chitosan oligosaccharide

                                                                   Specification

                                                                    Functions

For Agriculture Application

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 

For Human Beings

1. Anti-tumor, Anti-oxidation and Anti-radiation

2. immune regulation, intestinal regulation and endocrine regulation

3. eliminate excess cholesterol, heavy metals and toxins

4. Lowering Blood Glucose, Lowering Blood Pressure and Lowering Blood Lipids

For Feed Additive

1. Promote the proliferation of beneficial bacteria in animal intestinal tract

The vast majority of animals have no enzyme for digesting chitosan oligosaccharide in the digestive tract, chitosan oligosaccharide can completely reach the hindgut, and most of the chitooligosaccharides are selectively utilized by beneficial bacteria in the intestinal tract, thus promoting the mass reproduction of beneficial bacteria; Neutral bacteria and harmful bacteria (Escherichia coli, Salmonella, etc.) cannot utilize chitosan oligosaccharide, and will be inhibited by chitosan oligosaccharide, thus playing the role of beneficial bacteria proliferation factor and improving the gastrointestinal health of animals.

2. Adsorbing and removing intestinal pathogenic bacteria

The cell surface or villi of pathogenic bacteria (Escherichia coli, Salmonella, etc.) have protein-like structures, called Lectins, which can combine with receptors on the cell surface of intestinal inner wall to adhere to intestinal epithelium for reproduction. However, the structure of the receptor on the cell surface of the intestinal inner wall is the carbohydrate structure with short chain branches. Therefore, chitosan oligosaccharide will competitively combine with the Lectins on the cell surface of pathogenic bacteria to prevent the adhesion of pathogenic bacteria on the intestinal epithelium, so as to obtain no nutrients and lose pathogenicity.

3.Promoting the growth of animals

Improve the structure of animal intestinal mucosa, improve the function of digestive organs, increase the villus height and crypt depth of jejunum and ileum, thus facilitating the absorption of nutrients; Promote the absorption of calcium, phosphorus and vitamins, increase daily gain and feed conversion rate, and improve meat quality.

4. Improving animal immunity

Chitosan Oligosaccharide can improve the specific and non-specific immune functions of the body by stimulating the activity of immune cells and promoting the secretion of immune factors, enhance the disease resistance of the body, alleviate the poor prognosis of sick livestock and poultry,and reduce the death rate of animals.

5. Protecting Animal Organs

COS(chitosan oligosaccharide)have strong adsorbability, It can adsorb harmful heavy metals and other antibiotics in vivo and discharge them out of the body, thus reducing the damage of antibiotics to liver. Also, it can stimulate the absorption of trace elements by liver, kidney, spleen and stomach, improve the index of thymus, spleen and other organs, and protect the healthy growth of livestock and poultry.

6. Substitute or partially substitute antibiotics

Compared with antibiotics, it has the advantages of no drug resistance, no drug residue, no destruction or killing of beneficial bacteria.

                                                                  Application&Dosage

For Agriculture Dosage

- New biological fertilizers (plant growth regulator, foliar fertilizer, flushing fertilizer, seed coating agent) and biological pesticides,etc.

1. Seed treatment

100ppm seed soaking for 12-24 hours, or 500ppm seed dressing or spraying

2 Foliar spray

50-100ppm (manual or mechanical sprayer), the flying defense concentration needs to be increased

3 Underground fertilization

225-375 grams Chitooligosaccharides per hectare

Best use time

1. During the critical period of crop growth, including seed, seedling period, before and after planting, before flowering, swelling period, and filling period

2. Before the adversity, freezing damage, drought, waterlogging, and disease

Onset of Chitooligosaccharides:

Effective period 24-36 hours

The validity period is 7-9 days.

For Feed dosage

----  Feed for cattle, pig, and sheep  we recommend 200 gram COS(chitosan oligosaccharide) add to 1 ton feed.

 ---- Feed for poultry and fish,  we recommend 100 gram  COS（chitosan oligosaccharide） add to 1 ton feed.
