Wash. Admin. Code § 16-462-027 - Virus sampling and testing requirements for registered (G2/G3) grapevines
(1) In addition
to required visual inspections, all registered (G2/G3) grapevines may be tested
by the department for regionally occurring viruses regulated under this
chapter, on a five-year rotation. Regionally occurring viruses are those that
can be vectored within the registered block. Pests to be tested for will be
recommended annually by consensus of an agency recognized industry stakeholder
group with representation for the Pacific Northwest region.
(2) Testing will be prioritized as follows:
(a) All vines showing symptoms upon visual
inspection by the department will be tested immediately.
(b) Vines of varieties with the highest
distribution by the nursery.
(c)
Vines of varieties considered unlikely to show visual symptoms of virus shall
be sampled and tested at twenty percent per year, or as directed by the
department.
(d) Other vines not
described above.
(3) The
department and entities authorized by the department will test registered G2
grapevines by methods consistent with those utilized by the Clean Plant Center
Northwest.
