How to Get Rid of Lerps on Horsetail Reed Plant

If you have a horsetail reed plant in your garden, you may have encountered a common problem known as lerps. Lerps are small, white, waxy structures that appear on the leaves of the plant, causing damage and hindering its growth. In this article, we will discuss what lerps are, how they affect horsetail reed plants, and most importantly, how to get rid of them.

Understanding Lerps

Lerps are actually protective coverings created by tiny insects known as psyllids. These insects lay their eggs on the leaves of horsetail reed plants and secrete a sticky substance which hardens into a protective shell. The shell, or lerp, serves as a shield for the nymphs as they feed on the plant’s sap.

The presence of lerps not only affects the aesthetic appeal of the horsetail reed plant but also impedes its ability to carry out photosynthesis effectively. As a result, the plant’s growth can be stunted, and it may become more susceptible to diseases and other pests.

Natural Methods to Remove Lerps

When it comes to dealing with lerps on horsetail reed plants, it is best to start with natural methods before resorting to chemical treatments. Here are some effective ways to remove lerps naturally:

1. Prune Affected Leaves

Inspect your horsetail reed plant and identify the leaves infested with lerps. Carefully prune these affected leaves using sharp pruning shears or scissors. Be sure to dispose of the pruned leaves properly to prevent further infestation.

2. Blast with Water

Using a strong jet of water from a hose or pressure washer, carefully spray the affected parts of the horsetail reed plant. The force of the water can dislodge the lerps and wash them away. Repeat this process regularly until the infestation is under control.

3. Apply Neem Oil

Neem oil is a natural insecticide that can effectively deter and kill lerps without harming the plant or beneficial insects. Mix one part neem oil with ten parts water and spray it onto the affected areas of the horsetail reed plant. Repeat this treatment every two weeks until the infestation subsides.

4. Introduce Beneficial Insects

Certain predatory insects, such as ladybugs and lacewings, feed on psyllids and can help control their population. You can attract these beneficial insects to your garden by planting flowers like daisies, marigolds, and alyssum. Additionally, you can purchase beneficial insects from garden supply stores and release them near the affected horsetail reed plant.

Chemical Treatments for Severe Infestations

If natural methods do not provide satisfactory results or if the infestation is severe, you may need to resort to chemical treatments. However, it is important to exercise caution when using pesticides to avoid harming beneficial insects and pollinators. Here are a few options for chemical treatments:

1. Insecticidal Soap

Insecticidal soap is a safe and effective option for controlling lerps on horsetail reed plants. It works by suffocating the insects, causing them to die off. Dilute the insecticidal soap according to the manufacturer’s instructions and apply it directly to the affected areas of the plant.

2. Systemic Insecticides

Systemic insecticides are absorbed by the plant and distributed throughout its tissues, making them an effective option for controlling lerps that are difficult to reach with sprays. However, caution must be exercised when using systemic insecticides, as they can also harm beneficial insects and pollinators. Follow the manufacturer’s instructions carefully and use them sparingly.

Preventing Future Infestations

Once you have successfully eradicated the lerps from your horsetail reed plant, it is important to take preventive measures to avoid future infestations. Here are some tips to keep your horsetail reed plant healthy and lerp-free:

• Regularly inspect your plant for early signs of infestation, such as the appearance of white, waxy structures or sticky residue on the leaves.
• Keep your horsetail reed plant well-watered and properly fertilized to ensure its overall health and resilience against pests.
• Maintain good garden hygiene by removing fallen leaves and debris regularly, as these can attract insects.
• Encourage biodiversity in your garden by planting a variety of native plants. This will attract beneficial insects that can help control psyllids and other pests.

In conclusion, lerps can be a nuisance for horsetail reed plants, affecting their growth and overall health. By employing natural methods like pruning, water blasting, and using neem oil, you can effectively remove lerps from your plant. In severe cases, chemical treatments such as insecticidal soap or systemic insecticides may be necessary. Remember to practice preventive measures to avoid future infestations and keep your horsetail reed plant thriving.
