“…The researchers found that the activities of catalase and peroxidase enzymes involved in host H2O2 detoxification were reduced, suggesting enhanced defense system of the host plant. Soil organic amendment with dried powder of Withania somnifera and W. coagulan had a significant effect on improving plant growth characters in vivo, reducing bacterial load g -1 soil and affecting bacterial wilt disease severity by decreasing the AUDPC values (Khan et al 2019a;Najeeb et al 2019). Saponins and steroids were also reported to be present in significant amounts in leaves of W. somnifera (Panchal et al 2016).…”

The ability of some medicinal plants was explored to control bacterial canker of tomato caused by Clavibacter michiganensis subsp. michiganensis. The plants tested included Peganum harmala, Allium sativum, Withania somnifera, Melia azedarach, Calotropis procera, Mentha piperita and Nerium oleander. Aqueous extracts of P. harmala and M. piperita proved to be very effective under in vitro conditions against Clavibacter michiganensis subsp. michiganensis. In in vivo studies, the highest dose of dried powder of P. harmala and M. piperita kg−1 of soil decreased disease severity significantly. Other yield-contributing parameters were also enhanced by the application of dried powder and no phytotoxicity was observed at given concentrations. Alkaloids, tannins, glycosides, flavonoids and saponins were detected in aqueous extracts of P. harmala, W. somnifera, M. azedarach, C. procera and M. piperita. Dried powders of P. harmala and M. piperita could be incorporated as an integral part in the integrated disease management programs against Clavibacter michiganensis subsp. michiganensis.

“…The green synthesized ZnO nanoparticles and W. coagulans leaf extract were tested alone or in combination for their antibacterial activity against phytopathogenic bacteria R. solanacearum . Agar well diffusion technique was employed (Najeeb et al, 2019). Briefly, a petri dish was filled with 20 ml Luria Broth medium containing 0.5 ml bacterial suspension with 10 8 CFU per ml concentration (OD 600 = 0.3), then cooled (Khan et al, 2020).…”

Aims Because of severe economic losses and food security concerns caused by plant pathogenic bacteria, Ralstonia solanacearum, there is a need to develop novel control methods. This study was aimed to green synthesize the zinc oxide nanoparticles (ZnO NPs) through Withania coagulans leaf extracts and checked their antibacterial potential alone or in combination with W. coagulans leaf extract for the management of R. solanacearum causing bacterial wilt disease in tomato. Methods and Results ZnO NPs were synthesized through an eco‐friendly approach using leaves extract of W. coagulans and characterized through various spectroscopic approaches, that is Fourier transform infrared spectroscopic, UV–visible spectroscopy and energy dispersive spectroscopy. The antibacterial effect of W. coagulans leaf extract and ZnO NPs alone and in combination was tested in vitro and in vivo against bacterial wilt pathogen in tomato plants. The results showed that combine application of leaf extract and ZnO NPs inhibited in vitro growth of R. solanacearum more than applying alone. Three application times (0, 6 and 12 days before transplantation) of leaf extract, ZnONPs and their combine application were tested in vivo. The combine treatment and longest application time (12 days before transplantation) were more effective in suppressing soil population of R. solanacearum, reducing disease severity and enhancing plant growth than applying alone and smaller application time. Conclusion It is concluded that W. coagulans leaf extract and ZnO NPs have strong antibacterial potential against R. solanacearum in vitro and in vivo. Significance and Impact of Study The results of this study suggest the potential application of leaf extract and ZnO nanoparticles for controlling R. solanacearum as safe, eco‐friendly and less expensive integrated disease management strategy in tomato crop.

The current study depicts the comparative effects of nanogel using Withania coagulans extract, pregabalin alone, and a co-combination gel. The gels prepared were then analyzed for conductivity, viscosity, spread ability, globule size, zeta potential, polydispersity index, and TEM. The globule size of the co-combination gel, determined by zeta sizer, was found to be (329 ± 0.573 nm). FTIR analysis confirms the successful development of gel, without any interaction. Drug distribution at the molecular level was confirmed by XRD. DSC revealed no bigger thermal changes. TEM images revealed spherical molecules with sizes of 200 nm for the co-combination gel. In vivo studies were carried out by infliction of third degree burn wounds on rat skin, and they confirmed that pregabalin and Withania coagulans heals the wound more effectively, with a wound contraction rate of 89.95%, compared to remaining groups. Anti-inflammatory activity (IL-6 and TNF-α), determined by the ELISA technique, shows that the co-combination gel group reduces the maximum inflammation with TNF-α value (132.2 pg/mL), compared to the control (140.22 pg/mL). Similarly, the IL-6 value was found to be (78 pg/mL) for the co-combination gel and (81 pg/mL) in the case of the control. Histopathologically, the co-combination gel heals wounds more quickly, compared to individual gel. These outcomes depict that a co-combination gel using plant extracts and drugs can be successfully used to treat burn injury.
