of Chitosan Oligosaccharide for Plants diluted in water or other aqueous carriers is 2 years. Adding a preservative can extend stability of the formulation.
4. How to mix Chitosan Oligosaccharide for Plants with ningnanmycin?
Use a 1:9 ratio of Chitosan Oligosaccharide for Plants to 8-10% ningnanmycin stock solution. Dilute this mixture 2000 times with water for application.
