Common Gold Dust Plant Diseases:
How to Identify and Treat

The Gold Dust plant (Aucuba japonica) is a popular shrub with glossy green leaves splashed with yellow spots. It is easy to care for and adds a splash of color to any landscape. However, like any other plant, the Gold Dust plant is susceptible to diseases. In this article, we will discuss some of the most common Gold Dust plant diseases, how to identify them, and how to treat them.

Leaf Spot

Leaf spot is a fungal disease that affects many ornamental plants, including the Gold Dust plant. The fungus usually attacks the leaves, causing circular or irregular-shaped spots that are brown or black in color. As the disease progresses, the spots may merge and cover large portions of the leaf.

Identification

To identify leaf spot disease in your Gold Dust plant, look for brown or black circular or irregular-shaped spots on the leaves. The spots may have a yellow halo around them.

Treatment

To treat leaf spot disease, remove all infected leaves and dispose of them in the trash. Avoid watering your plant from above as this can spread the fungus. Instead, water at the base of the plant. You can also apply a fungicide labeled for leaf spot disease.

Anthracnose

Anthracnose is another fungal disease that affects many ornamental plants, including the Gold Dust plant. The fungus attacks the leaves, causing them to wilt and turn brown or black. If left untreated, anthracnose can cause severe damage to your Gold Dust plant.

Identification

To identify anthracnose disease in your Gold Dust plant, look for wilting leaves that turn brown or black. The veins on the leaves may also turn black.

Treatment

To treat anthracnose disease, remove all infected leaves and dispose of them in the trash. Avoid watering your plant from above as this can spread the fungus. Instead, water at the base of the plant. You can also apply a fungicide labeled for anthracnose disease.

Root Rot

Root rot is a fungal disease that affects the roots of plants. It is caused by overwatering or poorly drained soil. The fungus attacks the roots, causing them to rot and eventually die. This can cause severe damage to your Gold Dust plant and may even kill it.

Identification

To identify root rot disease in your Gold Dust plant, look for yellowing leaves that are wilting or drooping. The plant may also be stunted and slow-growing. If you gently tug on the plant, it may come out of the ground easily.

Treatment

To treat root rot disease, remove the plant from the soil and gently wash off the roots. Cut off any brown or black roots with a clean pair of scissors. Repot the plant in fresh soil with good drainage. Water sparingly until the plant has recovered.
