Godronia cassandrae f. sp. vaccinii (imperfect or anamorph stage - Fusicoccum putrefaciens) is a fungal pathogen that causes stem canker on many Vaccinium species, including highbush blueberry, cranberry, and many woody perennials. Although Godronia canker on blueberries is known to occur in the northern United States and southern Canada, it was not being considered a major threat to blueberry production in the lower mainland of BC, causing substantial yield losses and crop damage. Since 2008, the incidence of the disease has reached epidemic proportions in a number of fields.
