• Leaf Spots: Caused by fungus, this disease causes brown spots on the leaves.
• Crown Rot: Caused by waterlogging and poor drainage, this disease affects the crown of the plant.
• Powdery Mildew: Caused by a fungus, this disease creates a white powdery coating on the leaves.
• Bacterial Wilt: Caused by bacteria, this disease results in wilted leaves and stems.
