Introduction

Trumpet plants, also known as angel’s trumpets or brugmansias, are beautiful flowering plants that can add elegance and fragrance to any garden or patio. However, these plants are sometimes plagued by slaters, also known as sowbugs or woodlice. Slaters are small crustaceans that feed on decaying organic matter and can damage the leaves and flowers of the trumpet plant. If you’re dealing with a slater infestation on your trumpet plant, here are some effective methods to get rid of them.

Identification of Slaters

Before taking any action to control slaters on your trumpet plant, it’s essential to correctly identify them. Slaters are small, grayish-brown creatures with segmented bodies and numerous legs. They have a flattened appearance and can roll into a ball when threatened. Slaters are typically found in dark, damp environments and feed on decaying matter such as dead leaves and wood.

Prevention is Key

The best way to deal with slaters on your trumpet plant is to prevent their infestation in the first place. Here are some preventive measures you can take:

  1. Remove decaying organic matter: Slaters thrive in areas with decomposing organic material. Regularly remove fallen leaves, dead flowers, and any other decaying plant matter from around your trumpet plant.

  2. Improve drainage: Ensure that the soil around your trumpet plant has proper drainage to prevent excessive moisture buildup, as slaters prefer damp environments.

  3. Reduce watering: Overwatering can create a conducive environment for slaters. Water your trumpet plant only when necessary, allowing the top inch of soil to dry out between waterings.

  4. Create barriers: Place a layer of coarse gravel or crushed eggshells around the base of your trumpet plant to create a physical barrier that slaters find difficult to navigate.

Organic Control Methods

If your trumpet plant is already infested with slaters, here are some organic control methods you can try:

  1. Handpicking: One of the simplest ways to remove slaters from your trumpet plant is by handpicking them. This method works best when dealing with a small infestation. Simply wear gloves and pick the slaters off the leaves, flowers, and stems. You can then dispose of them by placing them in a container filled with soapy water.

  2. Traps: Another effective method is to use traps to attract and capture slaters. You can create a simple trap by placing a moist piece of newspaper or cardboard near the base of your trumpet plant. Slaters are attracted to the moisture and will gather underneath. Check the trap regularly and remove the captured slaters.

  3. Natural predators: Introducing natural predators can help control the slater population on your trumpet plant. Predators such as ground beetles, centipedes, and spiders feed on slaters and can help keep their numbers in check. Encourage these beneficial insects in your garden by providing suitable habitats such as rocks, logs, or mulch.

  4. Diatomaceous earth: Diatomaceous earth is a natural powder made from fossilized remains of diatoms. It is an effective organic control method for slaters as it dehydrates and kills them upon contact. Sprinkle a thin layer of diatomaceous earth around the base of your trumpet plant to create a barrier that slaters cannot cross.

Chemical Control Methods

If organic control methods do not yield satisfactory results, you may consider using chemical control methods as a last resort. However, it’s important to note that these methods should be used with caution and according to the manufacturer’s instructions. Here are some chemical options for controlling slaters on your trumpet plant:

  1. Insecticidal soap: Insecticidal soaps are formulated to kill soft-bodied insects like slaters. They work by suffocating the pests upon contact. Apply the insecticidal soap according to the instructions on the label, ensuring that you cover all affected areas of your trumpet plant.

  2. Pyrethrin-based insecticides: Pyrethrin-based insecticides are derived from chrysanthemum flowers and are effective against slaters. These insecticides target the nervous system of the pests and cause paralysis and death. Follow the instructions on the product label for application rates and precautions.

Conclusion

Dealing with slaters on your trumpet plant can be frustrating, but with the right methods, you can effectively control their population and protect your plant. Remember to identify the slaters correctly and take preventive measures to avoid infestations in the future. Organic control methods such as handpicking, traps, natural predators, and diatomaceous earth are safe and environmentally friendly options. If necessary, chemical control methods like insecticidal soap or pyrethrin-based insecticides can also be used. By implementing these strategies, you can enjoy a healthy and beautiful trumpet plant free from slater damage.
