“…In vitro study revealed significant (63%) inhibition of mycelial growth of the R. solani by the test bacterium compared to untreated control (Fig 1). Accordingly, several previous studies have reported the activity of Bacillus amyloliquefaciens against various fungal phytopathogens like Fusarium asiaticum, Fusarium graminearum, Rhizoctonia solani and Botrytis cinerea (Gupta et al, 2016;Boottanun et al, 2017;Ntushelo et al, 2019). The suppression of Rhizoctonia sp.…”

Background: Bacterial endophytes live inside the plant tissues and are known to play a crucial role in the functioning of host plants by influencing their physiology and development. Moreover, this group of bacteria could produce secondary metabolites to suppress plant pathogens and also produce compounds to promote plant growth. Methods: In this present study, Bacillus amyloliquefaciens was isolated from Oryzae officinalis and screened for antifungal activity against rice sheath blight pathogen, Rhizoctonia solani by dual culture assay. The secondary metabolites produced during the interaction of B. amyloliquefaciens with R. solani were characterized with pathogen-inoculated control and antagonist inoculated control through Gas Chromatography-Mass Spectrophotometry (GC-MS). Result: The isolated Bacillus amyloliqufaciens displayed antagonistic activity against Rhizoctonia solani which showed a 63% inhibiton in the mycelial growth of R. solani over control. Analysis of secondary metabolites from the zone of inhibition, confirmed the presence of unique biomolecules including -Propanamine, N,N,2-trimethyl, 1(2H)-Naphthalenone, 3,4-dihydro-6,7-dimethyl, Diethyl Phthalate, Dichloroacetic acid tridecyl ester, Hexadecen-1-ol trans-9, Glycine N-(N-glycyl-L-leucyl) and 2,6,10-Dodecatrien-1-ol, 3,7,11-trimethyl of antifungal and antimicrobial nature.

Fungal and viral infections represent a major cause of cocoa disease in agriculture. Plant protection through biological control is an alternative strategy in agriculture to control pests. Recognition of certain non-pathogenic rhizobacteria by plants can trigger a systemic resistance reaction that renders the host less susceptible to subsequent infection by a virulent agent. The impact of cocoa diseases as black pod, Cocoa Shollen Shoot Virus (CSSV), witches’ broom, and frosty pod rot, has increased dramatically in the world.This paper review emphasizes cocoa disease and utilisation of Bacillus subtilis as biocontrol agent against fungal and virus from cocoa disease in Côte d’Ivoire.

“…In this regard, Bacillus species have been used to control plant diseases as biological control agents (Gupta et al, 2016;Jangir et al, 2018;Le et al, 2019;Sunkad et al, 2023). Bacillus is known to produce a wide range of biocompounds such as bacteriocins and lipopeptides that inhibit fungal growth and limit the diseases (Pradhan et al, 2018;Rodríguez et al, 2018;Le et al, 2018Le et al, , 2019.…”

Background: The gummy stem blight caused by the fungal pathogen Didymella bryoniae (Auersw.) is a common and serious disease of watermelon plants in Vietnam. Bacillus species have been used to control plant diseases as biological control agents. The objectives of this studies were to determine the fungal inhibition of D. bryoniae and disease suppression of gummy stem blight under greenhouse by Bacillus sp. strains. Methods: The study was carried out at University of Agriculture and Forestry, Hue University during 2022-2023. Six potential Bacillus strains namely S1A1, S1F3, S13E2, S13E3, S18F11 and S20D12 isolated from stem-base of groundnut in central Vietnam were tested its fungal inhibition of D. bryoniae and disease suppression of gummy stem blight. Result: All tested strains of Bacillus sp. showed inhibition of the hyphal growth of D. bryoniae strain DB-01 in potato dextrose broth. Among the strains, Bacillus sp. S20F12 had highest inhibition of the growth of mycelia of D. bryoniae strain DB-01 with an antagonistic efficiency of 65.7% at 10 days after fungal inoculation. By 21 days after fungal inoculation, disease incidences were low in the plants treated with Bacillus sp. S20D12 and S1F3 by 46.6 and 50.0% and disease severity by 15,3% and 20.6%, respectively. As results, watermelon plants were prevented from damage of gummy stem blight caused by D. bryoniae strain BD-01 by Bacillus sp. S20D12 and S1F13. The results would contribute to the knowledge of antagonistic activities of the Bacillus to optimize the biological control against D. bryoniae.
