摘要： A severe disease was observed on sunflower (Helianthus annuus L.) in Ili, Xinjiang China, in 2005. The causal agent was isolated from infected tissues, and its pathogenicity confirmed. Pathogenicity tests showed that the fungus could infect sunflower, which developed the same symptoms under artificial inoculation conditions to those observed in the field. The fungus was identified based on morphological and cultural characteristics as Phoma macdonaldii Boerema. Identifications were confirmed by comparison of the 18S rDNA partial sequence, 28S rDNA partial sequence, and the internal transcribed spacer (ITS) regions 1 and 2, including 5.8S rDNA (ITS1-5.8S-ITS2). This is the first report of black stem of sunflower caused by P. macdonaldii in China.
