Herbicide applications in Napa County
No applications have been published for Napa County yet. That means the county’s records have not been obtained and checked — not that nothing has been sprayed.
Pesticide use reports are requested from each county agricultural commissioner under the California Public Records Act and published here once they have been read and checked against their source documents. Napa County is on that list. If you already hold Napa County use reports, notices of intent or restricted materials permits, send them and they will be added.
