We’ll begin with an overview of photocatalysis, where TiO₂ interacts with UV in daylight to produce reactive by-products that can quickly deactivate fungal and bacterial pathogens. Field research from 2025 will be highlighted, including applications on Vidal Blanc vines that significantly reduced downy mildew severity and sporulation when applied after rain events. Attendees will also learn how this approach compares to standard organic treatments.
The session will also examine the role of artificial UV-C light as a standalone disease management tool across a range of crops. We’ll discuss how UV-C can be used to suppress pathogens, and where research is heading for broader agricultural applications.
Practical guidance will cover application methods, including mixing and spray techniques, timing considerations for maximum effectiveness, and key factors such as concentration rates and potential risks of overapplication. Safety considerations, current regulatory status, and real-world cost comparisons will also be addressed to help growers evaluate feasibility.
Attendees will leave with a clearer understanding of how TiO₂ and UV-C technologies work, where they show the most promise, and what questions remain as research continues to evolve.
Key Topics Include:
- How TiO₂ and UV light work together to control plant pathogens
- 2025 research results on managing grape downy mildew
- The role of UV-C light in crop disease suppression
- Application timing, methods, and concentration considerations
- Benefits, limitations, and potential risks
- Cost comparison with conventional and organic treatments
- Safety practices and current regulatory landscape
