| 摘要 | [Objectives]This study was conducted to clarify the species composition of pathogens causing leaf spot disease in yellow peach in Loudi area of Hunan Province and to screen effective control agents. [Methods] Twenty leaf spot samples were collected from yellow peach planting bases in Lengshuijiang and Shuangjiang, Loudi City. Two isolates were obtained through tissue isolation and purification. Identification was performed based on morphological characteristics combined with rDNA-ITS and Bt-2a gene sequence analysis and pathogenicity assay. [Results] The pathogen causing yellow peach leaf spot in this area was Botryosphaeria dothidea. [Conclusions] This study provides a reference basis for the prevention and control of yellow peach leaf spot in Loudi area. |
