Vineyard Practices

 

The Sonoma County Winegrape Commission provides ongoing targeted education on a variety of vineyard practices. Many of these meetings support the Code of Sustainable Winegrowing program. Grower meetings on topics like Integrated Pest Management (IPM), Sustainable Winegrowing Practices and water conservation are offered throughout the growing season. These informal meetings offer interaction with experienced growers, professional speakers and experts from UCCE and UC Davis. Meetings include grower-to-grower exchange of ideas and practical information including using biological controls in the vineyard, i.e. owl boxes, monitoring for the Glassy Winged Sharpshooters (GWSS), Vine Mealybug, European Grapevine Moth or the latest bug du jour, and providing various vineyard resources.
