| Erwinia rot: Erwinia carotovora sub sp. carovora |
Symptom:
- This disease is more pronounced on young suckers leading to rotting and emitting of foul odour
- Roting of crown region is a characteristic symptom followed by epinasty of leaves, which dry out suddenly
- If affected plants are pulled out it comes out from the crown region leaving the corm with their roots in the soil
- Splitting of pseudostem is common in late stage of infection in cultivars Robusta, Grand Naine and Thella Chakkerakeli
- When affected plants are cut open at collar region yellowish to reddish ooze is seen
- This soft rotting may spread radially towards growing point through the cortical tissues. The rotten corm emits foul smell
- The disease can be spread by infected plant debris, plant wounds and injuries. Hot and damp weather with plenty of rainfall trigger the disease to occur. Water is required for the bacteria to invade into the plant
