Symptoms

  • Leaves of infected plants turn yellow to a light tan to brown before dying.

  • Younger leaves often turn red.

  • Basal stem and leaf sheath rot, affected plants are easy to pull out.

  • Infected areas are seen as irregular shaped patches.

  • Affected patches are a reddish brown colour turning yellow then tan to brown.

  • A black stain may occur at the base of infected plants, this is an acervulus, a black fungal fruiting body.

Conditions Favouring Disease

  • Disease development is favoured by warm humid conditions.

  • Anthracnose favours temperatures over 25°C.

  • It is necessary for a film of moisture to be present on either the roots or foliage for infection to occur.

  • Hot summers in cool temperature areas are when the disease is most noticeable.

  • Soil compaction and low amounts of nitrogen also contribute to disease occurrence.
