Current through Register Vol. 63, No. 7, July 1, 2024
(1) Establishing a quarantine. A quarantine
			 is established against
Rathayibacter toxicus
, the cause of
			 bacterial gummosis of seed heads. This quarantine is established under ORS
			 561.510 and
			 561.540 to protect Oregon's
			 agricultural industries and natural resources from the artificial spread of
R. toxicus
. This bacterium causes a disease that infects
			 ryegrass and other grass species, severely limiting seed production.
Rathayibacter toxicus
also produces a toxin that can
			 contaminate grass seeds, hay, and other plant parts; this toxin can be fatal to
			 mammals. Methods for exclusion of commodities potentially infected with this
			 disease and procedures for eradication of incipient infections are prescribed
			 in this quarantine.
(2) Area under
			 quarantine. All areas outside of the State of Oregon where
R.
			 toxicus
is known to occur and any property within the State of Oregon
			 where
R. toxicus
is detected;
(3) Commodities regulated. All plants and
			 plant parts including seed of the following regulated commodities: species of
			 grass known to be hosts for
Anguina
seed gall nematodes,
			 including
Lolium
species,
Dactylis
species,
			 and
Agrostis
species, and all known hosts of
R.
			 toxicus
, including
Phalaris
species,
Vulpia
			 myuros
(Rat's tail fescue),
Austrodanthonia caespitosa
			 (=Danthonia
caespitosa
, common wallaby-grass),
Avena sativa
(common oat), and
A. caespitosa
(
= Deschampia cespitosa
, tufted hairgrass). All life
			 stages of
R. toxicus
.
(4) Provisions of the quarantine. Regulated
			 commodities originating from the area under quarantine, and any other area
			 found to be infested with
R. toxicus
during the life of this
			 quarantine, are prohibited unless one of the following requirements has been
			 met:
(a) The regulated commodity originates
			 from an area that is free from
R. toxicus
based on official
			 surveys conducted by an official entity recognized by a National Plant
			 Protection Organization. The regulated commodity must be accompanied by an
			 official certificate that includes the following additional declaration: "The
			 shipment originates from an area known to be free from
Rathayibacter
			 toxicus
based on official survey." Official survey data supporting
			 this statement must be presented to the Oregon Department of Agriculture upon
			 request.
(b) The regulated
			 commodity has been tested in an official laboratory recognized by a National
			 Plant Protection Organization using a protocol approved by the Department and
			 has tested free from
R. toxicus
. The regulated commodity must
			 be accompanied by an official certificate that includes the following
			 additional declaration: "The shipment is free from
Rathayibacter
			 toxicus
based on official laboratory testing." An official laboratory
			 test report must be presented to the Oregon Department of Agriculture upon
			 request.
