PH7-9 Agricultural Chitosan White Color Powder Application Of Chitosan Polymer Agriculture
General Information of Agricultural Chitosan
Chitosan polymer is a linear polysaccharide composed of randomly distributed beta -(1→4)- linked D-glucosamine (deacetylated units) and n-acetyl-d-glucosamine (acetylated units). It is made by treating the chitin shells of shrimp and other crustaceans with an alkaline substance, such as sodium hydroxide.
Chitosan polymer has many commercial uses. It can be used in agriculture as a seed treatment and biocide to help plants fight fungal infections

Raw Material of Agricultural Chitosan
Chitosan Polymer related products mainly derived from the shell of crab and shrimp skin. it is typically nature based and can be regenerated.
Benefits of Agricultural Chitosan
1. The role of chitosan
① Chitosan can regulate crops for plants, such as increasing the germination rate of crops, plant height, increasing single plant weight, root length, leaf area, etc. Increase crop output, such as increasing the output of wheat, rice, corn, soybean and other food crops; it can increase the output of cucumber, cabbage, tomato, potato and other vegetables.
② Improve the quality of crops
Chitosan can significantly increase the protein content of crops, in addition, it can increase the content of vitamin C, total soluble sugar, and reduce the content of crude fiber. It can be seen that the use of chitosan can achieve the purpose of improving the nutritional quality of crops, making them more nutritious and of higher commodity value.
③ Inhibit the growth of pathogenic bacteria, improve the antibacterial activity of crops and the ability to resist pests and diseases
Studies have shown that between plant pathogenic bacteria and parasitic plants, chitosan can hinder the spore germination and growth of plant pathogenic bacteria, and induce the protective function of pathogen infection. Therefore, chitosan can inhibit the growth of pathogenic bacteria.
In addition, plants contain chitinase and chitosanase, although chitin and chitosan do not exist in plants, once the plant's chitosanase comes into contact with chitosan from the outside, it will make the plant's Chitosanase is activated, and at the same time enables plants to develop the ability to defend against pests and diseases, preventing pathogenic bacteria and pests from invading plant tissues, thereby enhancing the ability of plants to defend against pests and diseases.
Compared with other plant regulators, chitosan has natural, non-toxic, tasteless, good environmental compatibility, high activity, easy to degrade, etc.
Advantages, therefore, have great prospects for development in agriculture.
Chitosan Mode of Action:
① Chitosan is mixed with crop seeds, or used as a coating agent for soaking seeds;
② As a spray on the foliage of crops;
③ As a bacteriostatic agent to inhibit pathogenic bacteria and pests;
④ As a soil improver or fertilizer additive;
⑤ Preservatives for food or traditional Chinese medicine.
Application of Agricultural Chitosan
Main points of using chitosan in agriculture
① The role of chitosan in agriculture has an important relationship with the concentration of chitosan solution.
For different purposes, different crops, and different application methods, the concentration of dilution is also different. If the concentration is too large or too small, the effect of chitosan will be affected.
② Different molecular weights and different derivatives of chitosan have obviously different application effects in agriculture. For example, chitooligosaccharides have more obvious effects on inhibiting pathogenic bacteria, improving antibacterial activity and resisting pests and diseases.
③The safety of chitosan
Chitosan is a pure natural animal polysaccharide obtained by processing the chitin of shrimp and crab. It is non-toxic and harmless, and will not cause any pollution to crops, humans, animals and the environment. Therefore, chitosan is used in agriculture It is a very safe biotechnology. The grains, vegetables and other foods treated with chitosan are unlikely to have any residues of harmful chemical substances such as pesticides.
During formula making chitosan polymer had showed exact performance.
