Most Common Edamame Plant Pests:
Identification and Treatment Guide

Edamame is a delicious and nutritious snack that has gained popularity in recent years. However, like any other plant, edamame is vulnerable to pests that can cause damage to the plant and reduce yields. In this article, we will discuss the most common edamame plant pests, how to identify them, and how to treat them.

1. Aphids

Aphids are small, soft-bodied insects that suck sap from the plant. They are usually found on the underside of leaves and can cause stunted growth, yellowing leaves, and distorted plant growth.

Identification

Aphids are usually green or yellow in color, but they can also be black or brown. They are about 1/8 inch long and have long antennae.

Treatment

You can use insecticidal soap or neem oil to treat aphids. These products work by suffocating the insects. You can also introduce natural predators such as ladybugs or lacewings to control aphid populations.

2. Bean Leaf Beetle

Bean leaf beetles are small, oval-shaped insects that feed on the leaves of the edamame plant. They can cause defoliation and reduce yields.

Identification

Bean leaf beetles are usually yellow or tan in color with black spots on their backs. They are about 1/4 inch long and have long antennae.

Treatment

You can use insecticides such as carbaryl or pyrethrin to control bean leaf beetles. You can also cover your plants with row covers to prevent beetles from laying eggs on your plants.

3. Cutworms

Cutworms are caterpillars that feed on the stems of young edamame plants. They can cause wilting and death of the plant.

Identification

Cutworms are usually brown or gray in color and about 1-2 inches long. They are active at night and can be found curled up around the base of the plant during the day.

Treatment

You can use Bacillus thuringiensis (BT) or spinosad to control cutworms. These products are effective against caterpillars and are safe for humans and pets.

4. Japanese Beetle

Japanese beetles are a destructive pest that feed on the leaves, flowers, and fruit of edamame plants. They can cause significant damage and reduce yields.

Identification

Japanese beetles are about 1/2 inch long and have a metallic green head and thorax with copper-colored wings.

Treatment

You can use insecticides such as carbaryl or pyrethrin to control Japanese beetles. You can also handpick them off your plants in the early morning when they are sluggish.

5. Spider Mites

Spider mites are tiny, sap-sucking pests that can cause yellowing leaves and reduced yields.

Identification

Spider mites are about 1/50 inch long and can be red, yellow, or green in color. They can be difficult to see with the naked eye, but you may notice webbing on the plant.

Treatment

You can use insecticidal soap or neem oil to control spider mites. You can also introduce natural predators such as ladybugs or lacewings to control spider mite populations.
