ABSTRACT = {In Bazhong City, Sichuan Province, China, top dieback symptoms were found on many pine trees (<i>Pinus thunbergii</i> Parl). The tips of old needles first turned grayish-green and then developed into brown bands in the field. Phylogenetic analysis of concatenated ITS and EF1-α indicated the pathogen of this dieback disease as <i>Diplodia neojuniperi</i>. Additionally, effects of temperature, pH and medium on the mycelial growth were also characterized. The most favorable temperature and pH level for mycelial growth are 25°C and 8, respectively. The optimal medium for mycelial growth is PDA medium. To our knowledge, this is the first report of <i>D. neojuniperi</i> causes <i>Diplodia</i> top dieback on <i>Pinus thunbergii</i>. Our results provide fundamental information for monitoring and preventing such disease in the future.},
