Prince Edward Island Potatoes Prince Edward Island Potatoes Prince Edward Island Potatoes (also known as PEI Potatoes) refers to the brand and geographic identifier for potatoes grown and packaged in Prince Edward Island, a Maritime Province on the Atlantic coast of Canada. In a similar fashion to potatoes grown in other parts of North America (such as Idaho), Prince Edward Island Potatoes are marketed and trademarked as being grown in the unique growing conditions and climate of Prince Edward Island. Prince Edward Island's growing conditions are characterized by warm summers, relatively cold winters, significant natural precipitation, and a unique red soil high in iron
Blackleg (potatoes) it is critically important to keep the potatoes at a low temperature with adequate aeration and humidity control in order to minimize development of the pathogen in infested stocks. New research on "P. atrosepticum" virulence pathways has elucidated the use of quorum sensing molecules to exhibit pathogenicity. These pathways include the control of the production of plant cell wall degrading enzymes in addition to other virulence factors. Research indicating the role of other soil microbes in degrading "P. atrosepticum" quorum sensing communication molecules provides the possibility for safe and effective control of the disease. Plant defense mechanism studies on "P.
