Anthurium (Anthurium spp.)

Anthracnose (Colletotrichum gloeosporioides)

Symptoms

  • Dark, sunken lesions were seen on leaves, stems and flowers.
  • Tiny circular white spots appear on leaf and spadix, later enlarges.
  • Sometimes the entire spadix will turn white as lesions coalesce.
  • The shape of most lesions is, however, angular due to the shape of the spadix tissue.
  • As the disease becomes more severe, masses of orange-coloured spores form on necrotic areas
  • Leaves and spathes are rarely if ever infected.
