Dumbcane, scientifically known as Dieffenbachia, is an attractive indoor plant with large leaves, and it is a favorite of many plant enthusiasts. However, just like any other plant, dumbcane is susceptible to pest infestations. One of the most common pests that attack dumbcane plants is borers. Borers are insects that feed on the inside of the stem, causing damage to the plant’s tissues, and they can be challenging to get rid of. In this article, we will explore how you can get rid of borers on dumbcane plants.

Identifying Borers on Dumbcane Plant

Before we discuss how to get rid of borers on dumbcane plants, it’s essential to know how to identify them. Borers are small insects with long and narrow bodies that can be white, yellow, or brown in color. They bore into the stems of the plant and feed on the inside tissues, causing damage to the plant. Signs of borer infestation include wilting or yellowing leaves, stunted growth, and holes in the stem.

How to Get Rid of Borers on Dumbcane Plant

Getting rid of borers on dumbcane plants requires a combination of physical and chemical methods. Here’s what you need to do:

1. Prune Infested Areas

The first step in getting rid of borers on dumbcane plants is to prune infested areas. Locate the areas where the borers are present and cut them off using a sharp and sterilized pair of scissors. Make sure you dispose of the infested parts far away from your plant to avoid re-infestation.

2. Apply Insecticide

After pruning, apply an insecticide that contains carbaryl or cyfluthrin to eliminate any borers that might be hiding in the plant. Follow the manufacturer’s instructions carefully when applying insecticide to avoid damaging your plant.

3. Use Beneficial Nematodes

Beneficial nematodes are microscopic worms that feed on borers and other harmful insects. You can purchase nematodes online or at a garden center and apply them to your plant’s soil. The nematodes will penetrate the soil and kill any borers that come into contact with them.

4. Maintain Proper Plant Care

Maintaining proper plant care is essential in preventing borer infestations in your dumbcane plants. Ensure your plant is getting enough sunlight, water, and nutrients to keep it healthy and less susceptible to pests. Also, make sure you’re not over-fertilizing your plant, as this can attract pests.
