Agricultural Biostimulants

Chitosan Oligosaccharide (COS)

Source

Derived from shrimp and crab shells through a multi-step process:

• Decalcification
• Deproteinization
• Deacetylation
• Enzymatic hydrolysis

Key Features

• High Purity: >93% glucosamine content (highest standard in China)
• Optimal Polymerization: DP range of 2-8 (DP 4-6 shows highest bioactivity)
• No Monomeric Glucosamine: Ensures superior quality and performance
• Dual Registration: Approved as both agricultural pesticide and biostimulant in China

Agricultural Applications

• Plant Growth Promotion: Enhances seed germination and root development
• Fruit Quality Improvement: Increases sweetness, color, and luster
• Disease Control: Suppresses soil-borne diseases and plant viruses
• Stress Relief: Alleviates pesticide phytotoxicity
• Synergistic Effects: Works effectively with other biostimulants

Alginate Oligosaccharides (AOS)

Source

Low-MW oligosaccharides derived from enzymatic hydrolysis of alginate

• Alginate is the most abundant polysaccharide in brown algae
• In mature brown algae cells, the ratio of alginate, fucoidan, and cellulose is 3:1:1

Key Features

• Bioactive Structure: Contains unsaturated double bonds at non-reducing ends (critical for activity)
• Natural Composition: Polymer of mannuronic and guluronic acids (M/G blocks)
• Enzymatic Advantage: Chemically-derived AOS show negligible biological activity

Agricultural Applications

• Root & Growth Stimulation: Promotes auxin synthesis
• Stress Resistance: Enhances plant salt tolerance
• Nutrient Efficiency: Increases fertilizer utilization by 20-30%
• Seaweed Extract Benefits: Most bioactive component in seaweed extracts

Hemoglobin Peptide

Source

Derived from hemoglobin through complex enzymatic hydrolysis process

Key Features

• Cost-Effective: Relatively low-cost protein option
• Amino Acid Rich: Contains plant-beneficial amino acids (proline, phenylalanine, valine, tryptophan)
• Unique Components: Rich in hemin chloride (structural analog of chlorophyll)
• Technical Superiority: High technical barriers in processing enhance product value

Specifications

• Protein Content: ≥90% (dry weight basis)
• Free Amino Acids: 8-10%
• Small Peptides: ≥80% (500-2000 Da)
• Balanced Nutrition: Contains all 18 essential amino acids

Agricultural Applications

• Photosynthesis Support: Hemin chloride aids chlorophyll function
• Plant Nutrition: Provides readily available amino acids and peptides
• Growth Promotion: Supports overall plant health and development
