The use of chitosan oligosaccharide is helping soil microorganisms produce chitinase to interact with pathogenic bacteria, inhibit the growth of pathogenic bacteria, make susceptible plants produce systemic resistance, promote plant synthesis of phytoprotegerin, stimulate the synthesis and accumulation of plant lignin, and at the same time promote the activity of plant disease-resistant enzymes.
With the systemic resistance of plants, the vascular bundles of stem base had no lesion or lessened, the root system was developed, the plant was vigorous, the fresh weight of individual plants was increased, and the disease resistance was improved.
Eco-Friendly, Without Any Residues
Chitosan oligosaccharide is different from traditional pesticides. It does not directly affect harmful organisms but stimulates the immune responses of plants themselves(including stress resistance)to play an essential role in resisting stress, resisting diseases and insects, and increasing production. Soil microorganisms quickly degrade chitosan oligosaccharide into water and carbon dioxide, which are easily absorbed by the environment without residues.
The plant resistance components induced by Chitosan oligosaccharide are typical components of plants and are safe for human beings and livestock. It produced plant resistance components are natural components of plants, which are safe for humans and livestock. At the same time, the resistance of plants induced by Chitosan oligosaccharide has a broad spectrum and a long duration. Long-term or multiple inductions do not produce specific resistance in plants.
Up till now, no resistance to pathogens has been found. Therefore, the use of plant immune elicitor Chitosan oligosaccharide to induce plant immunity can make full use of plant defense ability and reduce the use of chemical pesticides, protect the environment, and meet the requirements of green plant protection and ecological civilization construction.
