To manage leaf spot, remove the affected leaves and dispose of them properly. Spray the plant with a fungicide like copper or sulfur to prevent the spread of the disease.
2. Root Rot: Root rot is a disease caused by fungus or bacteria that affects the roots of the plant. It causes the roots to become mushy and discolored, and the plant can wilt and die. To manage root rot, avoid overwatering the plant and ensure that the soil is well-drained. Remove the affected roots and replant the plant in fresh soil.
3. Powdery Mildew: Powdery mildew is a fungal disease that appears as a white powder on the leaves, stems, and flowers of the plant. It can stunt the growth of the plant and reduce its yield. To manage powdery mildew, remove the affected parts of the plant and dispose of them properly. Spray the plant with neem oil or a fungicide like sulfur or copper to prevent the spread of the disease.
