    light scab means that 1 to 5 per cent of the tuber surface is covered with common scab lesions; (gale légère)

    moderate Rhizoctonia

    moderate Rhizoctonia means that 5 to 10 per cent of the tuber surface is covered with Rhizoctonia sclerotia; (rhizoctonie modérée)

    moderate scab

    moderate scab means that 5 to 10 per cent of the tuber surface is covered with common scab lesions. (gale modérée)

  • (4) In any lot, the number of tubers that are affected by light and moderate scab and Rhizoctonia combined shall not exceed 10 per cent of the total number of tubers in the lot.

  • (5) [Repealed, SOR/2002-198, s. 4]

  • (6) The percentage of tubers found in a lot of any class that is of a variety other than the variety of which the lot generally consists shall not exceed the percentage permitted by sections 47.11 to 47.8 for that class.

  •  (1) An application by a grower for an inspection of a crop shall be made on a form provided by the Agency and shall include the following information and be accompanied by the following documents:

    • (a) seed potato tags or other documents that attest to the origin and class of each seed lot planted;

    • (b) a list of all of the grower’s crops;

    • (c) in the case of a crop that was planted with seed potatoes that were produced by the grower, information or documents that show that at least two field-grown lots from the grower’s farm unit have been subjected to laboratory tests and not found positive for the presence of Clavibacter michiganensis subsp. sepedonicus;

    • (d) in the case of a crop that was planted with Elite II, Elite III, Elite IV or Foundation seed potatoes that were not produced by the grower, information or documents that show that those seed potatoes have been subjected to laboratory tests and not found positive for Clavibacter michiganensis subsp. sepedonicus; and

    • (e) in the case of an application made by a new seed potato grower, a document, issued by an inspector, that verifies that a clean-up and disinfection of the premises at the grower’s farm unit was completed before the arrival of the seed potatoes for planting and that the crop was not planted in a field where non-certified potatoes were grown in either of the previous two years.

  • (2) The application shall be delivered to the office of the Agency specified on the form by the following deadlines:

    • (a) in the case of field-grown crops, on or before June 30 of the crop year in respect of which the application is made;

  • (3) An inspector shall not inspect a crop of a grower if

    • (a) in the current year,

      • (i) non-certified potatoes or Certified seed potatoes have been planted in fields under cultivation by the grower,

      • (ii) the crop is growing in a field where non-certified potatoes were planted in the previous two years, or

      • (iii) the crop is growing in a field where there has been an occurrence of bacterial ring rot, unless the inspector verifies that the field has been free of potatoes, including volunteers, for the previous two years; or

    • (b) in the previous year, potatoes infected with Clavibacter michiganensis subsp. sepedonicus were produced in fields under cultivation by the grower, or were found in buildings or on equipment used by the grower and a clean-up and disinfection of the building and equipment was not verified by an inspector.

    • (b) the distance between adjacent fields is less than the space required for one blank row;

    • (c) there are not at least 10 m of blank row at each end of the field to separate one class of a variety from another class of the same variety; or

    • (d) equipment used in relation to planting, cultivating or spraying the crop has been exposed to contamination by pathogens that are or may be detrimental to the crop, unless the equipment, each time before it has entered a field of a farm unit, has been thoroughly cleaned and disinfected in such a way as to destroy the contamination and the grower demonstrates to the inspector that the clean-up and disinfection has been completed.
