How to Get Rid of Aphids on Taro Plant

Updated: July 2, 2023

Aphids are small, sap-sucking insects that can cause significant damage to taro plants if left untreated. These pests feed on the plant’s leaves and stems, causing yellowing, wilting, and stunted growth. If you notice aphids on your taro plants, it’s crucial to take immediate action to prevent further infestation.

Identifying Aphids on Taro Plants

Before you can effectively get rid of aphids, you need to be able to identify them. Aphids are small insects, usually between 1-3mm in size, with pear-shaped bodies. They come in various colors, including green, black, brown, and even pink. Aphids typically gather on the underside of taro leaves or at the growing tips of the plant.

Aphids reproduce rapidly and can establish large colonies within a short period. Therefore, it’s essential to identify and address the issue promptly.

Natural Remedies for Aphid Control

When dealing with aphids on your taro plants, it is recommended to start with natural remedies before resorting to chemical pesticides. Not only are natural solutions safer for the environment, but they also minimize the risk of harmful effects on beneficial insects and other organisms.

1. Homemade Soap Spray

One effective natural remedy for controlling aphids is making a homemade soap spray. To create this spray:

  1. Mix one tablespoon of liquid dish soap with one liter of water.
  2. Pour the solution into a spray bottle.
  3. Spray the affected areas of your taro plant thoroughly, ensuring both sides of the leaves are covered.

The soap spray works by suffocating and dehydrating the aphids. Repeat this process every few days until the aphid population decreases significantly.

2. Neem Oil

Neem oil is another excellent natural remedy for aphid control. It works by disrupting the insect’s hormonal balance and inhibiting their feeding and reproductive abilities. To use neem oil:

  1. Dilute neem oil according to the instructions on the product label.
  2. Spray the diluted neem oil onto the affected areas of your taro plant.
  3. Repeat this process every 7-10 days until the aphids are eliminated.

Ensure you cover all parts of the plant, including the underside of leaves and stems, as aphids tend to hide in these areas.

3. Introduce Beneficial Insects

Another natural way to control aphids is by introducing beneficial insects that prey on them. Ladybugs, lacewings, and parasitic wasps are known to feed on aphids and can help keep their population under control.

You can attract these beneficial insects to your garden by planting flowers such as marigolds, daisies, and yarrow, which act as natural attractants. Alternatively, you can purchase beneficial insects from a reputable supplier and release them near your taro plants.

Cultural Practices to Prevent Aphid Infestations

Apart from using natural remedies, incorporating certain cultural practices can help prevent aphid infestations in the first place. By creating an unfavorable environment for aphids, you can reduce the likelihood of an outbreak.

1. Regularly Monitor Your Plants

Regularly inspecting your taro plants is essential for early detection of aphid infestations. Look out for signs such as curling or yellowing leaves, sticky honeydew residue on leaves, or the presence of ants on your plants.

By catching aphids early on, you can prevent them from spreading and causing significant damage to your taro plants.

2. Remove Infected Plant Parts

If you notice a few leaves or stems heavily infested with aphids, it’s best to remove them immediately. Prune off the affected parts and dispose of them away from your garden to prevent the aphids from spreading to other plants.

3. Encourage Natural Predators

Creating a garden ecosystem that supports beneficial insects is an effective way to control aphids naturally. Provide habitats and food sources for ladybugs, lacewings, and other aphid predators by planting a diverse range of flowers and herbs.

Additionally, avoid using broad-spectrum insecticides that can harm these beneficial insects. Instead, opt for targeted pest control methods to minimize their impact on the ecosystem.

When to Consider Chemical Control

While natural remedies and cultural practices are usually sufficient for managing aphid infestations on taro plants, there may be instances where chemical control becomes necessary. If the infestation is severe and natural methods have failed to provide adequate control, you may need to use insecticides specifically labeled for aphid control.

When using chemical pesticides, always follow the instructions on the label carefully. Apply the pesticide during calm weather conditions to prevent drift and ensure thorough coverage of the affected areas.


Aphids can pose a significant threat to taro plants if left unaddressed. By identifying aphids early on, implementing natural remedies, and practicing cultural prevention methods, you can effectively control and prevent aphid infestations. Remember, it’s crucial to regularly monitor your taro plants and take action promptly to keep these damaging pests at bay.
