How to Get Rid of Scales on Exacum Plant

Exacum is a tropical plant that is known for its beautiful purple flowers. It is a popular choice among gardeners who love to add color to their gardens. However, like any other plant, Exacum can fall victim to pests and diseases. One of the most common problems that Exacum plants face is the infestation of scales. Scales are tiny insects that attach themselves to the leaves and stems of the plant and cause damage. In this article, we will discuss how to get rid of scales on Exacum plants.

What are Scales?

Scales are small insects that attach themselves to the leaves and stems of plants and feed on their sap. They are called scales because they have a hard, protective covering that resembles a scale. Scales can be of different types, but the most common ones that attack Exacum plants are the soft brown scale and the cottony cushion scale.

Soft brown scales are flat and oval-shaped insects that have a brownish-yellow color. They are very small, ranging from 1-3mm in size. Cottony cushion scales, on the other hand, are round and fluffy insects that have a white or pinkish color. They are slightly bigger than soft brown scales and can grow up to 5mm in size.

How to Identify if Your Exacum Plant has Scales?

Scales can be difficult to spot because they attach themselves very firmly to the leaves and stems of the plant. However, there are some signs that you can look out for to identify if your Exacum plant has scales:

• The leaves of the plant may have a sticky substance on them, which is the honeydew secreted by the scales.
• The leaves may turn yellow or brown and fall off.
• You may see small bumps or protrusions on the leaves or stems of the plant, which are the scales.
• If you look closely, you may be able to see the scales moving on the plant.

How to Get Rid of Scales on Exacum Plants?

Getting rid of scales on Exacum plants is not an easy task, but it is not impossible either. Here are some methods that you can use to get rid of scales:

1. Manual Removal

The first and most basic method of getting rid of scales is manual removal. You can use a soft-bristled brush or a cotton swab dipped in alcohol to remove the scales from the plant. Make sure to be gentle while doing so, as Exacum plants are delicate and can get damaged easily.

2. Insecticidal Soap

Insecticidal soap is a natural and safe way to get rid of scales on Exacum plants. You can buy insecticidal soap from any garden store or make your own at home by mixing liquid soap with water. Spray the solution on the affected area of the plant, making sure to cover all the scales. Repeat the process every 7-10 days until all the scales are gone.

3. Neem Oil

Neem oil is another natural and safe way to get rid of scales on Exacum plants. Neem oil contains azadirachtin, which is toxic to insects but safe for plants and humans. Mix neem oil with water and spray it on the affected area of the plant. Repeat the process every 7-10 days until all the scales are gone.

4. Systemic Insecticides

If manual removal, insecticidal soap, or neem oil do not work, you can use systemic insecticides to get rid of scales on Exacum plants. Systemic insecticides are absorbed by the plant and spread throughout its system, killing all the insects that feed on it. However, systemic insecticides are toxic and should be used as a last resort.
