Botryodiplodia gallae was confirmed by wound inoculation as the cause of a canker disease that contributes to poor sprout survival after clear-cutting oak stands (Quercus alba, Q. velutina, Q. ellipsoidalis, and occasionally, Q. rubra) in the Huron-Manistee National Forest in Michigan. There was no significant difference in the number of cankers per stem between white and red oak groups.
