Chitooligosaccharide could be considered as water-soluble chitosan oligomer which is made from depolymerizing chitosan by enzyme hydrolysis. And its average molecular weight (≤3kDa) is muc lower than chitosan's (≥100KDa). The low molecular weight benefits prominent water solubility and bioactivities which attracte the interest of many researchers and companies to utilize chitooligosaccharide for agricultural applications.


COS (short for chitooligosaccharide) is a useful tool for the Integrated Pest Management (IPM). COS has shown to be effective elicitor of Induced Systemic Resistance (ISR) in plant which actives plants' natural defenses to boost plant vigor, improve plant health and yield parameters. 


English Name: Chitosan oligosaccharide, Chitooligosaccharide, Chitosan Oligomers, Chitooligomer, Oligochitosan, 

Chitosan Oligosaccharin, Chitosan Oligo Saccharins, COS.

Origin From: Crab shells
Molecular Formula: (C6H11NO4)n(n=2~20)
Structural Formula:

chitooligosaccharide             chitosan oligosaccharide



    - Low Dosage (Optimal concentration ranging 50-100ppm); 

    - Non-toxic & Biological degradable - Free from chemical residues;

    - Plant elicitor; 

    - High efficiency for crops, vegetables, turf, fruits & flowers. 



Benefits for Plants:

1.  Activate Plant Defense Responses against Fungal, Bacterial, Vivus Diseases & Environment Stress

     - Activate and induce plant immune reactions & plant self-defence machinery to increase the resistance ability under environment stress(heat, cold, drought, etc)

     - Activate plants' defense response in the treated plants and stimulate additional biochemical pathways that strengthen the plant structure and act against the fungal, bacterial and vivus diesases.


2.  Promote Plant Growth and Enhance Yield Potential

      - Promote plant seed germination and seeling growth 
      - Promote plant root, stalk and leaf growth  
      - Promote plant fruit growth, and improve yield & profits  
      - Mineral absorption accelerant 


3.  Improve Soil Structure

     - Prevente and Restrain nematodes 
     - Activating the growth of useful microbes, suppressing harmful microbes 
     - Restoration of soil ecology  



     - A perfect choice for Biostimulants formulation; 

     - Active ingredient of Biofertilizers, Organic fertilizers, Plant Growth Regulators, Foliar Spray Fertilizers, Fertigation Feritilizers;

    - Active ingredient of Organic pesticides, Biopesticides & Biofungicides, Plant Vaccine, Chitosan Oligo Saccharins;

     - Active ingredient of Bionematocides, 

     - Active ingredient of hydroponics nutrient solutions.
