Agricultural chitosan and nematode control

The Mechanism of Chitosan Oligosaccharides in Preventing and Controlling Nematodes

(1) Chitosan oligosaccharides can induce crops to produce a chitinase that breaks down and absorbs chitosan oligosaccharides from nematodes and eggshells, causing the dissolution of nematode body walls and eggshells, leading to the death of nematodes and eggs. Early and frequent use of chitosan oligosaccharides on crops can induce the quantity of chitinase to remain at a high level for a long time, achieving the goal of preventing nematodes.

⑵ After application of chitosan oligosaccharides to soil, a large number of beneficial bacterial communities such as actinomycetes can be cultivated in a short period of time. These beneficial bacterial communities secrete a large amount of antibiotic substances and chitinase (chitinase can decompose and destroy nematode egg walls and body walls), which can directly inhibit nematodes and insect eggs, while inhibiting harmful bacterial communities such as Aspergillus, Phytophthora, Rhizoctonia, Fusarium, etc., thereby reducing the complex infection of harmful bacteria caused by nematode damage and alleviating "dead plants".

Chitosan oligosaccharides have a strong rooting and root nourishing effect, promoting the division of root cells, rapidly increasing capillary roots, reducing the occurrence of rotting roots, dead roots, and rotten roots, and promoting root development. Therefore, when crops suffer from nematode damage during their growth or fruiting period, root irrigation treatment can restore their vitality and maintain normal growth status, thus minimizing the losses caused by nematode damage.

According to measurements, the use of oligosaccharides fertilizer can increase fiber degrading bacteria and autotrophic nitrogen fixing bacteria in the soil by nearly 10 times, and increase the number of actinomycetes by 30 times.
