Amazing achievements resulted from this nanotechnology including all agricultural fields such as plant nutrition and crop productivity, energy sector, food sector, and plant biotechnology. A conjugation between plant biotechnology and nanotechnology has been produced an important science called plant bio-nanotechnology. Several fields have been invaded through different nanobiotechnology applications in agriculture including (1) the nanotechnology of encapsulated agro-chemicals, (2) the monitoring of different environmental stresses and crop conditions using nanobiosensors, (3) the improvement of crop production and ameliorating plants against diseases and (4) solution several environmental problems. The crop productivity also could be improved using some new agro-chemicals (e.g., nanofertilizers and nanopesticides). These agro-chemicals are very effective in delivering encapsulating nanomaterials and then enhancement the productivity of crops as well as the suppress plant pests and diseases and protecting the environment from pollution. On the other hand, nanoparticles could enter the food chain via different nano-agrochemicals or nano-processed foods. Therefore, many approaches including uptake of nanoparticles by plants, entry and bio-distribution of nanoparticles into the food chain are needed before using of different bionanotechnological tools in agro-production sector. Further new regulations should be created or re-built for new approaches in plant bionanotechnology.

Variable levels of rust infection followed by a significant reduction in grain weight were recorded at both locations. Stripe rust infections for Sids location (20S - 90S) were higher than those of Sakha location (TrMS - 70S). Average coefficient of infection (ACI) and grain weight loss for Sids location, reaching 90 ACI (Gemmeiza-11) and 23.12% (Giza-160), were higher than those of Sakha location up to 70 ACI and 16.72% in Giza-160. Grain weight loss was strongly associated with ACI among cultivars for both locations, recording r=0.9044 for Sakha location and r=0.8866 for Sids location. Climatic variations were recorded at both locations during the first four months of 2017 and 2018. Rainfall and relative humidity for Sakha location were higher than those of Sids location while wind speed for Sids location was higher than that of Sakha location. Temperatures were relatively close at both locations. ACI values for Sids location were higher than those of Sakha location, revealing correlation with climatic factors. This suggests that wind speed may play an important role in dispersal while relatively heavy rainfall may have opposing effects. The temperature was the main limiting factor for stripe rust infection (negatively associated), followed by relative humidity (positively associated).

On the other hand, Peppermint oil recorded the highest reduction in radial growth of pathogen followed by Basil oil while Marjoram oil had no effect on the growth of pathogen. The green house experiment showed that, most treatments were efficient in pathogenicity reduction but the microbial treatment exhibited an advantage over essential oil where growth and yield parameters were sharply improved.
