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, suitable compatible.
Dora Sailor is a chitosan oligosaccharide formulation to activate plants’ resistance ability to diseases & stress.
It contains chitosan oligosaccharide (enzymatic hydrolysis process), 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, stimulate roots growth
Foliar spraying – induce crops’ resilience to stress & diseases

Benefits of Dora Sailor
1. Increase seed germination
After seed treatment, it not only can improve seed vigor & germination rate but also can stimulate the seed’s immune & growth system to improve the disease-resistance & growth rate.
It has been proven that we apply on ryegrass seed, its germination index increased 33.5%, and the vitality index increased by 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 viruses, fungus, and bacteria.
3. Improve soil micro-environment
Control harmful nematodes Apply Chitosan oligosaccharide in the soil is sufficient to control nematodes. Cos can stimulate the breeding of chitinolytic microbes to ruin the cuticle of nematodes eggs.
Increase the growth of plant-beneficial rhizobacteria. After applying Chitosan oligosaccharide, beneficial microbes can quickly prosper, and their activity stimulated. Great help to build a healthy soil micro-environment.
