How to Get Rid of Borers on Colocasia Plant

Updated: March 11, 2023

Colocasia, also known as elephant ear, is a tropical plant with large, heart-shaped leaves that can add a dramatic touch to any garden. However, like any other plant, it is susceptible to pests and diseases. One of the most common problems that gardeners face with colocasia is borers. Borers are insects that tunnel into the plant’s stem, causing damage and weakening the plant. If left untreated, borers can kill the entire plant. In this article, we will discuss how to get rid of borers on colocasia plants.

Identify the Problem

Before you can get rid of borers on your colocasia plant, you need to identify the problem. Borers are small, white or cream-colored insects that tunnel into the stems of the plant. The damage they cause can result in wilting or yellowing of leaves and stunted growth. You may also notice small holes in the stem and sawdust-like frass around the base of the plant.

Prevention

Prevention is always better than cure when it comes to pests and diseases. Here are some steps you can take to prevent borers from attacking your colocasia plant:

  • Plant healthy specimens: Make sure you buy healthy colocasia plants from reputable nurseries or garden centers.
  • Avoid over-fertilizing: Over-fertilizing can make your plants more susceptible to pests and diseases.
  • Practice good sanitation: Remove any dead or damaged foliage or stems from your plants regularly.
  • Inspect your plants regularly: Check your plants regularly for any signs of borers or other pests and diseases.

Treatment

If your colocasia plant is already infested with borers, there are several treatment options available:

1. Manual removal

The first step in getting rid of borers is to manually remove them from the plant. You can do this by carefully cutting into the affected stem and removing the borer. Make sure to dispose of the borer in a sealed bag to prevent it from spreading to other plants.

2. Insecticides

There are several insecticides available that can effectively kill borers on colocasia plants. Look for insecticides that contain imidacloprid or carbaryl. Follow the instructions carefully when applying insecticides, and wear protective clothing and gloves.

3. Beneficial insects

Beneficial insects, such as parasitic wasps and nematodes, can also be used to control borers on colocasia plants. These insects prey on borers and can help reduce their population.

FAQ

Can I use neem oil to get rid of borers on my colocasia plant?

Neem oil is an effective natural insecticide that can help control borers on colocasia plants. However, it may not be as effective as chemical insecticides.

How often should I inspect my colocasia plants for borers?

It is recommended that you inspect your plants at least once a week during the growing season.

Will pruning my colocasia plant help get rid of borers?

Pruning can help remove any damaged or diseased parts of the plant, but it may not necessarily get rid of all the borers.

In conclusion, borers can be a serious problem for colocasia plants, but with proper prevention and treatment, you can keep your plants healthy and thriving. By identifying the problem, practicing good sanitation, and using the right treatment methods, you can get rid of borers and enjoy your beautiful colocasia plant for years to come.
