Donkey ear plants, also known as Alocasia, are a popular choice for indoor and outdoor gardening. They have large, exotic leaves that can add a touch of tropical elegance to any space. However, like any other plant, donkey ear plants are susceptible to pests and diseases. One of the most common problems faced by donkey ear plant owners is borer infestation. Borers are insects that bore into the stems of the plant and cause significant damage. If left untreated, borers can kill the plant. In this article, we will discuss how to identify and get rid of borers on donkey ear plants.

Identifying Borer Infestation

Borers are small insects that lay their eggs on the stems of the plant. When the eggs hatch, the larvae bore into the stem and start feeding on the plant’s tissue. As they feed, they create tunnels inside the stem, which weakens the plant and makes it susceptible to disease.

The first sign of borer infestation is wilting leaves. The leaves may turn yellow or brown and fall off the plant. You may also notice sawdust-like material around the base of the stem or small holes in the stems.

Getting Rid of Borers

If you suspect that your donkey ear plant has a borer infestation, it’s essential to act quickly. Here are some steps you can take to get rid of borers:

1. Prune Infested Areas

Using a sharp pair of scissors or pruning shears, remove any infested parts of the plant. Cut at least an inch below the damaged area to ensure that all the larvae are removed. Dispose of the affected parts in a sealed bag or burn them to prevent further infestation.

2. Apply Insecticides

Insecticides can be an effective way to get rid of borers. Look for a product that contains imidacloprid or cyfluthrin, which are known to be effective against borers. Follow the manufacturer’s instructions carefully when applying the insecticide, and make sure to cover all parts of the plant.

3. Use Beneficial Insects

Beneficial insects, such as parasitic wasps, can help control borer infestation. These insects lay their eggs on the larvae of borers, which kills them before they can cause significant damage to the plant. You can purchase beneficial insects online or from a local garden center.

4. Improve Plant Health

Healthy plants are less susceptible to pests and diseases. Make sure your donkey ear plant is getting enough water, sunlight, and nutrients. Avoid over-fertilizing the plant, as this can attract pests like borers.
