7 CFR § 301.38-1 - Definitions.
In this subpart the following definitions apply:
Certificate. A document in which an inspector, or a person operating under a compliance agreement, affirms that a specified regulated article has met the criteria in § 301.38-5(b) of this subpart and may be moved interstate to any destination.
Clonally propagated. Reproduced asexually through cuttings, tissue culture, suckers, or crown division. For the purposes of this subpart, a Berberis plant will be considered clonally propagated only if its parent stock is, or was derived from, a seed-propagated black stem rust-resistant plant of more than 2 years' growth.
Compliance agreement. A written agreement between a State that is a protected area or that encompasses a protected area and a person who moves regulated articles interstate, or in a non-protected area between APHIS and such person, in which that person agrees to comply with this subpart.
Departmental permit. A document issued by the Administrator in which he or she affirms that interstate movement of the regulated article identified on the document is for scientific or experimental purposes, and that the regulated article is eligible for interstate movement under the conditions specified on the Departmental permit and found by the Administrator to be adequate to prevent the introduction of rust-susceptible varieties of the genera Berberis, Mahoberberis, and Mahonia into protected areas.
Limited permit. A document issued by an inspector to allow the interstate movement into or through a protected area of regulated articles not eligible for certification under this subpart to a specified destination outside the protected area.
Moved (movement, move). Shipped, offered to a common carrier for shipment, received for transportation or transported by a common carrier, or carried, transported, moved, or allowed to be moved. “Movement” and “move” shall be construed in accordance with this definition.
Person. Any association, company, corporation, firm, individual, joint stock company, partnership, society, or any other legal entity.
Rust-resistant plants. All plants of the genera Berberis, Mahoberberis, and Mahonia, and their progeny, that have proven resistant to black stem rust during testing by the United States Department of Agriculture, 2 and that are listed as rust-resistant under § 301.38-2 (a)(1) and (a)(2).
2 Testing is performed by the Agricultural Research Service of USDA as follows: In a greenhouse, the suspect plant, or test subject, is placed under a screen with a control plant, i.e., a known rust-susceptible variety of Berberis, Mahoberberis, or Mahonia. Infected wheat stems, a primary host of black stem rust, are placed on top of the screen. The plants are moistened and maintained in 100% humidity, causing the spores to swell and fall on the plants lying under the screen. The plants are then observed for 7 days at 20-80% relative humidity. This test procedure is repeated 12 times. If in all 12 tests, the rust-susceptible plant shows signs of infection after 7 days and the test plants do not, USDA will declare the test plant variety rust-resistant. The tests must be performed on new growth, just as the leaves are unfolding.
Two years' growth. The growth of a plant during all growing seasons of 2 successive calendar years.
