Current through Register Vol. 63, No. 7, July 1, 2024
(1)
			 Establishing a Quarantine. A quarantine is established against the pest known
			 as cherry bark tortrix, Enarmonia formosana (Scopoli).
(2) Areas Under Quarantine. The entire state
			 of Washington, the province of British Columbia, and any other state, territory
			 or province where the presence of an established population of cherry bark
			 tortrix is confirmed and effective eradication procedures have not been
			 implemented, as determined by the Director of the Oregon Department of
			 Agriculture. In Oregon, Multnomah and Clackamas counties.
(3) Commodities Covered. The cherry bark
			 tortrix, Enarmonia formosana (Scopoli); host plants of the cherry bark tortrix,
			 including all species of the genera, Crataegus, Cydonia, Malus, Prunus,
			 Pyracantha, Pyrus and Sorbus; and unseasoned firewood derived from trees of
			 these host plant genera. Uninfested nursery stock plants of these genera that
			 are less than two inches in diameter are exempted from the
			 quarantine.
(4) Restrictions.
			 Regulated commodities shall not be shipped or moved directly or indirectly from
			 the regulated areas into the state of Oregon unless accompanied by a permit or
			 certificate issued by a state or federal agriculture official from the
			 regulated area and based upon the following conditions:
(a) The regulated plants have been grown in a
			 screened greenhouse or screenhouse adequate to exclude the adults of cherry
			 bark tortrix; or
(b) Such regulated
			 plants have been treated in accordance with a fumigation schedule approved in
			 writing by the Director of the Oregon Department of Agriculture; or
(c) Each dormant, defoliated, regulated host
			 plant shall be inspected by an authorized agricultural official of the
			 regulated state or province for the presence of cherry bark tortrix and found
			 free of any evidence of infestation by that pest;
(d) Portions of states or provinces listed in
			 the area under quarantine may have counties that are not infested with cherry
			 bark tortrix. Shipments of covered commodities may be accepted from these
			 noninfested counties if annual surveys are made in such counties and the
			 results of such surveys are negative for cherry bark tortrix. A list of
			 counties so approved will be maintained by the Oregon Department of
			 Agriculture. Agricultural officials of a quarantined state or province may
			 recommend a noninfested county be placed on the approved county list by writing
			 for such approval and giving the following information: areas surveyed, how the
			 survey was carried out, personnel involved and, if the county was previously
			 infested, date of last infestation. If heavy infestations occur in neighboring
			 counties, approval may be denied. To be maintained on the approved list, each
			 county must be reapproved every twelve (12) months. Shipments of and covered
			 commodities from noninfested counties will only be allowed entry into Oregon if
			 the uninfested county has been placed on the approved list prior to the arrival
			 of the shipment in Oregon.
