Sustainable Winegrowing with Vineyard Team

Beginning at version, grapes become a very attractive food for pest birds, particularly Sparrows and Starlings. Initially the vineyard is explored by small flocks of scouting birds. If those birds like the fruit, and if there is no obvious danger, the entire flock will follow. Falcons terrify pest birds, herding them away from the grapes, but not killing them.

Sustainability and certification are viewed as a “quality enhancement”. In the currently overly supplied market, sustainability is an advantage. A premium can be getting $200 to $300 more per ton of grapes in a good market or it can mean selling grapes when no one else can in a weak market. Gregg Hibbits, General Manager at Mesa Vineyard Management explains how their dedication to sustainability for over 30 years has drawn like-minded customers to their organization.

Brandi Moody explains that to develop a strong marketing strategy you need to know your consumer segments, learn about them, see what they like, and market to them where they are. Brandi is an experienced marketer with a keen sense of burgeoning trends, consumer insights, and brand storytelling.

We were already experiencing a market correction before COVID-19, so what can wineries do now and in the future to connect with their consumers and sell wines?

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”.

Wayne Wilxox, Professor Emeritus of Plant Pathology and Plant-Microbe Biology at Cornell University, spent his career on the applied biology and integrated management of grapevine fungal diseases. Wayne looks at berry susceptibility changes throughout the season to determine when control programs need to be maximized. Ultimately, his applied research sought to discover what makes a “disease tick” and use that knowledge to learn how to better target the disease.

Grape vine trunk diseases are prevalent in mature vineyards, shortening the vineyard’s life and productivity. Akif Eskalen, Cooperative Extension Specialist and Plant Pathologist at the Department of Plant Pathology at the University of California Davis, is researching naturally occurring microorganisms to use as biocontrol against these fungal pathogens.

One decade ago, amidst a limited labor supply and growing New Zealand wine industry, Klima co-founders Marcus Wichkam and Nigel George set out to solve their own labor issues with mechanization. By developing a highly efficient vineyard pruning system they have removed the physically demanding portion of the job opening the opportunity to employ fewer, more highly skilled tradesworkers to perform cane selection.

Lauren Noland-Hajik, Attorney and Lobbyist at Soares & Conway gives an update on new policies that affect the wine industry including the Water Resiliency Plan and how it affects Sustainable Groundwater Management Act; regulating power shutoffs to prevent wildfires; anticipated regulations on pesticides; and impending labor law changes.

John A. Roncoroni is the UC Cooperative Extension Weed Science Farm Advisor and UCIPM affiliate advisor in Napa County. In this podcast, John talks about his specialty; weed management in California’s Coastal and Foothill premium winegrape growing regions and why weeds should play a more important role in pest control programs.

In this special holiday edition we bring you a fascinating interview with Dr. Stephen Lloyd-Moffett, professor of Religious Studies at California Polytechnic State University. Stephen looks at the way in which passion for wine acts as a surrogate for religion: how it is used as a vehicle for communication, why rituals convey value, and how to use this beverage to create bonds.

Eric Herve, Research Scientist at ETS Laboratories and Matt Brain, Leader of the Sustainability Team at Crimson Wine Group and Associate Winemaker at Chamisal Vineyards, discuss how winemakers can screen grapes for the risk of smoke impact and work to mitigate its effects. Eric covers how impactful these compounds are at very low - parts per billion levels, the markers they are researching to test smoke exposure, blending considerations and much more.

Dr. Tara Sullivan is Assistant Professor of Soil Microbiology at Washington State University. In this interview, Tara discusses how the plant microbiome mirrors the human gut, the ways in which soil microorganisms can alter the bioavailability of micronutrients and metals for plants, why plants in alkaline soils can be deficient in iron when the soil is not, if cover crops can improve soil microbial communities, and what is next for her research.

Gerhard Pietersen is a plant virologist in South Africa. In this interview he discusses the severe plant health and economic impacts seen in S. Africa from Grapevine leafroll disease, the importance of regional buy in to establish control programs including a successful collaboration of 50 adjoining farms in New Zealand, and new techniques to detect the virus including loop-mediated isothermal amplification and grafting sensitive red cultivars on white cultivars to use the shoot as an indicator.

Dr. Scott Steinmaus is a professor, Biological Sciences at California Polytechnic State University in San Luis Obispo. His interview covers the complexities of herbicide resistance including challenges seen in glyphosate research around resistance, information bias, and environmental and social impacts. Scott highlights the importance of “mixing it up” – reducing use, preserving the limited modes of action available, and finding alternatives.
