Chitosan Oligosaccharide (COS) is a natural, water-soluble biostimulant widely used in modern agriculture. As a leading chitosan oligosaccharide supplier in China, we provide high-quality COS designed for plant growth promotion, disease resistance, and yield enhancement. Our chitosan oligosaccharide agriculture grade is ideal for use in fertilizers, foliar sprays, and irrigation systems, supporting the transition to eco-friendly and sustainable farming.
What is Chitosan Oligosaccharide?
Chitosan Oligosaccharide is derived from natural chitin through enzymatic hydrolysis, resulting in low molecular weight, fully water-soluble oligosaccharides with high biological activity.
Key Features:
- 100% water soluble
- Low molecular weight (1000–3000 Da)
- High bioactivity
- Eco-friendly & biodegradable
- Compatible with most fertilizers
Key Benefits of Chitosan Oligosaccharide in Agriculture
