Product Description
Chitosan Oligosaccharide is made from chitosan by enzymatic hydrolysis to make chitosan oligosaccharide (COS), which has good water solubility, high biological activity, easy to be absorbed by the crops and effectively utilized. Chitosan Oligosaccharide is a natural “plant inducer”, which can activate disease resistance and stress tolerance by enhancing plant immunity and is effective in many crops. Chitosan Oligosaccharide is a natural “plant inducer”, which can activate disease and stress resistance by enhancing plant immunity, and is very effective for various of crops.
Applications
Seed treatment. Improves disease resistance and seedling strength.
Soil application. Controls pathogens and nematodes, improves soil and stimulates root growth.
Foliar spray. Induces plant immunity to biotic and abiotic stresses.
Key Features
Molecular weight is around 800-2000 Dalton, High activity.
Finely dried powder with high flowability.
Excellent compatibility for formulation basement.
Use an eco-friendly enzymatic hydrolysis technology.
Benefits
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.
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.
Balance soil microbial environment. It can control harmful nematodes, and increases growth and activity of plant-beneficial rhizobacteria. The dual effects of nematode control through egg degradation and increased proliferation of beneficial rhizosphere bacteria make COS a valuable soil treatment.
Maintain the whole growth of plants. Chitosan oligosaccharide boosts photosynthesis, increasing the photosynthetic rate and efficiency of plants. Plants exhibited sturdier stem nodes, larger leaves, brighter color, vigorous growth, and robustness after COS application.
Shelf Life
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.
Remark
No chemical residue.
