Common Dorado Plant Diseases:
How to Identify and Treat

Updated: May 20, 2022

Dorado plants are popular with gardeners because of their striking foliage and colorful flowers. However, like any other plant, dorado plants are susceptible to diseases. Some diseases can be deadly if not identified and treated early enough. In this article, we will discuss the most common dorado plant diseases, how to identify them, and the best treatment options.

Powdery Mildew

Powdery mildew is a fungal disease that affects many plants, including dorado plants. It appears as a white powdery substance on the leaves, stems, and flowers of the plant. The fungal spores spread quickly in warm and humid conditions, which is why powdery mildew is common in late summer and early fall.

Identification

Powdery mildew first appears as small white spots on the leaves of the plant. As the disease progresses, the spots merge into larger patches, forming a powdery coating on the leaves. The leaves may also turn yellow or brown and eventually wilt.

Treatment

The best way to control powdery mildew is to prevent it from occurring in the first place. You can do this by ensuring proper air circulation around your dorado plants by spacing them out properly. If your dorado plant is already infected with powdery mildew, you can treat it by spraying it with a fungicide such as neem oil or copper sulfate.

Leaf Spot

Leaf spot is another fungal disease that affects dorado plants. It appears as circular brown spots with yellow margins on the leaves of the plant. The disease can cause defoliation if not treated early enough.

Identification

Leaf spot first appears as small brown spots on the leaves of the plant. As the disease progresses, the spots enlarge and merge to form irregularly shaped lesions with yellow margins. The leaves may also become distorted or drop prematurely.

Treatment

To control leaf spot, you should remove and dispose of any infected leaves or plant debris. You can also spray your dorado plants with a fungicide such as copper sulfate or chlorothalonil.

Root Rot

Root rot is a fungal disease that affects the roots of dorado plants. It occurs when the soil around the plant becomes waterlogged, creating the ideal conditions for the fungus to thrive. The disease can kill your dorado plant if not treated early enough.

Identification

Root rot first appears as yellowing leaves, wilting, and stunted growth. As the disease progresses, the leaves may drop off, and the stem may become soft and mushy.

Treatment

To control root rot, you should ensure proper drainage around your dorado plants by improving the soil structure or planting your dorado plants in well-draining soil. If your dorado plant is already infected with root rot, you can apply a fungicide such as copper sulfate or thiophanate-methyl.
