Endophytic bacterial consortia as biocontrol of purple blotch and plant growth promoters of shallots

Abstract Endophytic bacteria have been reported to roles as biocontrol agents and plant growth promoters. The application of endophytic in the form mixed culture [consortia] will provide better effectiveness than when applied alone. This study aimed obtain a consortium that is effective biological control for purple blotch [ Alternariaporri ], promote yield shallots. research was arranged completely randomized design [CRD] consisting 7 treatments with three replications. used mixture two strains Bacillus sp., B. cereus , Serratia marcescens, subtilis, Azotobacter, Azospirillum P. fluorescens . variables observed this included disease progression [incubation period, incidence, severity], [number leaves height], [fresh weight dry bulbs]. results showed C sp. strain SJI, HI, marcescens ULG1E4 JBIE3] G Pseudomonas fluorescens, Serratiamarcescens were best consortia suppressing disease, well improving
