320: How Grapevine Rootstocks Affect Drought Tolerance, Yield, and Canopy Growth
2026/07/16 | 36 mins.Choosing the right grapevine rootstock can improve drought resilience without sacrificing yield. Patty Skinkis, Viticulture Extension Specialist and Professor in the Horticulture Department at Oregon State University, shares findings from long-term Oregon rootstock trial comparing mature and young vineyards.
Learn which rootstocks produced larger canopies and higher yields with less water stress, why traditional low-vigor choices may struggle in no-till systems, and how this research is shaping an updated guide to help growers select rootstocks for climate resilience, vineyard establishment, and future production.

In this episode, David Eissenstat, Professor Emeritus at Penn State University, explains how decades of root research have challenged the myth that roots only grow at bloom and after harvest.
He shares how underground research techniques reveal the hidden life of grapevine roots, why young roots drive water and nutrient uptake, how root growth changes with temperature and moisture, and what growers should know about managing vineyards with a deeper understanding of root biology.

Vineyard Team Membership - Connect with a community advancing sustainable winegrowing - Three-cornered alfalfa hopper (TCAH) is the only confirmed insect vector of grapevine red blotch virus in Vitis vinifera, yet many growers first realize they have the pest only after spotting petiole girdling in the vineyard. Cindy Kron, North Coast IPM Advisor at UC ANR, shares findings from two years of weekly sweep-net monitoring at Oakville Research Station that revealed TCAH adults are present well before bud break, suggesting grapevines are not their preferred host.
She explains the insect's life stages, why legumes serve as key feeding and reproductive hosts, and why detecting early instars remains a major challenge for vineyard IPM. Cindy also discusses how degree-day models may help growers better time tillage to reduce TCAH populations and limit grapevine red blotch risk.
