Abstract

The invention discloses application of sarcandra glabra endophyte RJ-1 in inhibiting phytopathogens. The phytopathogens include colletotrichum dematium, notoginseng botrytis cinerea, notoginseng rootrot fungus, notoginseng alternaria brassicicola, notoginseng anthracnose, banana leaf spot fungus, banana anthracnose, banana oxysporum, cardamom leaf spot fungus, watermelon oxysporum, picria leaf spot fungus, curcuma kwangsiensis leaf spot fungus, tobacco grey mould fungus, blumea balsamifera brown spot fungus, momordica grosvenori leaf spot fungus or Escherichia coli. The sarcandra glabra endophyte RJ-1 has good inhibiting effect on various phytopathogens and has various antibacterial active substances, and a new way is provided for biological pesticide and natural antibacterial substance screening.

Description

technical field [0001] The invention relates to the technical field of plant pathogenic bacteria inhibition. More specifically, the present invention relates to the use of a sarcocarp endophyte RJ-1 for inhibiting plant pathogenic bacteria. Background technique [0002] It is the dried whole herb of the perennial herbaceous plant Coralia genus in the family Chrysanthemum, also known as Jiujiecha, Elderberry, etc. It is mainly distributed in South China, East China, and Southwest provinces in my country, and it is also found in Korea, Japan, Southeast Asia, and India. distributed. It has the functions of clearing away heat and cooling blood, promoting blood circulation and eliminating spots, dispelling wind and dredging collaterals, etc. It is used to treat blood heat purpura, purpura, rheumatic arthralgia, bruises and other diseases. It is a species included in the Chinese Pharmacopoeia and an important traditional Yao medicine in Guangxi One of the important wind medicine ...
