Oregon Administrative Rules › Chapter 603 - DEPARTMENT OF AGRICULTURE › Division 52 - PEST AND DISEASE CONTROL › Section 603-052-0395 - Union County Potato Disease Control Area and Procedures

Current through Register Vol. 63, No. 7, July 1, 2024
(1) As authorized
			 by ORS 570.305 and
			 570.405, a control area is
			 established for the protection of the seed potato industry in Union County
			 against the introduction and spread of potato diseases, including viruses and
			 pests. Such area includes all of Union County, Oregon north of the Craig
			 Mountain Range: i.e. all of Union County north of a west to east line starting
			 at the intersection of the Western border of Union County and the northern
			 border of T4S R34E sec 34 and continuing due east to the eastern border of
			 Union County at the northern border of T4S R43E sec 31.
(2) The following methods are to be used in
			 the control area described in section (1) of this rule for the control of
			 potato diseases and pests within the control area and to prevent the
			 introduction of such diseases and pests into Union County:
(a) All potato seed imported into the control
			 area shall have a Federal-State Shipping Point inspection and certification
			 prior to entering the control area;
(b) All potatoes planted in the control area
			 for the purpose of producing seed quality or commercial potatoes shall meet the
			 minimum disease tolerances of OSU Potato Seed Certification Standards for
			 generation 2 (field year 3) stock and must be eligible for re-certification in
			 the growing area based upon a winter grow-out test. All production larger in
			 scope than a home garden (potatoes not grown for re-sale in commercial markets
			 are considered home garden or noncommercial potato production) must be entered
			 into the OSU Seed Certification Program as a seed production field or into the
			 Un-certified Field Inspection Program as a commercial production
			 field;
(c) All potato seed sold in
			 the control area for the purpose of home garden or noncommercial potato
			 production shall be of a quality that meets the minimum requirements of the
			 Oregon State University potato seed certification standards for Oregon G4 or
			 earlier generations;
(d) All cull
			 potatoes accumulated at the time potatoes are dug and moved into storage shall
			 be destroyed within 30 days, and all cull potatoes accumulated during shipment
			 process shall also be destroyed within 30 days;
(e) Diseases, such as potato late blight, or
			 viruses vectored by aphids require preventative management. Therefore,
			 appropriate control measures are required throughout the growing season to
			 prevent late blight infection or buildup of insects that vector viruses.
			 Specific ways to prevent these problems require using widely accepted methods
			 such as found in the Pacific Northwest Disease/Insect Management Handbooks, or
			 as recommended by local experts in disease/insect control.
(f) All farm equipment related to potato
			 production (used to till and level farm ground or handle potatoes), must be
			 steam cleaned or power washed to remove all soil and plant debris before
			 entering the control area.
