The infection starts at the collar region of the pseudostem and progresses upwards as well as downwards.
The collar region of the affected pseudostem becomes water soaked and the rotting spreads to the rhizome resulting in soft rot.
At a later stage root infection is also noticed.
Foliar symptoms appear as light yellowing of the tips of lower leaves which gradually spreads to the leaf blades.
In early stages of the disease, the middle portion of the leaves remain green while the margins become yellow.
Later, the yellowing spreads to all leaves of the plant from the lower region upwards and is followed by drooping, withering and drying of pseudostems.
Management
Select healthy seed rhizomes from disease free areas.
Ensure proper drainage of the field.
When the disease incidence is noted in the field, dig out the affected plants and drench the beds with Bordeaux mixture (1%).
