Chitosan Oligosaccharide (NY-COS): Advanced Plant Immune Elicitor & Biostimulant

Chitosan Oligosaccharide (COS) is a revolutionary biological tool designed for modern, sustainable agriculture. Derived from marine chitin through specialized enzymatic hydrolysis, NY-COS features an ultra-low molecular weight (<1500 Da), ensuring 100% water solubility and immediate bioavailability for plants.

Unlike standard chitosan, NY-COS functions as a potent elicitor, triggering the plant’s internal defense systems (Systemic Acquired Resistance) to naturally combat pathogens and environmental stress.

Why Choose NY-COS?

1. Instant Systemic Acquired Resistance (SAR)

NY-COS acts as a “natural vaccine.” When applied, it mimics a fungal attack, causing the plant to produce defense enzymes like chitinase and glucanase. This primes the crop to resist real infections from fungi, bacteria, and viruses.

2. Superior Solubility and Equipment Safety

With a high clarity rating (240), our Chitosan Oligosaccharide leaves no grit or residue. It is perfectly suited for:

• Hydroponic Systems: Won’t clog emitters or bio-film lines.

• Foliar Sprayers: Ensures uniform coverage without nozzle blockages.

3. Abiotic Stress Mitigation

NY-COS increases the accumulation of soluble sugars and proline in plant tissues, significantly improving tolerance to drought, high salinity, and extreme temperature fluctuations.

4. Soil Microbiome Enhancement

In soil applications, NY-COS promotes the growth of beneficial microorganisms like Actinomycetes while suppressing harmful soil-borne pathogens, creating a healthy rhizosphere.

Application Methods and Dosage

To maximize the efficacy of Chitosan Oligosaccharide, use the following guidelines:

Frequently Asked Questions (FAQ)

1. What is the molecular weight of NY-COS?

NY-COS has a molecular weight of less than 1500 Daltons. This is critical for SEO and performance because standard chitosan is often too large ($> 100,000$ Da) for plants to absorb through leaf stomata or root membranes.

2. Is Chitosan Oligosaccharide compatible with chemical fertilizers?

Yes. NY-COS is highly stable and compatible with most NPK fertilizers and pesticides. In fact, it often acts as a synergist, improving the absorption and efficiency of the products it is mixed with.

3. How does it affect fruit quality and shelf life?

Studies show that COS increases fruit firmness, Vitamin C content, and total phenolic levels. It also creates a natural protective film that reduces respiration, extending the post-harvest shelf life of fruits like strawberries and tomatoes.

4. Is it organic-certified?

Our NY-COS is derived from natural, sustainable crustacean sources and is biodegradable, making it an ideal choice for Integrated Pest Management (IPM) and organic-leaning farming practices.
