Summary

  • Worldwide distribution. On sugarcane, maize and sorghum, crop relatives and wild species. Important fungal disease.
  • Infections through nodes and wounds. Large red external patches, and internal rots with white spots at right angles to stem. Leaves yellow, dry and die.
  • Spread in setts, and by water-splashed spores.
