“…The phenolic compounds, flavonoids, produced in response to pathogen's attack, coagulate bacterial proteins and enzymes of vital pathways (Al-Obaidi 2014). The anti-microbial action of these bioactive plant compounds is, however, dose-and pathogen-contact dependent (Regnault-Roger et al 2005;Naz et al 2015b;Khan et al 2019b). In our studies, the doses and amounts in soil amended with plant powder are most likely much lower than when pure substances are considered.…”

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.

“…This technique was used successfully for the control of R. solanacearum both in vivo and in vitro. Soil amendment with dried powder or green manure of different medicinal plants or weeds such as Withania coagulans, W. somnifera, Xanthium strumarium resulted in significant reduction in bacterial wilt disease in tomato plants [16][17][18]. Their aqueous extracts effectively inhibited the growth of R. solanacearum which indicates the presence of antibacterial compounds in these plants.…”

Bacterial wilt disease caused by Ralstonia solanacearum is a devastating plant disease that inflicts heavy losses to the large number of economic host plants it infects. The potential of dried powder of the Conyza canadensis to control bacterial wilt (BW) of tomato was explored in vitro and in planta. Three application times (16 days before transplanting (DBT), 8 DBT and 0 DBT), three plastic-mulch durations (10 days plastic mulching (DPM), 5DPM and 0DPM) and four doses viz. 0 g, 8 g, 16 g and 24 g of the plant powder were evaluated. SEM analysis was also conducted to observe the change in bacterial cell morphology. Ethanol extract of dried C. canadensis in different concentrations inhibited the in vitro growth of R. solanacearum by as much as 98% of that produced by ampicillin. As evident from the scanning electron micrograph, the highest concentration produced severe morphologic changes, such as rupture of the bacterial cell walls and cell contents leaked out. Results from application time and dose experiment demonstrated that the highest powder dose viz. 24 g kg−1 mixed with infested soil 16 DBT gave maximum root length (34.0 ± 2.5 cm), plant height (74.3 ± 4.7 cm), fresh biomass (58.3 ± 4.3 g), reduction in bacterial population (1.52 log10) and resulted in lowest AUDPC value (1156.6). In case of mulching duration and dose experiment the maximum root length (39.6 ± 3.2 cm), plant height (78.3 ± 5.8 cm), fresh biomass (65.6 ± 4.9 g) reduction in bacterial population (1.59 log10) and lowest AUDPC value (1251.6) was achieved through the application of highest powder dose viz. 24 g kg−1 and longest plastic mulching duration of 10 DPM. The better results of highest dose and longer application time can be explained on the basis of higher amounts of anti-microbial plant bio-active compounds in highest dose and the longer exposure time of the pathogen to these chemicals. The better results of longer mulching duration are due to faster and more complete decomposition (because of 10-days-long plastic-mulch-provided increased solar heat) of the dried powder which produced more amounts of volatile and non-volatile bactericidal compounds. Our results clearly suggest that the use of 24 g kg−1 dried plant powder of C. canadensis plastic-mulched for two weeks could be used as a reliable component of the integrated disease management program against BW.
