Sustainable Winegrowing

Will hybrid grapes help vineyards survive climate change? Professor Karine Pedneault of the Université du Québec en Outaouais explores this question through trials that expose grapevines to drought and heat stress. Testing both vinifera and hybrid varieties, her research measured plant water flow and metabolic responses to determine resilience. While hybrids still carry a stigma around flavor, they showed promising resistance, raising the potential to reduce fungicide use by up to half and adapt more sustainably to extreme weather scenarios.

With fungicide resistance on the rise, grape growers are looking for new ways to manage powdery mildew. Lexi McDaniel, Viticulture Extension Specialist at North Carolina State University, explores the science behind using UVC light to combat this grapevine disease by directly disrupting the DNA bonds needed for replication. She shares insights from her trials, including why the light must be applied at night, how often it needs to pass through the vineyard, and how this technique compares to traditional fungicide programs in both cost and effectiveness.

Terms like "regenerative," "climate‑smart," and "social equity" aren't just buzzwords—they're the building blocks of sustainable winegrowing. Learn wine brands protect soil, reduce energy use, and support people, all while producing high-quality wine.

Spotted lanternfly (SLF) is more than a nuisance, it poses a serious risk to vineyards. Brian Walsh, Extension Educator and Spotted Lanternfly Researcher with Penn State Extension, explains how this invasive insect threatens grapes across the eastern U.S. From unusual egg-laying behavior to honeydew-covered canopies that attract stinging insects, Walsh explores why vineyards are especially at risk and how growers can prepare during peak pressure in September. Learn about insecticide options, biocontrol efforts, and scouting strategies—whether SLF is in your area or not.
