304: Vineyard Mothballing: Costs, Risks, and Long-Term Yield Consequences

With current market shifts, vineyard mothballing can buy growers time—but it requires strategy, not abandonment. Chris Chen, Integrated Vineyard Systems Advisor with UC Cooperative Extension, draws on research in Australia and field experience in California to outline what minimal management really looks like. From pruning approaches and livestock integration to pest and disease management, irrigation by rootstock and soil type, and long-term yield risks, he explains how to reduce costs now without compromising a vineyard's future—or risking fines.  Resources:   4/8/2026 REGISTER: Tailgate | Mothballing Roundtable Chris Chen - Twitter Out of Sync: vineyard responses to changing conditions  Partial Solar Radiation Exclusion with Color Shade Nets Reduces the Degradation of Organic Acids and Flavonoids of Grape Berry (Vitis vinifera L.)

Lasers may offer a chemical-free way to deter bird pests in vineyards and other agricultural systems.  George Gallagher, Department Head of Animal Science at Cal Poly San Luis Obispo, explains why bird pressure goes beyond crop loss, raising concerns about disease risks like salmonella, E. coli, and transmission of avian influenza. He shares results from a controlled study using a handheld laser, aimed at birds' feet, to measure how long it took them to respond.  The research showed that different birds react differently. George highlights the importance of animal safety and the role of species-specific vision when evaluating new deterrent tools.
