Oligochitosan

Light yellow, yellow, odorless, tasteless, soluble in water

Oligochitosan can change the soil flora and promote the growth of beneficial microorganisms. Oligochitosan can also induce plant disease resistance, produce immunity and kill a variety of fungi, bacteria and viruses, and be effective against wheat mosaic disease and cotton verticillium wilt. disease, rice blast, tomato late blight and other diseases have good control effects, and can be developed into biological pesticides, growth regulators and fertilizers.

Oligochitosan: A Potent Bio-Stimulant for Modern Agriculture

Definition:
Oligochitosan is a low-molecular-weight derivative of chitosan obtained through enzymatic or chemical hydrolysis. It retains the biological properties of chitosan but offers enhanced solubility and bioactivity, making it highly effective in agricultural applications.

Key Characteristics of Oligochitosan:

1. Chemical Formula:$(C_6H_{11}NO_4)_n$, with a smaller molecular size than chitosan.

2. Molecular Weight: Typically < 10 kDa.

3. Solubility: Fully soluble in water, even at neutral pH.

4. Biodegradability: Rapidly decomposed into natural components in the environment.

5. Non-Toxicity: Safe for plants, animals, and humans.

Functions of Oligochitosan in Agriculture:

1. Plant Growth Regulator:

   • Enhances cell division and elongation.

   • Promotes chlorophyll synthesis and photosynthesis efficiency.

2. Immune Booster:

   • Activates plant defense mechanisms against pathogens.

   • Induces production of antimicrobial compounds in plants.

3. Pest and Disease Management:

   • Inhibits growth of fungi, bacteria, and viruses.

   • Acts as a natural repellent for certain pests.

4. Stress Mitigation:

   • Improves plant resilience to drought, salinity, and temperature extremes.

5. Soil Microbial Stimulation:

   • Encourages beneficial microbial activity in the rhizosphere.

Applications of Oligochitosan:

1. Seed Treatment:

   • Enhances germination and early-stage growth.

2. Foliar Spray:

   • Applied directly to leaves to improve disease resistance and growth.

3. Soil Amendment:

   • Improves soil fertility and supports microbial ecosystems.

4. Post-Harvest Use:

   • Extends shelf life of fruits and vegetables by preventing microbial spoilage.

Advantages of Oligochitosan:

• Eco-Friendly: 100% biodegradable and non-polluting.

• Highly Effective: Requires lower dosages compared to conventional chitosan.

• Versatile: Suitable for various crops and agricultural practices.

• Improved Solubility: Easier to use in aqueous formulations.

Usage Recommendations:

• Concentration: 50–200 ppm, depending on the application.

• Application Method: Spraying, soaking, or soil drenching.

• Frequency: 2–3 applications per growth cycle for optimal results.

Storage and Handling:

• Storage Conditions: Keep in a cool, dry place, away from moisture and direct sunlight.

• Shelf Life: Up to 2 years under proper storage conditions.

Oligochitosan represents a breakthrough in sustainable agriculture, offering a powerful, natural alternative for enhancing crop health, productivity, and resilience.
