Sustainable Winegrowing With Vineyard Team

Weeds can compete with young vines and are hosts for some vineyard pests. Grant Cremers describes how he controls weeds through a combination of under-vine cultivation and herbicides at San Bernabe Vineyards. Topics include herbicide resistant weeds, reasons to avoid pre-emergent herbicides, cover crops for weed suppression, and the benefits of controlling weeds mechanically.

Dr. Timothy Miles discusses the prevalence of powdery mildew populations found to be resistant to FRAC group 11 fungicides. He then describes his work on finding the genes associated with resistance to FRAC group 11 fungicides and developing new molecular tools to identify fungicide resistant powdery mildew populations.

Three winegrape growers, Lucas Pope of Halter Ranch, Ryan Scott of Monterey Pacific, and John Pierini of J. Lohr Vineyards and Wines, share their specific, tried-and-true practices for preventing and managing Grapevine Trunk Diseases and the Red Blotch Virus. Topics include the logistics of pruning and dormant fungicide applications, trunk renewal, the economics of diseased vineyards, replanting, and the importance of virus-free plant material.

Grapevine Red Blotch-associated Virus causes a delay in ripening, unfavorable changes to juice chemistry, and lower yields in Chardonnay.   Dr. Deborah Golino is the Director of the Foundation Plant Services (FPS). FPS is a unit of the College of Agriculture and Environmental Sciences at UC Davis dedicated to the distribution of disease tested, true-to-identity plant materials produced by UC researchers or improved by technology developed by UC researchers. At this time, FPS is responsible for programs for grapes, strawberries, fruit trees, nut trees, sweet potatoes, and roses. These programs have played a key national and international role in distributing new crop varieties and healthy planting stocks.   Dr. Golino describes the history behind the discovery and study of the major grapevine virus diseases.   References: A Long and Winding Road: The Discovery of the Red Leaf Viruses, the Leaf Rolls and Red Blotch - Deborah Golino, Sustainable Ag Expo 2015 Presentation Foundation Plant Services Grapevine Red

Dr. Michelle Moyer, Assistant Professor and Statewide Viticulture Extension Specialist at Washington State University uses the age old fairytale of Goldilocks and the Three Bears to explain powdery mildew. Like Goldilocks, powdery mildew likes the weather conditions to be just right. Dr. Moyer explains these ideal conditions and two key ways to avoid disease in your vineyard by making things “not right”.   References: UC Davis Powdery Mildew Model UC Pest Management Guidelines Bunch Rot with Larry Bettiga   Listen to the latest science and research with the Sustainable Winegrowing Podcast.

Larry Bettiga is Viticulture Advisor for California’s Monterey, Santa Cruz and San Benito Counties. He discusses the life cycle of Botrytis cinerea (bunch rot) and how factors such as environment and canopy management in the vineyard affect the severity of the disease. Larry also describes the best management practices to prevent the development of fungicide resistance.   Resources: Bunch Rot Disease Management UC Pest Management Guidelines   Since 1994, the Vineyard Team has been your resource for workshops and field demonstrations, research, and events dedicated to the stewardship of our natural resources.
