The 2013 soil sampling campaign for Potato Cyst Nematodes (PCN) will begin as soon as local conditions are suitable. Annual PCN soil sampling and testing is mandatory for all seed potato fields with some production destined for export to the US, Mexico, or Thailand. Details are specified in the Canada and United Sates PCN Guidelines as well as in the specific import requirements for Mexico and Thailand. The required soil sampling will be conducted using a minimum of 2000 cc (approximately 5 pounds) of soil/acre.

Employees from local CFIA offices will distribute forms to all seed potato growers requesting that they identify the sites (fields) with production that will be shipped to the US, Mexico, or Thailand. Sites used to produce seed potatoes that will be sent to the US for post harvest test field grow-out should also be identified. Sites where production is not intended for export to the identified countries should not be identified for PCN soil sampling and testing.

If no soil samples have been collected from a production site, seed potatoes produced on that site will not be eligible for export to the US, Mexico, Thailand or for post harvest field grow-outs in the US. If growers wish to amend their list after their original submission they are encouraged to contact their local CFIA office as soon as possible and to identify any changes in writing.

This year, there will be two CFIA laboratories analysing PCN soil samples and the majority of samples will be sent to the laboratory in Charlottetown.  For additional details please see the table below. This initiative requires that a large number of soil samples be collected and tested on a priority basis based on the expected date of export provided by growers and included on the laboratory submission form. The expected date of export provided by growers must be as accurate as possible and should reflect the historic shipping practices of the farm unit in order for the CFIA to coordinate soil sampling and testing. Results for all soil samples collected from a farm unit must be available and negative for PCN before a phytosanitary certificate will be issued for seed potatoes destined to any country requiring annual PCN testing results.

For the 2013 PCN soil sampling campaign, please note that the CFIA will be phasing in user fees for collecting and analysing PCN samples for export certification of seed potatoes. For the 2013 crop year, the CFIA will charge half of the fees, a total of $49.87 per soil sample.

Soil sampling and analyses associated with investigating, monitoring and managing PCN regulated areas will continue to be exempt from fees.

For additional information on the 2013 PCN detection survey, please do not hesitate to contact your local CFIA office. We thank you in advance for your cooperation.
