PROCEDURES TO CONTROL BACTERIAL RING ROT

Every effort is made to prevent contamination of seed stocks by ring rot bacteria. The following mechanisms each contribute to the reduction of the risk of Bacterial Ring Rot:

Maintenance of pedigree records on all seed lots certified by the Canadian Food Inspection Agency. Records are maintained from generation to generation on all seed stocks produced in the province.

  • All seed potatoes produced originate from disease free nuclear stocks.
  • Limited field generation production system (flush-through production).
  • Inspections of the growing crop for Bacterial Ring Rot.
  • Tuber inspections at harvest or in the bin shortly after harvest.
  • Frequent tuber inspections at shipping point.
  • Seed trace backs on Bacterial Ring Rot occurrences in commercial potato production.
  • Laboratory testing of all seed lots for the presence of Bacterial Ring Rot.
  • Total rejection of all seed produced on a farm where a seed lot is determined to be infected with Bacterial Ring Rot.
  • Seed grower diligence in preventing Bacterial Ring Rot introduction which includes disinfecting all equipment and buildings involved in the harvesting, handling and storage of seed potatoes.
