Most Common Popcorn Plant Pests:
Identification and Treatment Guide

Popcorn is a beloved snack enjoyed by people all over the world. Whether you prefer it salty or sweet, there’s no denying the appeal of this tasty treat. But did you know that popcorn plants can also fall victim to a variety of pests? In this article, we will discuss some of the most common popcorn plant pests, how to identify them, and the best treatment methods to keep your popcorn plants healthy and thriving.

Corn Earworm

One of the most common pests that popcorn plants face is the corn earworm (Helicoverpa zea). These caterpillars feed on the kernels of the plant, causing significant damage. The adult moths lay their eggs on the silks of corn ears, and once they hatch, the caterpillars burrow into the ear and begin to feed.

Identification:

Corn earworm caterpillars are usually pale green or brown in color with dark stripes running along their bodies. They can grow up to 2 inches long and have a distinct head capsule. You may also notice the presence of frass (caterpillar droppings) near the damaged kernels.

Treatment:

To control corn earworm infestations, it is important to practice good sanitation in your garden. Remove any infested ears as soon as you notice them and destroy them to prevent further spread. Applying insecticides specifically formulated for corn earworm control can also be effective. Follow the instructions on the product carefully and apply during the egg-laying period for best results.

Fall Armyworm

Another common pest that affects popcorn plants is the fall armyworm (Spodoptera frugiperda). These pests get their name from their behavior of marching in large numbers when they run out of food. Fall armyworms primarily feed on leaves but can also damage corn ears.

Identification:

Fall armyworm caterpillars are usually light green or brown in color with a distinct inverted “Y” pattern on their heads. They have a smooth body and can grow up to 1.5 inches long. Look for ragged foliage and large numbers of caterpillars to identify an infestation.

Treatment:

To control fall armyworm infestations, it is important to monitor your popcorn plants regularly. Handpicking and destroying any visible caterpillars can help reduce their population. Applying insecticides labeled for fall armyworm control can also be effective. Follow the instructions on the product carefully and ensure thorough coverage of the plants.

Aphids

Aphids are small, soft-bodied insects that can quickly multiply and infest your popcorn plants. These pests suck sap from the plant, causing stunted growth and distortion of leaves.

Identification:

Aphids are typically green, yellow, brown, or black in color and have pear-shaped bodies. They are often found clustered on the undersides of leaves or the tips of new growth. Look for sticky honeydew residue or black sooty mold as signs of their presence.

Treatment:

To control aphid infestations, you can use several methods. One option is to spray a strong stream of water on the affected plants to dislodge the aphids. This can be done regularly until the population is reduced. Additionally, introducing natural predators such as ladybugs or lacewings can help keep aphid populations in check. In severe cases, insecticidal soaps or horticultural oils can be used.

Spider Mites

Spider mites are tiny arachnids that can wreak havoc on your popcorn plants. These pests feed on plant sap, causing yellowing, stippling, and eventually leaf drop.

Identification:

Spider mites are extremely small and often go unnoticed until significant damage has occurred. They are usually pale yellow, green, or red in color and have eight legs. Look for fine webbing on the leaves and a dusty appearance caused by their shed skins.

Treatment:

To control spider mite infestations, regular monitoring is essential. Spraying your plants with a strong stream of water can help dislodge the mites and reduce their population. Applying insecticidal soaps or horticultural oils can also be effective. Ensure thorough coverage of both the upper and lower surfaces of the leaves.

Cutworms

Cutworms are nocturnal pests that can cause significant damage to popcorn plants. These caterpillars cut through the stem at ground level, causing the plant to wilt and eventually die.

Identification:

Cutworms are usually gray or brown in color and have smooth bodies. They curl up when disturbed and can grow up to 2 inches long. Look for damaged stems near the soil line as a sign of their presence.

Treatment:

To control cutworm infestations, it is important to protect the base of your popcorn plants. Create physical barriers such as cardboard collars or plant seedlings inside small containers with the bottoms removed. This will prevent the cutworms from accessing the stems. Applying insecticides labeled for cutworm control can also be effective.

Conclusion

As a popcorn plant owner, it is essential to be aware of the most common pests that can affect your crop. By learning how to identify these pests and implementing appropriate treatment methods, you can ensure the health and productivity of your popcorn plants. Regular monitoring, good sanitation practices, and the use of natural predators or insecticides when necessary are key to keeping these pests at bay. With proper care, you can enjoy a bountiful harvest of delicious popcorn straight from your own garden.
