Due to the high environmental risk of traditional chemical pesticides, Biological solutions for controlling plant diseases are highly recommend. Chitosan oligosaccharide is the biological control solution with the features of non-toxic, Bio-Degradable, good compatible.
Dora Sailor contains chitosan oligosaccharide (enzymatic hydrolysis), which has outstanding water-solubility, high biological activity and easily absorbed utilized by crops.
For now, Dora Sailor are widely used on
Seed pretreatment – disease resistance, strengthen seedlings
Soil treatment – prevent harmful pathogens and nematodes, improve soil condition, stimulte roots growth
Foliar spraying – induce crops’ resistance to stress & diseases
- Dora Sailor Powder………………≥90% Cos
- Dora Sailor Liquid………………..≥ 10% Cos
Compare to normal chitosan oligosaccharide
- Molecular weight＜1500, high activity
- Excellent water solubility & flowability
- Obtained by degradation of chitosan by enzymatic hydrolysis
Benefits of Dora Sailor
1. Increase seed germination
It has been experimentally demonstrated that we apply on rye grass seed, its germination index increased 33.5% and vitality index increased 59.5%.
2. Increase resistance ability to stress & diseases
For stress, it can induce plants general regulation of endogenous hormones.
- Improve plant’s water retaining capacity
- increase the lodging/drought-resistance
- Help the recovery of damaged plants
For diseases, it can thicken the plant’s cell walls and instantly induce defense reactions to various kinds of virus, fungus and bacteria.
3. Improve soil micro-environment
Control harmful nematodes Apply Chitosan oligosaccharide in soil is effective to control nematodes. Cos can stimulate the breeding of chitinolytic microbes to ruin the cuticle of nematodes eggs.
Increase growth of plant-benificial rhizobacteria After applying Chitosan oligosaccharide, beneficial microbes can easily prosper and their activity stimulated. Great help to build a healthy soil micro-environment.
How to use Chitosan oligosaccharide

General principles for the mixing of Cos with pesticides
Pay attention to the mixing sequence: first dilute the Cos product according to the usage instructions, then dilute the pesticide into the mother liquor, and finally pour the pesticide mother liquor into the Cos dilution. The order of compounding cannot be reversed.
