Beschreibung
Zusammenfassung:The invention discloses a cistanche deserticola stem rot antagonistic bacterium, a biological agent and application of the cistanche deserticola stem rot antagonistic bacterium and the biological agent, the strain is the antagonistic bacterium WLKYLW-9, belongs to salt-tolerant bacillus and is preserved in the China General Microbiological Culture Collection Center (CGMCC), and the preservation number is CGMCC No.26809. The invention provides a WLKYLW-9 strain which has an inhibiting effect on cistanche stem rot germs, and solves the problem that the cistanche stem rot germs are promoted to generate drug resistance due to long-term use of chemical agents in the prevention and treatment of the cistanche stem rot; meanwhile, the WLKYLW-9 strain can be used as an active component to prepare a biopesticide, the stem rot of cistanche deserticola is prevented and treated, the yield of cistanche deserticola is increased, the income of farmers is increased, and the WLKYLW-9 strain has great economic benefits. 本发明公开了一
