Overview

Observation of brown leaf spot disease in Dendrobium denneanum highlights Phyllosticta capitalensis pathogenicity in Zhejiang.

Key Points

  • Symptoms of brown leaf spot disease emerged in Dendrobium denneanum, with around 30% disease incidence observed.
  • Fungal isolates resembling Phyllosticta capitalensis were obtained, sharing 99% similarity based on genetic sequencing.
  • Pathogenicity was confirmed through inoculation, resulting in symptoms identical to those seen in the wild.
  • This finding emphasizes the need for strategies to control brown leaf spot disease in medicinal plants.
