Chitosan oligosaccharides are widely used as natural fungicides in the field of agriculture. Prevent and fight disease, this mainly includes induction of disease resistance, broad-spectrum antibacterial activity, and antiviral activity.
It has antibacterial effect, can inhibit the growth and reproduction of microorganisms, and has a good antibacterial effect on some common plant pathogenic bacteria. it can improve plant immunity, induce plant defense responses, and enhance plant resistance to pathogenic bacteria.
Chitosan Oligosaccharide can combine with anions on the surface of microorganisms to destroy the structure and function of microbial cell membranes, resulting in the death of microorganisms.
