Waterborne plant viruses can destroy entire crops, leading not only to high financial losses but also food shortages. Potato virus Y (PVY) is the most important potato viral pathogen that affect other valuable crops. Recently, it has been confirmed this capable of infecting host plants via water, emphasizing relevance using proper strategies treat recycled water in order prevent spread infectious agents. Emerging environmentally friendly methods such as hydrodynamic cavitation (HC) provide a great alternative for treating used irrigation. In experiments conducted study, laboratory HC based on Venturi constriction with sample volume 1 L was samples spiked purified PVY virions. The ability infect abolished after 500 passes, corresponding 50 min treatment under pressure difference 7 bar. some cases, shorter treatments 125 or 250 passes were sufficient inactivation. disrupted integrity particles, which led minor damage RNA. Reactive species, including singlet oxygen, hydroxyl radicals, and hydrogen peroxide, primarily responsible inactivation during treatment, suggesting mechanical effects are likely driving force This pioneering first investigate eukaryotic by HC, will inspire additional research field enabling further improvement decontamination technology.
