Water Soluble Chitosan Oligosaccharide 95% Deacetylation Agricultural Chitosan Powder
General Information of Agricultural Chitosan
Agricultural Chitosan is made from raw materials such as crab shells and shrimp skins. Chitosan is extracted and then degraded using bio-enzymatic technology. Its degree of polymerization ranges from 2 to 20, and it is bonded by β-1 and β-4 bonds. It has a low molecular weight, good water solubility, high activity, and is rapidly absorbed by plants, possessing unique biological functions.
This low molecular weight product offers excellent water solubility, significant functional benefits, and high biological activity. It is completely soluble in water and easily absorbed by organisms, with a potency 14 times that of chitosan.
It is stable, safe, non-toxic, non-stimulant and easily deliquesce.

Benefits of Agricultural Chitosan
1. Improving Crop Disease Resistance
Treating plants with chitin and its derivatives before infection can induce sensitization, resulting in higher protection against re-infection with pests and diseases than normal plants. Chitin is toxic to certain fungi, bacteria, viruses, and pests, and it induces plant defenses to activate.
Chitosan oligosaccharides cannot directly inactivate viruses, but they significantly inhibit their replication and long-distance movement within plants. They also have a limited effect on plant viral diseases. When applied before a viral outbreak occurs, they can prevent the onset of viral diseases and induce resistance to viral proliferation and long-distance movement in plants.
2. Activating the plant's innate immune system
Chitin, a major component of the cell wall of fungal pathogens, can stimulate plant immune responses. Plant cell membranes contain a variety of pattern recognition receptors that trigger innate immune responses by recognizing common and conserved molecular motifs (i.e., pathogen-associated molecular patterns) on pathogens. Chitin is a key component of plant cell membranes. Chitooligosaccharides can bind to receptors on plant cells, stimulating the production of resistance signaling molecules. Through signal transduction, they stimulate the expression of resistance genes and the production of resistance substances, thereby achieving disease control.
3. Improving Crop Stress Resistance
During agricultural production, drastic changes in the external environment can cause significant and irreversible damage to plants. Cold weather often harms crops grown in greenhouses and in open fields in early spring. When weather conditions are abnormal, crops such as citrus and grapes in the south can also suffer frost damage or freezing injuries, resulting in weak seedlings, wilting leaves, flower and fruit drop, and fruit deformities. Low ground temperatures can also damage roots, reduce absorption capacity, and lower photosynthetic efficiency, directly impacting crop yield and quality. For example, low temperatures can easily reduce plant cell membrane fluidity and lead to peroxidation, damaging plant cells. Chitosan oligosaccharides can increase the content of cold-resistant substances such as soluble protein and soluble sugar, reduce membrane lipid peroxidation, increase membrane permeability, maintain high photosynthetic activity in crops, and effectively protect against the damage caused by low temperatures.
4.Improving rhizosphere microbial populations and inhibiting nematodes
Many organisms in the soil (such as plants, bacteria, and fungi) produce chitinase, an enzyme that breaks down chitinous tissue in fungi and insects and destroys its structure. Adding chitosan to soil promotes the growth and activity of microorganisms, leading these microorganisms to produce more chitinase, antibiotics, and toxins. These microorganisms can compete directly with pests for nutrients, parasitize them, or activate plant defense systems. This improves control effectiveness against chitinous pests. Chitin oligosaccharides have a secondary nematode inhibitory effect. They can induce plant roots to secrete chitin hydrolases, which break down the chitin in the cell walls of nematode eggs. Experiments have shown that chitin oligosaccharides can repair damaged roots and promote rooting. The effects begin within 1-2 days, with new roots visible after 5-7 days. They mitigate the damage caused by thiazolylpyridoxine and exhibit a synergistic effect with thiazolylpyridoxine.
5. Promotes Rooting in Crops
Oligosaccharides, when absorbed by plants, induce the production of auxins such as indoleacetic acid and gibberellins, stimulating root development. Seed dressing with sugar water can promote early germination. This results in more numerous and longer capillary roots in the seedling stage. Potatoes have a strong root absorption capacity in the middle and late stages of their growth, enabling them to better utilize fertilizer and water, laying the foundation for drought resistance and increased yield. Cotton seed coatings treated with a 0.05-0.2% concentration for 30 minutes can promote seed germination, improve germination rates, and increase the number of bolls per plant.
