The recent advances in nanotechnology and its use in the field of agriculture are astonishingly increasing; therefore, it is important to understand their role in plant life. Four wheat cultivars soaked in different concentrations of TiO2-NPs (0.0%, 0.025 %, 0.05 %, 0.1 %, 0.2 % and 0.5 %) to select a concentration that stimulate cultivars growth under normal conditions during germination stage. Cultivar dependency appeared markedly in their response to TiO2-NPs. Generally, TiO2-NPs did not modify germination percentage, despite 0.1 % TiO2-NPs vastly enhanced seed potential by increasing vigor index, root dry matter stress tolerance index, shoot dry matter stress tolerance index, dry matter stress tolerance index, plant height stress tolerance index, root length stress tolerance index, fresh matter stress tolerance index and pigment composition. The surrounding concentrations exert little effect on the studied parameters and 0.5 % TiO2-NPs suppressed all indices.

In this study, foliar sprays of Fenton solutions (Fenton reaction, Fenton-like reaction and Fenton complex), titanium dioxide (TiO2) and the recommended fungicide (chlorothalonil) were estimated in the control of sugar beet leaf spot caused by Cercospora beticola under field conditions in two growing seasons. In addition, the impacts of these treatments on some crop characters (leaf dry weight, root fresh weight, soluble solid content, sucrose content and purity of sugar) were examined. Biochemical and histological changes in the livers and kidneys of treated rats compared to an untreated control were utilized to assess the toxicity of the examined curative agents. Overall, chlorothalonil and Fenton complex were the most effective treatments for disease suppression in both tested seasons followed by Fenton-like reagent, Fenton’s reagent and TiO2, respectively. Growth and yield characters of treated sugar beet significantly increased in comparison to an untreated control. There were mild or no (biochemical and histological) changes in the livers and kidneys of treated rats compared to the control. Fenton solutions and TiO2 may offer a new alternative for leaf spot control in sugar beet.

The aim of this study was to determine and compare the antimicrobial activity of UV radiation of wavelength 253.7 nm (used in typical germicidal lamps) against Salmonella Enteritidis on the surfaces of conventionally produced white ceramic wall tiles (matt and shiny) and the same tiles coated with TiO₂, using three different methods: rf diode sputtering, atmospheric pressure chemical vapour deposition (APCVD), and spray pyrolysis deposition (SPD). Results clearly indicate that the bactericidal action of UV radiation is much stronger on the surfaces of tiles coated with TiO₂ than on the tiles uncovered. The strongest bactericidal effects of UV radiation was found for film prepared by APCVD, weaker for sputtering, and the weakest for SPD. Results of experiments for shiny and matt tiles did not differ statistically.
