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.

The biggest challenge in ag tech isn't innovation — it's making tools that actually work on the farm. Matthew Hoffman, General Partner and Head of Farms at Reservoir, shares how the company is helping ag tech startups develop tools that solve real farming challenges.
By partnering directly with specialty crop producers, including winegrape growers, Reservoir gives companies access to farms, equipment, and real-world feedback to refine technologies before they reach the market. Matthew highlights emerging innovations in autonomous equipment, robotics, machine vision, and farm management technology, and explains why grower involvement is essential to creating solutions that fit the realities of vineyard operations.
