Powdery Mildew is a fungal disease characterized by spotting or coating of the leaf surface with a white powdery deposit.
The disease results in disfigured leaves. In severe cases Powdery Mildew can spread to the stems and flowers of the plant.
Powdery Mildew is prevalent in warm humid conditions but it is not as fatal as Botrytis Plant Disease.
1.Remove the badly affected leaves and discard or burn to reduce spread to other parts of the plant.
2.Spray the plant with a systemic fungicide. Ensure all the parts of the plant are completely covered with the fungicidal solution.
3.Alternatively, lightly dust the leaves with a sulphur compound used for this purpose. Ensure the leaves are well covered with the sulphur compound.
4.Improve the air circulation for your houseplant as doing so reduces the occurrence of Powdery Mildew.
