How to Get Rid of Lerps on Viola Plant

Violas are beautiful plants that add color to any garden. However, they are prone to infestations by pests such as the lerp insect. Lerps are small, sap-sucking insects that feed on the leaves and stems of violas. If left unchecked, they can cause significant damage to your plants. In this article, we will discuss how to get rid of lerps on viola plants.

What are Lerps?

Lerps are insects that belong to the family Psyllidae. They are small, measuring about 3mm in length, and are usually found on the undersides of leaves. Lerps feed on plant sap, which they extract using their piercing mouthparts. They secrete a sugary substance called honeydew, which attracts ants and can lead to the growth of sooty mold on the plant.

Identifying Lerp Infestation

Lerps are easy to spot on viola plants. They form a protective shield over themselves using their excreted honeydew and waxy secretions. This shield is called a lerp and appears as a small, white or brown bump on the plant’s leaves or stems.

Other signs of lerp infestation include yellowing or browning of leaves, stunted growth, and wilting.

How to Get Rid of Lerps

  1. Pruning – Remove affected leaves and stems immediately to prevent the spread of infestation. Make sure to dispose of the pruned parts away from the garden.

  2. Water Spray – Use a strong jet of water to dislodge lerps from the plant. Spray the plant thoroughly, paying special attention to the undersides of leaves.

  3. Neem Oil – Neem oil is an effective natural insecticide that can be used to control lerp infestation. Mix neem oil with water and spray it on the plant. Repeat this process every 7-10 days until the infestation is under control.

  4. Insecticidal Soap – Insecticidal soap can be used to kill lerps. Mix the soap with water and spray it on the plant. Make sure to cover all parts of the plant, including the undersides of leaves.

  5. Systemic Insecticide – If other methods fail, a systemic insecticide can be used to control lerp infestation. This type of insecticide is absorbed by the plant and kills lerps when they feed on it.

Preventing Lerp Infestation

Prevention is better than cure when it comes to lerp infestation. Here are some measures you can take to prevent lerps from attacking your viola plants:

  1. Regular Inspection – Inspect your plants regularly for signs of lerp infestation. Early detection can prevent the spread of infestation.

  2. Good Hygiene – Keep your garden clean and free from debris that can harbor pests.

  3. Proper Irrigation – Water your plants properly to prevent water stress, which can make them vulnerable to pests.

  4. Use Organic Fertilizer – Use organic fertilizers that promote plant growth and health, making them less susceptible to pests.
