ATCP 21.14(4) (4) Sale or processing of table stock potatoes.

ATCP 21.14(4)(a) (a) No table stock potatoes may be marketed unless free from any visible evidence of infection by the potato rot nematode.

ATCP 21.14(4)(b) (b) Potatoes from an infested field or warehouse where infected potatoes are found that have been randomly inspected by the department and show no visible evidence of infection may be marketed or shipped for grading or processing for food purposes provided adequate safeguards are taken to prevent the spread of the disease during transit, grading, or processing. Potatoes showing evidence of infection and all cull and waste material resulting from the inspection, grading, or processing of the potatoes shall be destroyed or disposed of in a manner which prevents spread of the disease.

ATCP 21.14(4)(c) (c) No potatoes from an infested field may be delivered to another state without written approval of the department and the responsible plant pest control authority in that other state.

ATCP 21.14(5) (5) Sale as certified seed.

The department may grant approval if, in the judgment of the department and the college, the infestation has been thoroughly eliminated and a disease hazard no longer exists.

ATCP 21.14(5)(b) (b) Potatoes grown on adjacent or exposed fields may be certified and sold for seed purposes only with written approval of the department. Approval shall not be granted if, in the judgment of the department and the college, the fields may be infested or there is a danger that the disease may spread.

ATCP 21.14(5)(c) (c) If potatoes infected with potato rot nematode are found in any warehouse, no potatoes from that warehouse may be certified or sold for seed purposes except with the approval of the department and the college.

ATCP 21.14(5)(c)1. 1. The potatoes were cultivated, harvested, and stored in a manner which minimizes the spread of potato rot nematode.

ATCP 21.14(5)(c)2. 2. The potatoes were not stored in the same bin with potatoes infected with potato rot nematode.

ATCP 21.14(5)(c)3. 3. The warehouse and storage bins are constructed, maintained, and operated in a manner which effectively precludes the spread of potato rot nematode between bins.

ATCP 21.14(5)(c)4. 4. There is minimal risk that the certification or sale of the potatoes will result in the spread of potato rot nematode.

ATCP 21.14(5)(d) (d) If a warehouse is found to contain potatoes infected with potato rot nematode, certified seed potatoes shall not be stored in that warehouse until all potatoes are removed from the warehouse and the warehouse is thoroughly cleaned and disinfected under the supervision of the college.
