摘要：Blighted red pine shoots, either having symptoms only on the most recent year's growth or having symptoms present both on most recent and previous year's growth, were examined for pycnidia of Sirococcus conigenus, Diplodia pinea, or both. On shoots having symptoms only on the most recent year's growth, S. conigenus was detected more frequently than D. pinea. On shoots having symptoms on both the most recent and the previous year's growth, however, D. pinea was detected more frequently than S. conigenus on the most recent year's growth. In addition, on those shoots having symptoms on both the most recent and the previous year's growth, D. pinea was detected almost eight times more frequently on the previous year's growth than the most recent year's growth. Whether only one pathogen was detected or the two pathogens were detected co-occurring on a single year's growth also varied with shoot condition and shoot year of growth, but the two fungi co-occurred on shoots of each condition
