How to Get Rid of Slaters on Edamame Plant

Edamame is a popular and healthy snack that is enjoyed around the world. However, if you are growing edamame in your garden, you may have noticed an infestation of slaters (also known as pillbugs or woodlice) on your plants. Slaters are small, grayish-brown insects that can damage your edamame plants by feeding on the leaves and stems. Fortunately, there are several ways to get rid of slaters and protect your edamame crop.

Identify the Problem

Before you can effectively eliminate slaters from your edamame plant, it’s important to identify the problem. Look for small holes in the leaves and stems of your plants or for irregular patches of missing tissue. Check the soil around the base of the plant for slaters or their eggs. Slaters thrive in moist environments, so if your soil is too wet or if you are over-watering your plants, this could be contributing to the problem.

Natural Remedies

There are several natural remedies that can help control slater infestations:

1. Diatomaceous Earth

Diatomaceous earth is a fine powder made from the fossilized remains of diatoms. It is a natural insecticide that is safe for humans and pets but deadly to slaters. Sprinkle a thin layer of diatomaceous earth around the base of your edamame plants to create a barrier that slaters cannot cross.

2. Eggshells

Eggshells are another effective natural remedy for slaters. Crushed eggshells create sharp edges that can cut and deter slaters from climbing onto your plants. Scatter crushed eggshells around the base of your edamame plants to repel slaters.

3. Coffee Grounds

Coffee grounds have a high acidity level that slaters cannot tolerate. Sprinkle coffee grounds around the base of your edamame plants to repel slaters and fertilize your soil at the same time.

Chemical Remedies

If natural remedies do not work, you may need to resort to chemical remedies. However, it’s important to use chemicals safely and responsibly:

1. Insecticides

Insecticides are chemical compounds that kill insects. Look for an insecticide that is labeled safe for use on vegetables and follow the instructions carefully. Apply the insecticide to the base of your edamame plants, being careful not to get any on the leaves or pods.

2. Baits

Baits are another type of chemical remedy that can be effective against slaters. Baits contain a poison that is attractive to slaters but not harmful to humans or pets. Place baits around the base of your edamame plants and replace them as needed.

Prevention

Prevention is often the best way to avoid slater infestations in the first place:

1. Watering

Avoid over-watering your plants and make sure the soil around the base of your edamame plants is well-drained. Slaters thrive in moist environments, so keeping your soil dry can help prevent infestations.

2. Mulch

Mulch can help regulate soil moisture and temperature and create a barrier against slaters. Use a layer of organic mulch around the base of your edamame plants to deter slaters from climbing onto your plants.

3. Clean Up

Slaters are attracted to decaying plant matter, so it’s important to keep your garden clean and tidy. Remove any dead leaves or debris from around your edamame plants to reduce the likelihood of infestations.
