Root rot disease is a serious infection leading to production loss of Chinese wolfberry ( Lycium barbarum ). This study tested the potential for two bacterial biological control agents, Bacillus amyloliquefaciens HSB1 and FZB42, against five fungal pathogens that frequently cause root in wolfberry. Both FZB42 were found inhibit mycelial growth, vitro planta , as well promote growth seedlings. In fact, biocontrol experiment showed efficiency 100% with at least one treatment involving each strain Fusarium oxysporum . Metagenomic sequencing was used assess community shifts rhizosphere upon introduction strain. Results differentially altered abundances different taxa present positively influenced various functions inherent bacteria. highlights application method suppression wolfberry, which useful agricultural extension agents commercial growers.
