Abstract
Fusarium commune can cause damping-off and root rot of conifer seedlings in forest nurseries. The pathogen is only reported in Oregon, Idaho, and Washington within United States. Fusarium isolates were collected from midwestern and western United States to determine occurrence of this pathogen. DNA sequences of mitochondrial small subunit gene were used to identify F. commune. In addition to the aforementioned states, F. commune was found from nurseries in Nevada, Montana, Nebraska, and Michigan, USA.
