Oregon Administrative Rules › Chapter 603 - DEPARTMENT OF AGRICULTURE › Division 52 - PEST AND DISEASE CONTROL › Section 603-052-1025 - Quarantine; Small Broomrape

Current through Register Vol. 63, No. 7, July 1, 2024
(1)
			 Establishing Quarantine. A quarantine is established to prevent the spread of
			 small broomrape, Orobanche minor, within Oregon and to protect markets for
			 Oregon seed crops. This quarantine is established under ORS
			 561.510 and
			 561.540 to protect Oregon's
			 agricultural industries from the artificial spread of small broomrape. Small
			 broomrape is not widely prevalent within or distributed throughout the state of
			 Oregon. Small broomrape is dangerous to Oregon's agricultural industries
			 because it parasitizes the root systems of host crop plants in the legume,
			 potato, carrot and sunflower families. Clover is the most susceptible host.
			 Damage includes direct yield losses, up to and including crop failure, as well
			 as possible market losses due to restrictions imposed by trading partners on
			 commodities potentially contaminated with small broomrape seed.
(2) Area under Quarantine: State of Oregon.
(3) Commodities Covered: Small
			 broomrape plants including seeds, clover (Trifolium pretense, T. repens, and T.
			 subterraneum) seed, and soil, commodities and equipment that may be
			 contaminated with small broomrape seeds.
(4) Provisions of the Quarantine:
(a) Imported red clover seed lots must have
			 been cleaned by a process that includes, at a minimum, the stages in
			 (4)(b)(A)-(C) below or an official seed sample must be taken and tested prior
			 to planting to ensure freedom from contamination by small broomrape seed.
			 Contaminated lots will be returned or destroyed without expense or indemnity
			 paid by the State.
(b) All red
			 clover seed lots harvested in counties west of the Cascade Mountains must be
			 cleaned by an approved process before transport, purchase, sale or offering for
			 sale. Approved cleaning processes must include, at a minimum, all the stages in
			 (A)-(C) below. Seed lots meeting this requirement need not be sampled and
			 tested for small broomrape contamination.
(A)
			 Air separator;
(B) Indent roller;
(C) Gravity separator.
(c) Alternative cleaning processes
			 may also be acceptable if approved by the Department. Cleaning facilities using
			 alternative processes must be under compliance agreement with the Department.
(d) The Department may take random
			 samples of finished red clover seed lots from cleaners meeting the requirements
			 of (b) or (c) above and test them for small broomrape. The cost of this random
			 sampling and testing will be born by the Department. If small broomrape is
			 found, cleaning of red clover seed will be curtailed until the cleaning process
			 is reviewed and problems corrected. All available clover seed lots from that
			 cleaner will be sampled and tested for small broomrape. Any infested lots will
			 be re-cleaned and released only after testing negative for small broomrape. The
			 costs of all follow-up sampling and testing after a positive find will be the
			 responsibility of the cleaner. The cleaner will be put under compliance
			 agreement before additional lots of red clover seed may be cleaned.
(e) Seed lots not meeting the cleaning
			 requirements outlined in (b) or (c) above must be officially sampled, tested
			 and found free of small broomrape seeds before transport, purchase, sale or
			 offering for sale. Upon request, Department inspectors will draw official seed
			 samples, which will be analyzed at a laboratory using a USDA-approved protocol
			 for small broomrape testing. Costs of sampling and testing will be the
			 responsibility of the grower or other responsible party. Contact: Market Access
			 and Certification Programs, Oregon Department of Agriculture, 635 Capitol St.
			 NE, Salem, OR 97301. Telephone: (503) 986-4620. Any seed lots found to contain
			 small broomrape seed are prohibited from transport, purchase, sale, or offering
			 for sale until they are re-cleaned, re-tested and determined to be free from
			 small broomrape.
(f) Screenings
			 from seed lots contaminated with small broomrape shall be disposed of in a
			 manner that will devitalize the seed or eliminate the risk of spread of the
			 weed such as pelletization, burning or burying.
