Blueberry scorch virus.

Blueberry scorch virus is an aphid-borne virus that causes necrosis of leaves and flowers in susceptible blueberry varieties, leading to a decline in productivity. A strain of blueberry scorch virus benign to varieties commonly grown in the Pacific Northwest has been historically present in Washington. Now a more virulent strain of blueberry scorch virus has been identified in western North America. If this virulent strain is introduced into the state, it will have a severe economic impact on Washington's blueberry industry. The strains of blueberry scorch virus cannot be readily distinguished by standard laboratory testing methods, making it necessary to eliminate all strains of this virus from Washington. A quarantine is established under authority of chapters 17.24 and 15.13 RCW, in order to prevent introduction and spread of all strains of blueberry scorch virus.

(b) They are certified in accordance with the regulations of an official certification program in the state of origin that includes testing and inspection for blueberry viruses and is approved by the director;
(c) They are shown to be free of blueberry scorch virus, based on an official laboratory test using a protocol approved by the director; or
(d) They are micropropagated and/or grown in an insect-proof greenhouse or screenhouse and originate from mother plants that have been tested and found free of blueberry scorch virus.
(2) Persons importing regulated articles into the state must obtain a phytosanitary certificate from the plant protection organization of the place of origin verifying that one of the conditions in subsection (1) of this section has been met. A copy of the phytosanitary certificate must accompany the shipment.
