1. It can change the soil microflora, promote the growth of beneficial microorganisms and inhibit some plant pathogenic bacteria. Chitosan oligosaccharide can stimulate plant growth and increase the yield of crops, fruits and vegetables. ?
2. Chitosan oligosaccharide can induce plant disease resistance, produce immunity and killing effects on a variety of fungi, bacteria and viruses, and can effectively control wheat mosaic disease, cotton verticillium wilt and rice blast disease. , tomato blight and other diseases have a good control effect.
3. Chitosan oligosaccharide has a certain degree of direct inhibitory effect on various plant pathogenic bacteria. The application of chitosan oligosaccharide has the characteristics of trace amount (PPM level), high efficiency, low cost, and no pollution, which is of great significance to the sustainable development of my country's agriculture.

Practical applications of aminooligosaccharides:
Aminooligosaccharides have broad-spectrum antibacterial properties. Research shows that aminooligosaccharides induce crops to produce a variety of resistance substances, which are effective in the prevention and control of diseases caused by viruses, fungi, bacteria, etc. What is particularly important is that the prevention and control of viral diseases was often a difficult problem for plant protection in the past, but the control effect of aminooligosaccharide pesticides is very satisfactory. The application of aminooligosaccharides can prevent and directly control crop diseases such as anthracnose, blight, wilt, and root rot.
Research has found that crops that frequently use amino-oligosaccharides are less likely to suffer from insect pests. Amino-oligosaccharide pesticides are most effective when the insects have just hatched into larvae. Amino-oligosaccharides have obvious contact killing effects on various aphids, and aphids will die 4 to 12 hours after contact with the drug.
Aminooligosaccharides can be used as drug sustained-release agents to extend drug action time and reduce drug dosage. Therefore, chitin and its derivatives can be used as seed treatment agents for grain and vegetable crops to stimulate early germination of seeds, promote crop growth, improve disease resistance, and thereby increase crop yields.
After aminooligosaccharide fertilizer enters the soil, it can promote the proliferation of beneficial bacteria such as nitrogen-fixing bacteria, fiber-decomposing bacteria, lactic acid bacteria, and actinomycetes; and inhibit the growth of harmful bacteria such as mold and filamentous bacteria. It is converted into high-quality organic fertilizer for crops to absorb and utilize. At the same time, it can effectively improve the soil aggregate structure, effectively improve the soil, and improve the living environment of crops. It is a multi-functional soil conditioner.
Aminooligosaccharides are used on the surface of fruits to block the invasion of pathogens. Moreover, this film has good moisturizing effect and selective breathability. Therefore, chitin can be the best preservative for fruits and vegetables. raw material.
Among the various resistance substances produced by crops induced by aminooligosaccharides, some have the effect of preventing, reducing or repairing stress damage to plant cells. Therefore, the application of chitin can improve the cold resistance and resistance of crops. High temperature, drought and flood resistance, salt-alkali resistance, fertilizer damage resistance, air damage resistance, nutritional imbalance resistance and other stress resistance.
