Sirococcus shoot blight on Picea spinulosa in Bhutan

During a recent survey of forest tree diseases in Western and Central Bhutan, Sirococcus shoot blight and an associated Sirococcus sp. were found on saplings and mature trees of Eastern Himalayan spruce (Picea spinulosa). Based on morphological characteristics and DNA sequence comparisons of the ITS region of the rDNA operon, representative isolates from Bhutan were unequivocally identified as Sirococcus conigenus. The DNA sequence data also showed that these isolates belong to the P group of S. conigenus. To our best knowledge, this is the first report of Sirococcus shoot blight from the Himalayas or any other part of Asia. Sirococcus conigenus does not appear to cause dramatic damage at the moment, but this fungus has the potential to cause severe disease problems on P. spinulosa in Bhutan.We thank the Conifer Research and Training Partnership (CORET, http://woek.boku.ac.at/coret/), funded by the Austrian Development Co-operation (Austrian Ministry of Foreign Affairs) and the Royal Government of Bhutan for the opportunity and partial funding to undertake this study
