For more complete information on Washington\'s Agricultural Quarantines,
please consult the **Washington Plant Quarantine Manual** or request
copies of individual quarantines or summaries at the above address.

**NURSERY STOCK DEFINITION**

Horticultural plant includes, but is not limited to, any horticultural,
floricultural, and viticultural plant, for planting, propagation or
ornamentation growing or otherwise. The term does not apply to cut plant
material, except cuttings, budsticks, scion wood and similar plant parts
used for propagative purposes, or to olericultural plants.

**GENERAL SHIPPING REQUIREMENTS**

Each bundle, package or container of nursery stock shipped into
Washington State must be accompanied by a certificate (tag, label,
stamp, etc.) certifying that the plants are apparently free from plant
pests. Shipments must meet marking requirements set in rule.

**NOXIOUS WEED LIST**

Noxious weeds are non-native plants that have been introduced to
Washington through human actions. Because of their aggressive growth and
lack of natural enemies in the state, these species can be highly
destructive, competitive or difficult to control. These exotic species
can reduce crop yields, destroy native plant and animal habitat, damage
recreational opportunities, clog waterways, lower land values, and
poison humans and livestock.

To help protect the state's resources, the Washington State Noxious Weed
Control Board adopts a State Noxious Weed List each year. This list
categorizes weeds into three major classes - A, B, and C - according to
the seriousness of the threat they pose to the state or a region of the
state.

***Class A Weeds***

Class A weeds are non-native species with a limited distribution in
Washington. Preventing new infestations and eradicating existing
infestations is the highest priority.

***Class B Weeds***

Class B weeds are non-native species that are presently limited to
portions of the state. Class B species are designated for control in
regions where they are not yet widespread. Preventing infestations in
these areas is a high priority. In regions where a Class B species is
already abundant, control is decided at the local level, with
containment as the primary goal.
