According to reports, the new bio-pesticide uses the domestic chitosan amine citrate, this new chitosan carboxylated derivative can induce plant resistance protein, phytoalexin, chitinase, chitinase, -1-1 and 3-glucanase can effectively prevent diseases caused by fungi, bacteria and viruses.

At present, the company is demonstrating and demonstrating in 5,000 mu of farmland in Ganjingzi District of Dalian, gradually expanding the application field of this new technology. Preliminary results show that this bio-pesticide can be used in combination with farmyard manure and a small amount of other bio-pesticide without chemical pesticides and less than 1/3 of chemical fertilizers, so that it can save more than 120 yuan per acre of chemical pesticides.
