Edamame is a popular Japanese snack made from soybeans. These beans are not only delicious but also very nutritious. However, edamame plants are susceptible to worm infestations, which can damage the crop and affect its quality. If you’re an edamame farmer or gardener, you need to know how to get rid of worms in your plants. This article will provide you with some effective methods.

Identify the Worms

Before you start treating your edamame plants for worm infestations, it’s essential to identify the worms that are causing the damage. There are two types of worms that commonly infest edamame plants: the bean leaf beetle and the soybean pod borer.

The bean leaf beetle is a small, yellowish-green beetle that feeds on the leaves of edamame plants. The larvae of this beetle are small, white, and worm-like. They will eat the roots of the plant and cause significant damage if left unchecked.

The soybean pod borer is a small caterpillar that feeds on the pods of edamame plants. These caterpillars are light green and have a black head. They burrow into the pods and feed on the developing seeds, causing them to shrivel and die.

Use Organic Pesticides

One way to get rid of worms in your edamame plants is by using organic pesticides. These pesticides are made from natural ingredients and are safe for both humans and the environment.

Some organic pesticides that are effective against bean leaf beetles include neem oil, insecticidal soap, and pyrethrin. To use these pesticides, mix them with water according to the instructions on the label and spray them on your edamame plants.

For soybean pod borers, you can use Bacillus thuringiensis (Bt). Bt is a natural bacteria that specifically targets caterpillars. When the caterpillars eat the Bt, it will disrupt their digestive system, causing them to stop feeding and eventually die.

Practice Crop Rotation

Another way to prevent worm infestations in your edamame plants is by practicing crop rotation. Worms can lay eggs in the soil, and if you plant edamame in the same spot every year, the worms will continue to infest your plants.

To break the cycle, plant a different crop in the same spot every other year. This will give the soil time to recover and reduce the number of worms in your garden.


If you only have a few edamame plants, you can handpick the worms off your plants. This method is time-consuming but effective.

Check your plants every day for signs of worm infestations. Look for chewed leaves or pods with holes. If you find any worms, pick them off and drop them into a bucket of soapy water to kill them.


Are there any other pests that can infest edamame plants?

Yes, edamame plants can also be infested with aphids, spider mites, and whiteflies. These pests can be controlled with organic pesticides or by using beneficial insects like ladybugs and lacewings.

Can I use chemical pesticides on my edamame plants?

It’s not recommended to use chemical pesticides on edamame plants because they can be harmful to humans and the environment. Organic pesticides are a safer option.

When is the best time to plant edamame?

Edamame should be planted in late spring or early summer when the soil temperature reaches at least 60°F (15°C).

In conclusion, worm infestations can be a significant problem for edamame farmers and gardeners. However, with the right methods, you can get rid of worms and protect your crop. Organic pesticides, crop rotation, handpicking, and other preventive measures can help keep your edamame plants healthy and worm-free.
