The CEPB's sustainable viticulture research team has recently put out a new research brief: "Practice Adoption and Management Goals of Lodi Winegrape Growers". Read the full version by accessing the document below.

One priority of the Lodi Winegrape Commission (LWC), created in 1991 to serve the common interests of Lodi area winegrape growers, is to encourage the adoption of sustainability practices, or those practices that balance economic, environmental, and social costs and benefits, via research-based outreach and education. In this research brief we report results from a mail survey of winegrape growers in Lodi, CA that indicates whether or not growers are actually adopting sustainability practices, what impact the LWC has had on the adoption of these practices, and whether or not grower priorities reflect sustainability objectives in the first place.

The percentage of growers that regularly uses any given sustainability practice ranges widely from less than 10% (release beneficial insects) to over 90% (use visual observations to decide when to irrigate). Disease management is the most frequently adopted category of practices, due to direct economic benefits to growers. Growers who participate more in LWC outreach and education activities are also more likely to adopt sustainability practices. Growers prioritize financial objectives of vineyard management including winegrape quality, meeting winery expectations, winegrape quantity, and the profitability of their operation most highly while they prioritize environmental objectives such as promoting biodiversity and restoring wildlife habitat the least.
