Agricultural Grade COS

Product Name: Agricultural grade chitosan oligosaccharide

English Name: Chitosan oligosaccharide, Chitooligosaccharide, Chitosan Oligomers, Chitooligomer, Oligochitosan, Chitosan Oligosaccharin, Chitosan Oligo Saccharins, COS.

Origin From: Crab shells

Molecular Formula: (C6H11NO4)n(n=2~10)

Chitosan oligosaccharide could be considered as water-soluble chitosan which is made from depolymerizing chitosan by enzyme hydrolysis. And its average molecular weight (≤3kDa) our agriculture COS is≤1.5kDa ,It is much lower than chitosan's (≥100KDa). The low molecular weight benefits prominent water solubility and bioactivities which can be used in agriculture.

                                                                             Functions

1.  Activate Plant Defense Responses against Fungal, Bacterial, Vivus Diseases & Environment Stress

- Activate and induce plant immune reactions & plant self-defence machinery to increase the resistance ability under environment stress(heat, cold, drought, etc)

- Activate plants' defense response in the treated plants and stimulate additional biochemical pathways that strengthen the plant structure and act against the fungal, bacterial and vivus diesases.

 

2.  Promote Plant Growth and Enhance Yield Potential

- Promote plant seed germination and seeling growth

- Promote plant root, stalk and leaf growth  

- Promote plant fruit growth, and improve yield & profits  

- Mineral absorption accelerant

 

3.  Improve Soil Structure

- Prevente and Restrain nematodes

- Activating the growth of useful microbes, suppressing harmful microbes

- Restoration of soil ecology 


                                                                     Application&Dosage

- New biological fertilizers (plant growth regulator, foliar fertilizer, flushing fertilizer, seed coating agent) and biological pesticides,etc.

 

1. Seed treatment

100ppm seed soaking for 12-24 hours, or 500ppm seed dressing or spraying

 

2 Foliar spray

50-100ppm (manual or mechanical sprayer), the flying defense concentration needs to be increased

 

3 Underground fertilization

225-375 grams Chitooligosaccharides per hectare

 

Best use time

1. During the critical period of crop growth, including seed, seedling period, before and after planting, before flowering, swelling period, and filling period

2. Before the adversity, freezing damage, drought, waterlogging, and disease

 

Onset of Chitooligosaccharides:

Effective period 24-36 hours

The validity period is 7-9 days.
