Application of sophora tonkinensis endophytic fungus TRXY-34-1 in prevention and treatment of panax notoginseng black spot

Abstract

The invention discloses sophora tonkinensis endophytic fungus TRXY-34-1. The sophora tonkinensis endophytic fungus TRXY-34-1 has the type name of Fusarium solani TRXY-34-1, an ITS sequence of the Fusarium solani TRXY-34-1 is as shown in SEQ ID NO. 1, and the Fusarium solani TRXY-34-1 is collected by the General Microorganisms Center of China Committee for Culture Collection of Microorganisms, which is located at Institute of Microbiology, Chinese Academy of Sciences, 3#, 1# Courtyard, Beichen West Road, Chaoyang District, Beijing, on May 13, 2015 and has the collection number of CGMCC No. 10767. According to the sophora tonkinensis endophytic fungus TRXY-34-1, the endophytic fungus Fusarium solani TRXY-34-1 is obtained through being separated from roots of a medicinal plant, i.e., Sophora tonkinensis and carrying out screening for the first time and has a powerful inhibiting action on Alternaria panax Whetzel, and thus a broad application prospect is brought to the field of biological control on panax notoginseng fungal diseases.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to the application of a Vietnamese Sophora japonica endophyte TRXY-34-1 in the prevention and treatment of Panax notoginseng black spot. Background technique [0002] The prevention and control of plant diseases in modern agriculture is overly dependent on the use of chemical pesticides. The application of a large number of chemical pesticides not only has long-term damage to the ecological environment, but also causes the quality of agricultural products to decline, pesticide residues exceed the standard, pathogenic bacteria are resistant to drugs, and are harmful to humans and animals. Many questions. It is of great significance to find safer and more effective methods of disease control, and the use of biological methods to prevent and control plant diseases can effectively solve the above problems. [0003] Panax notoginseng F.H.chen, also known as Tianqi, Jinbuhuan, etc., has sign...

AI Technical Summary

Problems solved by technology

In the traditional authentic production area of ​​Sanqi in Guangxi, due to the low altitude and high temperature and humidity weather conditions, this disease often occurs at the same time, resulting in a large amount of production reduction or even failure of Sanqi, and brought huge economic losses to the growers.

In order to control this fungal disease, a large amount of chemical pesticides are used, resulting in a large amount of pesticide residues in Panax notoginseng products, seriously polluting the environment, and greatly threatening people's health
