Chemphy Chemical’s amino-oligosaccharin (Hope) is fermented using the biodegradable enzyme technology developed by Dalian Institute of Chemical Physics, Chinese Academy of Sciences. It is a green, pollution-free, residue-free, non-phytotoxic, and degradable plant resistance inducer. Mainly by stimulating the plant's own immune response, the plant can obtain systemic disease resistance and stress resistance, and at the same time have the functions of regulating plant growth, development, reproduction, etc., so as to solve the sub-health problems in the process of plant growth.

Hope is a product obtained by deacetylating and special enzyme degrading chitin extracted from marine shell organisms such as shrimp shells, crab shells and other organisms after decalcification. Hope is different from other amino-oligosaccharides in that it is degraded by a unique biological endonuclease, so that the degradation length of chitosan can reach the oligoamino-oligosaccharides linked by 2-8 glucosamine. The molecular weight of the amino-oligosaccharins obtained in this way is between 300-2600, which is suitable for plant absorption and utilization.
