The reporter recently learned from Dalian Baolvbao Marine Life Science Research and Development Center Co., Ltd. that with the successful development of the biological pesticide chitosan citrate callus at the center, a root tree cancer disease cure problem has been solved. 99% of the cherry root cancer cure rate will make "cherry delicious tree is difficult to plant" this sentence in our history. According to reports, the new bio-pesticides use the domestic original chitosan citrate. This new glucosamine carboxyl derivative can induce plants to produce resistant protein, phytoalexin, chitinase, chitosanase, Β-1 and 3-glucanases can effectively control diseases caused by fungi, bacteria, and viruses. After three years of trials and demonstrations, the expanded trial of cherry root cancer prevention and treatment in multiple regions has resulted in a cure rate of 99%, setting a world record for cherries. The highest rate of cure for root cancer. Root canker disease, also known as root nodule disease, is a serious disease of many plants. It is caused by pathogenic bacteria that invade the roots of plants and forms a tumor. The incidence rate in cherry trees is 20% to 60%, and the highest is 90%, causing growth retardation and yield. Reduced, shortened life, or even destroyed the garden. Cherries are hailed as "gemstone fruits." China has included the introduction of foreign cherry into the "863" plan, and plans to establish a cherry cultivation demonstration base with a total area of ​​2,000 hectares nationwide after five years. The high incidence of cherry root cancer has challenged this plan. It is understood that the root cancer disease has a wide range of hazards and occurs in a variety of fruit trees, forest trees, flowers, and even melons. At present, the company is demonstrating and verifying 5,000 acres of farmland in Ganjingzi District of Dalian and gradually expanding the application of this new technology. The preliminary results show that this biopesticide can be used in combination with farmyard manure and a small amount of other biological pesticides without using chemical pesticides and using 1/3 less fertilizer, which can save more than 120 yuan of chemical pesticides per acre. Save more than 50 yuan in fertilizer expenditure.
