Chitosan Oligosaccharide (COS)
Ceres Organics is the Professional Supplier, Wholesaler, Export of Agriculture Chitosan Oligosaccharide Products for Sale in India. Your best choice to purchase bulk high-quality water-soluble chitosan oligosaccharide (COS) Powder & Liquid at a competitive price.
Chitosan Oligosaccharide Product is registered as a “plant inducer” in the Ministry of Agriculture and also known as a “sugar chain plant vaccine”. Its mission is to activate plants’ immunity ability to diseases & stress. And it’s suitable for all crops especially on tomato, pepper, coffee tree, tobacco, cannabis, etc.
Due to the high environmental risk of traditional chemical pesticides and legal restrictions on plant growth regulators. Biologicals for controlling plant diseases are highly recommended. COS is the high-efficiency solution with the features of non-toxic, bio-degradable.
For now, Chitosan oligosaccharide is widely used on
Seed Pretreatment – Disease resistance, strengthen seedlings
Soil Treatment – Prevent harmful pathogens and nematodes, improve soil condition, stimulate roots growth
Foliar Spraying – Induce crops’ immunity to stress & diseases
Specification of Ceres Chitosan Oligosaccharide
Ceres Chitosan is a chitosan oligosaccharide based product, its ingredient is COS (enzymatic hydrolysis process), which has outstanding water-solubility, high biological activity, and easily absorbed utilized by crops.

Features of Ceres Chitosan Oligosaccharide
Applications of Ceres Chitosan Oligosaccharide
1. Increase Seed Germination
After seed treatment, COS not only can improve seed vigour & germination rate but also can stimulate the seed’s immune & growth system to improve the disease-resistance & growth rate.
It has been proven that we apply on ryegrass seed, its germination index increased 33.5%, and the vitality index increased by 59.5%.

2. Increase Immunity Ability to Stress & Diseases
For Stress, chitosan oligosaccharide can induce plants’ general regulation of endogenous hormones.
For Diseases, COS can thicken the plant’s cell walls and instantly induce defense reactions to various kinds of viruses, fungus, and bacteria.
Especially on virus disease, chitosan oligosaccharide can prevent the occurrence of viral diseases and inhibit the virus from spreading to new leaves when virus outbreak.

3. Improve Soil Micro-environment
Control Harmful Nematodes Apply Chitosan oligosaccharide in the soil is sufficient to control nematodes. COS can stimulate the breeding of chitinolytic microbes to ruin the cuticle of nematodes eggs. Increase the Growth of Plant-Beneficial Rhizobacteria. After applying COS, beneficial microbes can quickly prosper, and their activity stimulated. Great help to build a healthy soil micro-environment.
4. Promote the growth of Stems, Leaves and Fruits
The use of chitosan oligosaccharide enhanced the photosynthesis of plants and increased their photosynthetic rate and efficiency. For example, the treatment of COS solution improved the chlorophyll and soluble protein content of ryegrass seedlings.
As a result, the plants generally showed sturdy stem nodes, enlarged leaves, bright color, vigorous growth and robustness. After using chitosan, the fruit set rate of eggplant vegetables and fruit trees were generally improved, and the weight of individual fruits increased.
How to use Ceres Chitosan Oligosaccharide
1. Optimal Use Concentration
Powder
Seed Treatment: 5g for 100-200Ibs seeds
Foliar Spray: 25-50g/ha per time, total 3-5 times
Water Flush: 500g per 1000L water per hectare
Liquid
Seed Treatment: 50ml for 100-200Ibs seeds
Foliar Spray: 200-500ml/ha per time, total 3-5 times
Water Flush: 2-4L per 1000L water per hectare
2. Optimum Use Time
During the critical period of crop growth, including seeds, seedling period, pre or post-planting, pre-flowering, expansion or grouting, etc.
Before or at the beginning of adversity, including cold damage, drought, waterlogging, and disease
3. Onset Time & Effect Duration
Onset time: <30 minutes
Valid period: 24-36 hours
Effect Duration: 7-9 days
4. Safety of using Chitosan Oligosaccharide
(1) Excessive use will delay the growth of crops in a short period of time and will recover in a few days without causing reduced yield and irreversible damage to the crops;
(2) Destructive tests on apples show that 5-10 times excess use is still safe for crops.
