This study completes Koch's postulates for P. hibernalis on rhododendron. P. hibernalis has previously been described as causing brown rot of citrus. This report expands the pathogen's known natural host range. P. hibernalis does not appear to be widespread in the California and Oregon nursery industries, but was recovered in both states for three consecutive years. Accepted for publication 8 July 2005.
