“…We developed a novel bioorganic fertilizer (BIO) by fermenting mature compost with the antagonistic microbe, P. polymyxa. This bioorganic fertilizer was previously shown to suppress Fusarium wilt disease, and promote growth of watermelon and cucumber plants in greenhouse and field experiments (Zhang et al 2008;Wu et al 2008). However, field application of this bioorganic fertilizer is costly for farmers and the way it is applied to the soilplant system is not in accord with the ecological requirements of the biocontrol agents.…”

More effective ways of applying biocontrol products should be developed based both on the characteristics of the biocontrol agents and the normal practices of the agricultural producer. A new system was developed to improve the biocontrol efficacy of Fusarium wilt for watermelon production, and this system was tested in pot and field experiments. Biocontrol was achieved by applying a novel bioorganic fertilizer product (BIO) to Fusarium-infested soil. The best biocontrol was obtained by application of a bioorganic fertilizer, BIO, into soil during the nursery phase of watermelon seedling followed by a second application to Fusarium-infested soil when watermelon seedlings were transplanted. In comparison with the controls, the incidence of the disease was reduced by 60-100% in the pot experiment and by 59-73% in the field experiment when the BIO was applied during the nursery stage. After application of BIO during the nursery stage, the number of colony-forming units of Fusarium oxysporum in rhizospheric soil was significantly (P \ 0.05) inhibited compared to the controls. An in vitro experiment showed that the antagonist Paenibacillus polymyxa in the BIO could effectively colonize the rhizosphere of watermelon and proliferate along the extending plant roots. This inhibited growth of Fusarium oxysporum in the rhizosphere of watermelon and protected the watermelon roots from attack by the pathogens. The method used for biocontrol Fusarium wilt disease in watermelon should be a useful strategy to improve field efficacy of other biocontrol agents.

“…cucumerinum is the primary cause of vascular wilt in cucumber plants, and it causes substantially reduced cucumber yields in China (1)(2)(3). The symptoms of the disease begin with the development of necrotic lesions, followed by foliar wilting as the pathogen invades the vascular system of the plant, and eventually, plant death (4). Chemical fungicides and soil disinfestations by treating with methyl bromide are the main strategies for controlling cucumber Fusarium wilt.…”

cBacillus amyloliquefaciens strains are capable of suppressing soilborne pathogens through the secretion of an array of lipopeptides and root colonization, and biofilm formation ability is considered a prerequisite for efficient root colonization. In this study, we report that one of the lipopeptide compounds (bacillomycin D) produced by the rhizosphere strain Bacillus amyloliquefaciens SQR9 not only plays a vital role in the antagonistic activity against Fusarium oxysporum but also affects the expression of the genes involved in biofilm formation. When the bacillomycin D and fengycin synthesis pathways were individually disrupted, mutant SQR9M1, which was deficient in the production of bacillomycin D, only showed minor antagonistic activity against F. oxysporum, but another mutant, SQR9M2, which was deficient in production of fengycin, showed antagonistic activity equivalent to that of the wild-type strain of B. amyloliquefaciens SQR9. The results from in vitro, root in situ, and quantitative reverse transcription-PCR studies demonstrated that bacillomycin D contributes to the establishment of biofilms. Interestingly, the addition of bacillomycin D could significantly increase the expression levels of kinC gene, but KinC activation is not triggered by leaking of potassium. These findings suggest that bacillomycin D contributes not only to biocontrol activity but also to biofilm formation in strain B. amyloliquefaciens SQR9.

“…This result indicates that the BIO application inhibits the growth of F. oxysporum, which supports the report by Liu et al [15] that applications of bio-organic fertilizer fortified with Brevibacillus brevis L-25 and Streptomyces rochei L-9 significantly decrease the Ralstonia solanacearum population in tobacco rhizosphere soil. Zhang et al [40] documented that the application of B. subtilis SQR-5-fortified bio-organic fertilizer at the cucumber seedling stage significantly reduced the F. oxysporum population in the rhizosphere soil. This is the first report to investigate the biocontrol of vanilla stem and root rot disease and the promotion of plant growth through the application of a novel B. cereus-fortified bio-organic fertilizer.…”

A lipopeptide-producing bacterium, Bacillus cereus (F-6), was isolated from the rhizosphere soil of a healthy vanilla (Vanilla planifolia) plant cultivated on a plantation under 21 years of continuous cropping with vanilla. A pot experiment was conducted to investigate the effects of the green fluorescent protein-tagged F-6 (F-6-gfp) and its bio-organic fertilizer (BIO) on vanilla plant growth and stem and root rot disease, using the same plantation soil. The application of BIO significantly increased the vanilla plant root, stem and leave dry weights; however, there was not a significant difference between the F-6-gfp-inoculated treatment and the control. Meanwhile, the BIO application also significantly reduced the severity of stem and root rot disease compared to the control. The rhizosphere soil population of Fusarium was approximately 10-fold smaller in the BIO treatment compared to the control treatment at 150 days after transplantation. The number of B. cereus F-6-gfp in the rhizosphere soil of the BIO treatment remained significantly higher than that of the F-6-gfp-inoculated treatment throughout the experiment. In conclusion, F-6-gfp successfully colonized the rhizosphere soil in the BIO treatment, promoting vanilla plant growth, reducing the disease severity index, and decreasing the Fusarium population number, helping to remove barriers to the continuous cropping of vanilla.
