Abstract

Seedlings of lodgepole pine (Pinus contorta var. latifolia), jack pine (P. banksiana), and their hybrid were infected by Dothistroma septosporum under natural conditions in Alberta, Canada, after planting these taxa within a heavily infected stand of lodgepole pine. This experiment has further proven that all three of these taxa are hosts for the pathogen. This information is necessary for assessing the risk of eastward movement of the pathogen from Alberta through populations of P. banksiana in the boreal forest.
