“…The use of bactericidal agents is desirable and preferred, since killing the bacteria allows the infection to be eliminated, and most importantly, minimizes the possible emergence of resistance and the spread of infections; in this sense, L. tridentata represents a promising alternative treatment for phytopathogenic bacteria [8,67].…”

Due to the emergence of bacterial resistance in phytopathogenic microorganisms, it is necessary to search for new treatment alternatives for these pathogens. Natural extracts are a potential source of bioactive compounds that can act against such bacterial strains. The antibacterial activity of Larrea tridentata against bacteria with public health importance has been documented; however, few reports cover pathogens associated with the agricultural sector. The aim of the present study was to evaluate the antibacterial activity of Larrea tridentata hydroalcoholic extract (LTHE) and fractions against phytopathogenic bacteria. LTHE was obtained by the maceration technique and then subjected to bipartition using solvents of different polarities. Clavibacter michiganensis sbsp. michiganensis, Pseudomonas syringae, and Xanthomonas campestris strains were used, and their antibiotic sensitivity was determined. The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of LTHE and its fractions (aqueous: LTAq-F; organic: LTEtOAc-F) were determined. LTHE and its organic fraction showed bactericidal activity against the three bacteria, showing better activity against X. campestris, exhibiting an MIC of 0.39 mg/mL and an MBC of 0.78 mg/mL. The results show that LTHE and its organic fraction have bactericidal activity in vitro against Clavibacter michiganensis sbsp. michiganensis, Pseudomonas syringae, and Xanthomonas campestris.

Nanoparticles in inhibiting Pantoea ananatis and to control maize white spot

et al. 2022

Maize white spot (MWS) caused by Pantoea ananatis is one main maize leaf diseases, and nanoparticles (NPs) are an innovative approach for bacterial disease control. This research evaluated the toxicity of pure NPs and doped NPs with different elements in inhibiting bacterial growth and to control MWS. Pure NPs and ZnO NPs doped with silver (Ag), gold (Au), copper (Cu), iron (Fe), manganese (Mn), and nickel (Ni) at different concentrations were used to determine the toxicity for P. ananatis in vitro, evaluating the bacterial growth inhibition zone. To assess the control of MWS, in the preventive application, maize plants were sprayed with NPs of ZnO:0.1Cu, ZnO:0.05Fe, ZnO:0.2Mn and ZnO:0.7Ni at 10, 5 or 2.5 mg mL-1, and after 3 days, the plants were inoculated with bacterial suspension. To assess the curative application, plants were inoculated with the bacteria, and 3 days later sprayed with the NPs. The disease severity was assessed and the area under the disease-progress curve (AUDPC) was calculated. The doped ZnO NPs with different elements, and at different concentrations inhibited bacterial growth in vitro. NPs of ZnO:0.1Cu and ZnO:0.2Mn at 5 or 2.5 mg mL-1, in both applications reduced the severity of MWS, showing potential for use in the disease management.

“…Biogenic silver nanoparticles (AgNPs) have been given significant attention due to their unique biological, physico-chemical, and antimicrobial activity properties in controlling plant pathogens [20,21]. Various studies have been reported that AgNPs are able to suppress many bacterial phytopathogens, such as Acidovorax oryzae strain RS-2 [22], Clavibacter michiganensis subspecies michiganensis [23], and Pseudomonas syringae pv. tomato DC 3000 [24].…”

Silver Nanoparticles Synthesized by Using Bacillus cereus SZT1 Ameliorated the Damage of Bacterial Leaf Blight Pathogen in Rice

et al. 2020

Amongst serious biotic factors deteriorating crop yield, the most destructive pathogen of rice is Xanthomonas oryzae pv. oryzae (Xoo), which causes bacterial leaf blight (BLB) disease. This study involved targeted use of biogenic silver nanoparticles (AgNPs) to control BLB in order to cope with the disadvantages of chemical disease control. AgNPs were biologically synthesized from natively isolated Bacillus cereus strain SZT1, which was identified through 16S rRNA gene sequence analysis. Synthesis of AgNPs in bacterial culture supernatant was confirmed through UV-VIS spectroscopy. Fourier transform infrared spectroscopy (FTIR) confirmed that the existence of AgNPs was stabilized with proteins and alcoholic groups. X-ray diffraction (XRD) data revealed the crystalline nature and imaging with scanning electron microscopy (SEM) and transmission electron microscopy (TEM), showing the spherical shape of AgNPs with particle sizes ranging from 18 to 39 nm. The silver presence in AgNPs was further confirmed by energy dispersive spectra. Biogenic AgNPs showed substantial antibacterial activity (24.21 ± 1.01 mm) for Xoo. In a pot experiment, AgNPs were found to be effective weapons for BLB by significantly increasing the plant biomass with a decreased cellular concentration of reactive oxygen species and increased concentration of antioxidant enzyme activity.
