In Episode 72 of the Vineyard Underground podcast, host Fritz Westover sits down with Dr. Katie Gold, Assistant Professor of Grape Pathology at Cornell University, to delve into the pivotal role of research in shaping effective vineyard spray programs. Dr. Gold’s expertise in grape disease management offers listeners a comprehensive look at how scientific findings translate into practical strategies for vineyard health.
The Science Behind Spray Decisions
Dr. Gold emphasizes the importance of moving beyond traditional calendar-based spraying methods. Instead, she advocates for the adoption of disease forecasting models that consider real-time weather data and pathogen biology. These models enable growers to make informed decisions, optimize fungicide applications, and reduce unnecessary chemical use.
One key insight from the discussion is the concept of “decision support systems,” which integrate various data sources to predict disease risk. By leveraging these tools, growers can anticipate disease outbreaks and apply treatments proactively, rather than reactively.
Addressing Fungicide Resistance
A significant portion of the conversation centers on fungicide resistance — a growing concern in vineyard management. Dr. Gold explains how over-reliance on specific fungicides can lead to resistant pathogen strains. She underscores the necessity of rotating fungicide modes of action and incorporating integrated pest management practices to mitigate this risk.
Bridging Research and Practice
Dr. Gold also highlights the gap between academic research and on-the-ground vineyard practices. She stresses the importance of effective communication and extension services to ensure that scientific advancements reach growers in a usable form. By fostering collaboration between researchers and practitioners, the industry can collectively enhance disease management strategies.
Final Thoughts
This episode offers valuable insights for vineyard owners and operators seeking to refine their spray programs through evidence-based approaches. Dr. Gold’s expertise illuminates the path toward more sustainable and effective disease management, emphasizing the critical role of research in everyday vineyard decisions.
