Overview

Field observation reveals damping-off and rhizome rot caused by Globisporangium spinosum on ginger, indicating a new threat to ginger crops in China.

Key Points

  • Inoculated ginger plants developed symptoms of yellowing and damping-off, confirming pathogenicity of Globisporangium spinosum.
  • Rhizomes exhibited rot and dense white mycelia within seven days post-inoculation, showing severe disease impact.
  • Morphological and molecular analyses confirmed the identity of the pathogen as Globisporangium spinosum using ITS and COI sequences.
  • This finding highlights the need for effective control measures against Globisporangium spinosum affecting ginger in agricultural fields.
