Details

Chitosan Oligosaccharide 10% liquid is a high-activity bioactive polymer derived from chitin deacetylation. It functions as a natural plant growth promoter, improving root vigor, stimulating nutrient uptake, and enhancing metabolic efficiency. Chitosan oligosaccharides also induce plant stress response mechanisms, helping crops tolerate drought, salinity, and other environmental stresses. Its high solubility and biocompatibility allow it to be applied directly or incorporated into liquid fertilizers, providing a safe, efficient, and sustainable solution for crop nutrition and quality improvement.

Field Application Cases

Wheat: After application, seedlings developed stronger and thicker roots with improved tillering. Leaf color deepened, photosynthesis efficiency increased, and overall plant vigor improved, supporting steady growth and higher yield potential.

Potato: After application, root development was significantly enhanced, with abundant fine roots and stronger root vitality, supporting better nutrient absorption and uniform tuber development.

Banana: After application, plants exhibited thicker stems, robust leaf growth, and improved root activity. Enhanced nutrient uptake promoted faster vegetative growth, stronger stress resistance, and better overall plant health.
