Welcome to our guide on crepe myrtle diseases pictures. Crepe myrtles are beautiful ornamental trees that are loved for their vibrant blooms and ease of care. However, like all plants, they are susceptible to diseases that can compromise their health and appearance. In this article, we will discuss some of the most common crepe myrtle diseases, how to identify them through pictures, and steps you can take to prevent and treat them.

Common Crepe Myrtle Diseases

Cercospora Leaf Spot

Cercospora leaf spot is a fungal disease that affects the leaves of crepe myrtle trees. It appears as small, circular spots on the leaves that are initially purple and later turn brown. Over time, the spots may grow and merge, causing the leaves to yellow and drop prematurely. In severe cases, the disease can weaken the tree and make it more susceptible to other pests and diseases.

To prevent cercospora leaf spot, avoid overhead watering and keep the area around the tree free of fallen leaves and debris. If your tree is affected, prune off infected leaves and dispose of them properly. Fungicides can also be used to control the disease.

Powdery Mildew

Powdery mildew is a common fungal disease that affects many plants, including crepe myrtles. It appears as a white, powdery coating on the leaves, stems, and flowers of the tree. As the disease progresses, the leaves may curl and distort, and the blooms may become stunted or fail to open.

To prevent powdery mildew, ensure that your tree has adequate air circulation and sunlight. Avoid overhead watering and remove any infected leaves or stems promptly. Fungicides can also be used to control the disease.

Aphids

Aphids are small, soft-bodied insects that suck the sap from crepe myrtle trees. They are often found on the undersides of leaves and can cause the leaves to curl and distort. In severe cases, aphids can weaken the tree and make it more susceptible to other pests and diseases.

To prevent aphids, encourage natural predators such as ladybugs and lacewings in your garden. You can also use insecticidal soap or neem oil to control the population.
