603-052-1200 Quarantine; Noxious Weeds (1) Establishing Quarantine. A quarantine is established against the noxious weeds listed herein. Noxious weeds have been declared a menace to the public welfare (ORS 569.180 and 569.350) because of the environmental and economic degradation that occurs when they become established. (2) Areas Under Quarantine. The entire State of Oregon and all other states of the United States and all foreign countries. (3) Covered Plants. For purposes of this rule the term "plants" applies to whole plants, plant parts, and seeds. This rule applies to all "A" and "B" state designated noxious weeds listed herein, except as provided in section (6). Plants on the Federal Noxious Weed List (7 C.F.R. 360.200) are also covered by this rule, with the exception of Japanese blood grass, Imperata cylindrica , var. Red Baron and Chinese water spinach, Ipomoea aquatica . (4) “A” weeds (a) "A" designated weeds. Weeds of known economic importance which occur in the state in small enough infestations to make exclusion, eradication, or containment possible; or which are not known to occur, but their presence in neighboring states makes future occurrence in Oregon seem imminent. (b) “A” weeds are controlled through exclusion, early detection, and rapid response (EDRR). Control of “A” weeds is a high priority for Oregon Department of Agriculture (ODA) and the primary goal is to prevent introduction and permanent establishment of “A” weeds. If “A” weeds are introduced, and eradication is not feasible, the secondary goal is to implement control measures to contain the “A” weeds to as small an area as possible so as to prevent widespread occurrence in Oregon. (c) When “A” weeds are detected, control actions are mandatory and the goal of such control is eradication. Any person owning or occupying property upon which “A” weeds are detected must contact the Oregon Department of Agriculture within 48 hours of detection. (d) Upon detection of “A” weeds, ODA may develop a survey, eradication, and monitoring plan to control or eradicate detected weeds. ODA may either develop and conduct appropriate measures to control or eradicate such weeds or may enter into a contract for the purpose of controlling or eradicating “A” weeds. (e) Control or eradication of “A” weeds may be implemented at no cost to a person owning or controlling land within this state upon which “A” weeds are detected. However, ODA may request any person owning or controlling land within this state to control, prevent the spread of, or eradicate where feasible “A” weeds, subject to supervision of such activities by the ODA. (f) If ODA or a county are unable to control or eradicate “A” weeds on private property, any person owning or controlling land within this state must control and take measures to eliminate or prevent the possibility of spread of “A” weeds to other lands and ownerships. Control measures for “A” weeds must be implemented in a timely manner as determined by ODA. Treatments must provide sufficient levels of control to make progress toward the goal of eradication. (g) ODA inspectors may access all lands within Oregon for the purpose of ORS 569.175 to 569.195 including carrying out the control or eradication of “A” weeds. (h) Any person owning or controlling land within this state found in violation of ORS 569.175 to 569.195 or these rules may be subject to fines up to the maximum for Class B violations.

Control of “B” weeds may vary according to ODA-established priorities as well as site-specific or case-by-case factors. When available, biological control may be the primary long-term control strategy. (b) The goal of “B” weed management is control and prevention of new infestations of “B” weeds in Oregon. ODA may advise persons owning or controlling lands upon which “B” weeds are detected on the control of “B” weeds on those lands as well as how to prevent “B” weeds from infesting new lands. As determined by ODA or a county, “B” weeds may be controlled or eradicated in the same manner as “A” weeds when “B” weeds appear in parts of the state where they were not previously detected or established. (c) Pursuant to ODA’s determination as to treatment of “B” weeds, ODA may develop a regional control plan or cooperate with a county, local entity, or persons owning or controlling private lands to develop and implement a plan to control “B” weeds. ODA may assist with implementing control measures. (d) Persons owning or controlling lands where “B” weeds are detected may request assistance from their respective local County Weed Inspector. (e) Cost-share assistance grants may be available for the control of State listed noxious weeds to any person owning or occupying land upon which “A” or “B” weeds are detected. If within a county weed control district or special weed control district the county may provide assistance by applying for cost-share assistance grants. Information on cost-share assistance grants may be found at ODA’s Plant Division website. (f) As determined by ODA, biological control agents may be available for some “B” weeds. Information on the current availability of biological control agents is provided on ODA’s Plant Division website. Releases of some biological control agents targeting noxious weeds may require reporting to ODA for tracking purposes.
