Pest Exclusions

Agriculture Weights and Measures Banner 750

This provides protection to the county by regulatory control through quarantines to prevent the introduction of pests that are not known to exist or are of very limited distribution in the county. Incoming plant material is inspected for pests at various locations, such as nurseries, parcel centers and landscape planting sites. To facilitate the shipment of agricultural products out of Sonoma County, phytosanitary certificates are issued for agricultural commodities, which have been inspected for pests and diseases and verified to meet the plant quarantine requirements of the receiving county, state, or country.

Sudden Oak Death (SOD)

Sudden Oak Death is a fungus-like organism that affects a wide variety of plants such as coast live oak (Quercus agrifolia), redwood (Sequoia sempervirens), rhododendron sp., camellia sp., bay laurel (Umbellularia californica), Douglas fir (Pseudotsuga menziesii), western starflower (Trientalis latifolia), madrone (Arbutus menziesii). Sonoma County is generally infested with the disease, and it is primarily found in the native woodland and rural areas within the county. Our office is responsible for helping to prevent the artificial movement of the disease out of the regulated area. Anyone moving host plant material outside of the regulated area must contact our office to have the plants inspected and certified prior to shipment.
