Abstract

Fusarium commune can cause damping-off and root rot of conifer seedlings in forest nurseries, and this pathogen has been previously reported from Oregon, Idaho, and Washington, USA. We collected Fusarium isolates from additional nurseries in the midwestern and western USA to more fully determine occurrence of this pathogen. We used DNA sequences of the mitochondrial small subunit gene to identify F. commune. In addition to confirming the occurrence of F. commune in Oregon, Idaho, and Washington, USA, we also discovered that F. commune is even more widespread with this first report of F. commune occurring in Nevada, Montana, Nebraska, and Michigan, USA.
