The bacterial strain TG6 was screened from the soil of a muskmelon greenhouse, which could effectively inhibit the growth of Sphaerotheca fuliginea, Fusarium oxysporum, Phytophthora melonis and Pseudoperonospora cubensis of muskmelons. TG6 was identified as Bacillus subtilis through morphological, physiological, biochemical and molecular studies. Taking TG6 as the original strain, TG67 and TG69 were obtained by He-Ne laser mutagenesis. The microbial compound antagonist strain TG67 and TG69 was prepared in the ratio of 1:1 and applied to the biological control of greenhouse melon. Muskmelon field experiments showed that the bactericide could effectively control the occurrence of various diseases of muskmelon in greenhouse. Bangladesh J. Bot. 52(4): 1047-1053, 2023 (December)

“…Suppression of disease by Bacillus spp. may be based on the production of a wide array of secondary metabolites (antibiotics, nonvolatile and volatile compounds) and show great potential by colonizing the root surface, causing fungal mycelia lysis, and promoting plant growth [44]. Major components of essential oils, such as menthone and menthol, may also be responsible for inhibiting the growth of the fungal pathogen.…”

Management Fusarium Wilt Disease in Tomato by Combinations of Bacillus amyloliquefaciens and Peppermint Oil

The most important disease of tomato is Fusarium wilt caused by Fusarium oxysporum f. sp. lycopersici (FOL). To control this disease, this study examined the combined use of bacterial bioagents and peppermint oil (PO). Seven bacterial isolates were collected from tomato plant rhizospheres and tested in vitro against FOL. The highest growth inhibition against FOL was shown by isolate No.3. This isolate was identified using 16S rRNA sequencing gene as Bacillus amyloliquefaciens (BA). Peppermint oil tested at different concentrations (1, 2, and 3%) against FOL mycelial growth in vitro showed the highest inhibition at 3%. The effects of BA, PO, and BA + PO in vitro on the seed germination and seedling vigor index of the tomato cv. ‘Tala F1’ was also tested. All “BA, PO, and BA + PO” treatments increased the percentage of germinated seeds and seedlings’ main shoots and root length compared to control treated seeds. The BA, PO, and BA + PO treatments were further tested under greenhouse and field conditions with pre-treated seedlings in FOL-contaminated soil. Under greenhouse conditions, each treatment decreased disease severity compared to untreated seedlings. Under field conditions, pre-treatment of tomato seedlings with BA and PO treatments reduced disease severity greater than BA + PO in combination and the mock-treated plants (66.6% for BA, 66.6% for PO and 55.3% for BA + PO, respectively). These findings support the use of BA or PO as bio-control agents against F. oxysporum in tomato. The interplay between peppermint oil, B. amyloliquefaciens, F. oxysporum, and the host plant requires further study to identify the causative mechanism for this increased disease resistance.
