Abstract
Procerum root disease (PRD) is caused by the deuteromycete fungus
Leptogruphium procerum (Kendr.) Wingf, formerly
Verticic ladiella procera (Kendr.) and is most commonly isolated from
Pinus sp. L., though the fungus has been isolated from other conifer species including Fraser fir (
Abies fraseri [Pursh] Poir.), Douglas fir (
Pseudotsuga menziesii [Mirb.] France) and Norway spruce (
Picea abies [L.] Karst.) (Alexander et al., 1988). During the last two decades PRD has been responsible for significant economic losses in eastern white pine (
Pinus strobus L.) Christmas tree plantations and trees in the urban landscape throughout the eastern United States (Lackner and Alexander, 1984).
