Fusarium wilt is one of the most damaging fungal diseases of plants in the world, causing significant yield loss. Control measures such as cultural, biological, physical and chemical methods have their limitations. Hence, there is a need to explore nanotechnology, a field of science concerned with the manipulation of nanoparticles (NPs), which has found widespread application in different fields. The in vivo study results revealed that the tomato plants treated with magnesium oxide (MgO) nanoparticles had better growth performance with higher chlorophyll content (4.63 mg/L) compared to the control (0.67 mg/L) after 30 days of post-inoculation (DPI). Compared to the untreated control, tomato plants treated with magnesium oxide nanoparticles had a significant decrease in the percentage disease incidence, with 10% in tomato plants treated with MgO nanoparticles and 100% in the untreated control, respectively, after 30 days of post-inoculation. The research has demonstrated that the Fusarium wilt disease of tomato plants can be controlled using MgO nanoparticles.
