Air Quality

Protecting air quality in Napa Valley is crucial for the health of the environment, the well-being of workers, and the overall quality of the grapes and wine produced. As responsible farmers, we should pursue practices that complement and protect our unique environment and natural resources, here are a few ways growers can work to protect air quality:

​​​Adopt Low Smoke Burning Methods: NVG's Vineyard Burning Task Force developed a 6-step approach to help preserve air quality by significantly reducing the amount of smoke generated in Napa County due to agricultural burns. The result is a virtually smoke-free burn. 

Use Integrated Pest Management (IPM): Use IPM techniques to minimize the use of chemical pesticides. This approach involves monitoring and managing pests through a combination of biological, cultural, physical, and chemical controls. ​​​

Understand Proper Pesticide Application: If pesticides are necessary, apply them during conditions that minimize drift, such as when there is low wind and stable atmospheric conditions. Use precision application equipment to target specific areas and reduce overspray.

​Plant Cover Crops: Planting cover crops between rows helps reduce soil erosion and dust. These cover crops can also help improve soil health and reduce the need for synthetic fertilizers. 

​Comply with Regulations: Comply with local, state, and federal regulations related to air quality and agricultural practices. Stay informed about any updates or changes to regulations that may affect vineyard operations.
