Red rot disease is caused by the fungus Glomerella tucumanensis. Pathogen present on leaf sheaths and blades, solitary or aggregated, often forming short lines between vascular bundles .There has been considerable difference in opinion as to the nature of the fungus that causes this disease. Some insisted that this fungus is more strictly saprophytic than parasitic, and that it cannot attack healthy canes. Others said that it cannot attack mature canes except through wounds, but that it can attack young plants. However, the young canes are usually protected by the leaf sheaths. In some places the fungus has been reported to grow on the dead canes only and the disease is not known.
