Following uprooting of roots and stumps of 50 white spruce trees from different sites in the Grand'Mère plantations, strangulated primary roots were found to be the main points of entry of root-rot organisms. These fungi and other (hyphomycete) fungi were observed to influence each other in the development of root rot. Twisting in planting seems to have been the main factor leading to root mortality.
