Abstract Among 131 rhizobacteria isolates, 29 potentially antagonistic strains were screened in in vitro assays. The five antagonistic Bacillus spp. Rb29, Rb6, Rb12, Rb4, and Rb15 showed the most inhibitory effect against FOC1 (from 25.63 to 71.11%), mycelial growth, and FOC2 (from 28.43 to 60.65%) in vitro. Results also revealed that production of volatile metabolite, components and inhibition of the test pathogen by volatile metabolites varied among different antagonistic rhizobacteria. Isolates Rb29, Rb6, Rb12, Rb4, and Rb15 produced more volatile metabolites which inhibited mycelial FOC growth by 40%. Chickpea Fusarium wilt severity caused by FOC1 was reduced from 60 to 99% in the susceptible cultivar ILC 482 treated with antagonistic Bacillus spp. (Rb29, Rb6, Rb12, Rb4, and Rb15) in pot assays and by 98, 81, 68, 64, 57.20%, respectively, in the field trials. As for their beneficial effects on disease control, the results revealed that Bacillus spp. may improve plant growth and disease control.

Yanti Y, Warnita, Reflin, Busniah M. 2018. Indigenous endophyte bacteria ability to control Ralstonia and Fusarium wiltdisease on chili pepper. Biodiversitas 19: 1532-1538. Bacterial wilt and Fusarium wilt caused by Ralstonia syzigii subsp. indonesiensisand Fusarium oxysporum f.sp. capsici (Foc), respectively are the most damaging vascular pathogens in chili pepper (Capsicum annuumL.) and many other crops limiting their production, worldwide. Various strategies have been developed to control wilt pathogensincluding the application of chemical pesticides, which generally considered as the most effective and fastest strategy for plant diseasemanagement. However, effective chemicals for wilt pathogens of chili pepper plants are not available, yet. Endophytic bacteriaconsidered as one of options to control vascular wilt disease because of its ability to live and colonize in internal roots of plants.Previous research has been done to select endophytic indigenous bacteria isolates which can promote growth rate of chili pepper. Thepurpose of the research was to identify the selected indigenous endophyte bacteria isolates acquired from our previous study using 16SrRNA identifications and to screen the selected endophytic indigenous bacteria to control both R. syzigii subsp. indonesiensis and Foc.Results from 16S r RNA analysis showed that all of 9 isolates were identified as Bacillus spp., such as Bacillus cereus ATCC 14579,Bacillus pseudomycoides strain NBRC 101232, Bacillus toyonensis strain BCT-7112, Bacillus thuringiensis strain ATCC 10792,Bacillus weihenstephanensis strain DSM 11821, Bacillus mycoides strain 273, Bacillus cereus strain NBRC 15305, Bacillusbingmayongensis strain FJAT-13831 and Bacillus manliponensis strain BL4-6. Our results showed that most of endophytic bacteriaisolates application could control both bacterial and Fusarium wilt diseases. Six out of nine isolates can suppress R. syzigii subsp.indonesiensis without developing any symptoms and five isolates could suppress symptoms of Foc. Isolates Bacillus pseudomycoidesstrain NBRC 101232 Bacillus thuringiensis strain ATCC 10792 and Bacillus mycoides strain 273 were potential for control Foc and R.syzigii subsp. indonesiensis in chili pepper.
