What is Crepe myrtle disease?

Crepe myrtle disease, primarily associated with the fungal pathogen Erysiphe pulchra, causes powdery mildew on crepe myrtle trees, leading to white, powdery spots on leaves. This disease can weaken the plant, reduce its aesthetic appeal, and result in premature leaf drop. Environmental conditions such as high humidity and poor air circulation can exacerbate the disease. Effective management includes proper pruning, ensuring adequate airflow, and applying fungicides if necessary.
