Potato Wart Update

Provided by National Potato Council - April 13, 2001

  • The USDA-APHIS continues to handle the potato wart issue on a scientific basis despite efforts by Canada to politicize the issue. USDA has presented Canada with a 3-year protocol based upon currently available scientific data on the potato wart. The Agency is also continuing to try to learn more about the disease. In an April 10 letter to Robert Carberry, the Canadian Director of Plant Health, APHIS has suggested some adjustments in the protocol regarding seed and tablestock shipments from PEI to other parts of Canada. The new adjustment proposed is as follows:

    1. Seed potatoes from Zone 3 could be moved to other provinces of Canada under normal seed certification procedures, a phytosanitary inspection at the shipping point, and testing for potato wart sporangia on residual soil generated from the packing process. This proposal is contingent on CFIA's providing the following information to APHIS; the acreage of seed potato lots in Zone 3, the estimated volume of seed potatoes produced in Zone 3, the projected volume of seed potatoes produced in Zone 3 that will be moved to other provinces of Canada, the varieties of seed potatoes produced in Zone 3, and the PEI Seed Directory.

    2. Tablestock potatoes originating in Zone 3 could be moved to all provinces of Canada in consumer packs of 50 pounds or less.

    3. Bulk potatoes from Zones 3 and destined for processing facilities in other provisions of Canada would not need to be washed prior to shipping. I n addition to the mitigation measures set forth in the letter of March 19, 2001, a processing facility operating under a CFIA compliance agreement also indicated that any shipment of potatoes rejected at the processing facility shall be returned to PEI for disposal. CFIA must ensure that a method of tracking the disposal of these rejected shipments is in place.

    4. Latest Development - Canadian Ag Minister Vanclief in a public announcement before over 400 PEI farmers yesterday totally misrepresented the above condition on tablestock potatoes that could be shipped within Canada. He and PEI Ag Minister Mitch Murphy told growers they could ship tablestock potatoes from zones 3 & 4 unwashed and not sprout inhibited to the other provinces. That is not true and was not even discussed in the Dunkle letter sent to Carberry yesterday. The reason this is so important on PEI is that over 200 growers do not have the capacity to wash or sprout inhibit. Dave Lavway has been in constant contact with APHIS and has been assured the U.S. Border is closed and will stay closed until Canada responds in writing outlining how they intend to comply with all the conditions. Once the PEI growers find out the truth, the repercussions will be huge on the Island. You will see and hear a great deal of misinformation that is in the Canadian press. You can be sure the NPC is on top of the issue and will continue to monitor how this latest situation turns out.
