The bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most serious rice diseases, causing huge yield losses worldwide. Several technologies and approaches have been opted to reduce the damage; however, these have had limited success. Recently, scientists have been focusing their efforts on developing efficient and environmentally friendly nanobactericides for controlling bacterial diseases in rice fields. In the present study, a scanning electron microscope (SEM), transmission electron microscope (TEM), and a confocal laser scanning microscope (CLSM) were utilized to investigate the mode of actions of ginger EOs on the cell structure of Xoo. The ginger EOs caused the cells to grow abnormally, resulting in an irregular form with hollow layers, whereas the dimethylsulfoxide (DMSO) treatment showed a typical rod shape for the Xoo cell. Ginger EOs restricted the growth and production of biofilms by reducing the number of biofilms generated as indicated by CLSM. Due to the instability, poor solubility, and durability of ginger EOs, a nanoemulsions approach was used, and a glasshouse trial was performed to assess their efficacy on BLB disease control. The in vitro antibacterial activity of the developed nanobactericides was promising at different concentration (50–125 µL/mL) tested. The efficacy was concentration-dependent. There was significant antibacterial activity recorded at higher concentrations. A glasshouse trial revealed that developed nanobactericides managed to suppress BLB disease severity effectively. Treatment at a concentration of 125 μL/mL was the best based on the suppression of disease severity index, AUDPC value, disease reduction (DR), and protection index (PI). Furthermore, findings on plant growth, physiological features, and yield parameters were significantly enhanced compared to the positive control treatment. In conclusion, the results indicated that ginger essential oils loaded-nanoemulsions are a promising alternative to synthetic antibiotics in suppressing Xoo growth, regulating the BLB disease, and enhancing rice yield under a glasshouse trial.

“…The concentrations of esters were calculated using eqn (1): Based on the concentration of esters obtained, the number of moles of esters was determined. The percentage yield of esters was then further calculated by eqn (2). It is based on the assumption that 3 mol of red pitaya seed oil esters (RPSOE) will be produced from 1 mol of red pitaya seed oil (RPSO), as shown in eqn (3).…”

“…The isolation and purication of RPSOE were carried out according to the method of Gani et al (2011). 2 Aer removal of the enzyme from the mixture, n-hexane was then removed using a rotary vacuum evaporator at 68 C. RPSOE were puried by adding ethanol in a separation funnel in a ratio of RPSOE to ethanol of 1 : 3. In the alcoholysis reaction between RPSO and oleyl alcohol, the products are not only RPSOE but also glycerol.…”

“…Linoleic acid cannot be synthesized in the body; therefore, due to its health benets, it must be obtained in the diet or from topical application. 2 However, one weakness of the oil is oen associated with its oily feel. Meanwhile, oil esters have attracted the attention of industry over the last decade due to their non-greasiness, nontoxicity, good solubility properties and excellent emollient behavior, but without the oily feeling.…”
