Willamette Valley Vineyard, recently installed a special band of UV light called UVC light treatment, into their HVAC systems to protect their customers and employees from the coronavirus. Oregon Winemakers are now learning that UVC can be used to control powdery mildew in their vineyards.
Jim Bernau, founder of Willamette Valley Vineyard, decided to team up with the USDA, Oregon State University, Cornell and Washington State University to further study the benefits behind using UVC light and how it effectively kills powdery mildew when the fungus’ defenses are down at night.
