“…Rahman et al (2016) reported the efficiency of B. amyloliquefaciens in inhibiting mycelial growth of S. sclerotiorum causing white mold in mustard. Similarly in our study, B. amyloliquefaciens (VB7) effectively inhibited mycelial growth and sclerotial production to a greater extent, significantly different from other treatments.…”

“…Apart from this, Bacillus is known to produce volatile and non-volatile antimicrobial compounds that synergistically aid in curtailing plant diseases (Fernando et al, 2005; Mora et al, 2011). Antagonistic potential of Bacillus spp., against S. sclerotiorum has been explored in various host plants like mustard (Rahman et al, 2016), canola (Fernando et al, 2007; Kamal et al, 2015), soybean (Zhang and Xue, 2010), tomato (Abdeljalil et al, 2016). However, in case of carnations this is the first study regarding the management under protected cultivation.…”

Bacillus species are widely exploited as biocontrol agents because of their efficiency in impeding various plant pathogens with multifaceted approach. In this study, Bacillus species were isolated from rhizosphere of various plants viz., carnations, cotton, turmeric, and bananas in Tamil Nadu state of India. Their potential to control the mycelial growth of Sclerotinia sclerotiorum was assessed in vitro by dual plate and partition plate techniques. B. amyloliquefaciens strain VB7 was much effective in inhibiting mycelial growth (45% inhibition of over control) and sclerotial production (100%). PCR detection of AMP genes revealed that B. amyloliquefaciens (VB7) had a maximum of 10 diverse antibiotic biosynthesis genes, namely, ituD, ipa14, bacA, bacD, bamC, sfP, spaC, spaS, alba, and albF, that resulted in production of the antibiotics iturin, bacilysin, bacillomycin, surfactin, subtilin, and subtilosin. Further, metabolites from B. amyloliquefaciens strains VB2 and VB7, associated with inhibition of S. sclerotiorum, were identified as phenols and fatty acids by gas chromatography mass spectrometry (GC-MS). Delivery of bacterial suspension of the effective strains of Bacillus spp. as root dip was found promising for the management of stem rot of cultivated carnations. Minimal percent disease incidence (4.6%) and maximum plant growth promotion was observed in the plants treated with B. amyloliquefaciens (VB7).

“…Mahartha and Suprapta [69] have reported on the effectiveness of a strain of Enterobacter as a suppressant of damping-off in the soybean by Sclerotium, while Krishnamoorthy et al [70] isolated a strain of B. cereus capable of reducing the in vitro mycelial growth of S. sclerotiorum by 39% in comparison with the control. Rahman et al [71] demonstrated that isolates of Bacillus inhibited the mycelial growth and suppressed the formation of sclerotia in S. sclerotiorum during in vitro assays. Deformities and lysis were observed in the cell walls of the mycelia, as well as abnormalities in the apothecium and the failure of the ascospores to germinate.…”

Sclerotinia sclerotiorum is a necrotrophic parasitic fungus that causes Sclerotinia stem rot (SSR), which is currently one of the most difficult agronomic crop diseases to control. A number of plants of the Brazilian Cerrado biome have been shown to be important sources of symbiotic microorganisms with biotechnological potential, so we decided to test the potential of bacteria isolated from the dwarf jelly palm, Butia archeri (Arecaceae) for the control of the pathogenic effects provoked by S. sclerotiorum. For this, we bioprimed seeds and evaluated the effects of this biopriming on the OJIP transient patterns prior to and following infection by the phytopathogen. Plants treated with the BA48R strain of Enterobacter sp., and in particular, those treated with the BA88R strain of Bacillus cereus presented the best results in terms of the loss/gain of the physiological and symptomatological variables evaluated. The plants bioprimed with BA88R presented high post-infection levels of total chlorophyll (33.35 FCIs) and chlorophyll a (26.39 FCIs), maintained a high Nitrogen Balance Index (NBI = 18.87), and synthesized low concentrations of flavonoids (1.39). These plants also maintained high levels of PIABS (1.111) and PITOTAL (1.300) following infection, and low levels of Di0/RC (0.602), which indicates that, in the presence S. sclerotiorum, the efficiency of the photosynthesis in the plants treated with these bacteria was less affected in the reaction centers, as confirmed by the negative amplitude recorded in the L band. The present study reconfirms the importance of the use of chlorophyll fluorescence for the diagnosis of disease and conditions of stress in crop plants, in addition to demonstrating the effectivenesss of the BA48R bacterial strain and, in particular, the BA88R strain on systemic resistance induction and suppression of S. sclerotiorum in Glycine max plants, with enormous potential for the development of more sustainable agricultural processes.

“…This may be explained by synergistic or antagonistic interaction between mixed BCAs that impacts their relative modes of action and the additive effects of their antifungal metabolites [36]. In fact, even if a single BCA has the ability to combat a plant pathogen [37], combination of antibiotic-producing strains may act synergistically in restricting growth and plant colonization abilities of targeted pathogens. Single use of BCAs for disease management might be also responsible for its inconsistent performance under field conditions resulting in inadequate site colonization and fluctuations in their abilities to release antimicrobial compounds [38].…”
