Light Yellow Water Soluble Agricultural Chitosan Deacetylation 95%

Molecular Weight≤3000 Light Yellow Water Soluble Agricultural Chitosan Deacetylation 95%

General Information of Agricultural Chitosan

Agricultural Chitosan, also known as chitosan oligosaccharide and chitosan oligosaccharide, is an oligosaccharide product with a degree of polymerization between 2 and 20 obtained by degrading chitosan by a special biological enzyme technology, with a molecular weight of ≤3000Da.

It is a low molecular weight product with good water solubility, great functional effects and high biological activity. It is fully soluble in water, easy to absorb and utilized by organisms, and its effect is 14 times that of chitosan.

It is stable, safe, non-toxic, non-stimulant and easily deliquesce.

Benefits of Agricultural Chitosan

Chitosan-oligosaccharides alter soil flora and promote the growth of beneficial microorganisms. Chitosan-oligosaccharides can also induce disease resistance in plants, creating immunity and killing a variety of fungi, bacteria and viruses. It has good control effect on rice blast, rice blast, tomato late blight and other diseases, and can be developed as biopesticide, growth regulator and fertilizer.

The role and efficacy of chitosan oligosaccharides:

1. Improve the soil environment

This product is a nutrient source and health product for soil beneficial microorganisms, a good medium for soil beneficial microorganisms, and has a good recognition effect on soil microbial flora. It can promote the formation of soil aggregate structure, improve the physical and chemical properties of the soil, enhance the air permeability and water and fertilizer retention capacity, thereby providing a good soil micro-ecological environment for the root system, making various nutrients in the soil in an effective activation state, and improving the nutrients. Utilization efficiency, reducing the amount of chemical fertilizers. In addition, the molecular structure of the product contains amino groups, which can produce chelation with trace elements such as iron, copper, manganese, zinc, molybdenum, etc., so as to increase the effective state nutrients of trace elements in the fertilizer, and at the same time release the trace elements fixed by the soil. For crops to absorb and utilize, thereby improving fertilizer efficiency.

2. Induce plant disease resistance

The product acts as a stimulating factor that can effectively induce the production of plant resistance proteins chitinase, chitosanase and 1,3-glucanase, destroy fungal cell walls and inhibit fungal growth. At the same time, it can also induce the formation of plant lignin, promote the formation of secondary cell walls in plant vascular tissues, and form a physical barrier around the site of plant infection by lignification, thereby preventing or delaying the growth of pathogenic bacteria and spreading to surrounding normal tissues. , Enhance plant disease resistance. The active ingredients of the product can change the phenolic metabolism of plants, promote the accumulation of a large amount of bactericidal phenols at the point of plant infection, and enhance the plant's own disease resistance. The active ingredients of the product can induce plants to produce guaifen. When plants are attacked by pathogens, guaifen is deposited between cells, thereby separating the infected part from normal cells and forming a physical barrier.

3. Prevention and treatment of plant diseases

The active ingredient of the product is a derivative of chitin, so it can interact with the negatively charged side chains of biological macromolecules on the surface of pathogenic bacteria cells to form polymers, which can affect pathogenic bacteria and inhibit the growth of pathogenic bacteria. The active ingredients can also directly enter the nucleus of pathogenic bacteria, combine with DNA to inhibit the growth of pathogenic bacteria by affecting the synthesis of mRNA and protein. Therefore, it has a good effect of inducing disease resistance to fungal diseases whose cell wall is chitin.

4. Regulate plant growth

The active ingredients of the product can promote the early germination of plant seeds. Make the root system of crops develop, increase the number of root hairs, fibrous roots, and secondary roots greatly, enhance the plant's ability to absorb fertilizer and water, enhance drought resistance, lodging resistance, enhance immunity, and achieve the purpose of being strong and fruitful. It can fully activate the rhizosphere state, dissolve nutrient molecules, and quickly form a soil solution, so that nutrients such as nitrogen, phosphorus, and potassium can be fully and effectively absorbed by plants. It can grow roots and promote stems, shorten the stems, make them thick and vigorous, and is conducive to the maximum supply of nutrients to the fruit. The trace elements are easily absorbed by the fruit under the chelation of chitosan oligosaccharides, thereby increasing the content of protein and amino acids, fundamentally Improve quality. Improve crop quality Oligochitosan can increase crop yield, improve crop quality, restore natural flavor, storage and transportation resistance, and reduce pesticide residues.
