Most Common Mum Plant Pests:
Identification and Treatment Guide

Mums, also known as chrysanthemums, are popular flowering plants that bring beauty and color to gardens and indoor spaces. However, like any other plant, mums are susceptible to pest infestations that can damage their health and appearance. In this article, we will discuss the most common mum plant pests, how to identify them, and effective treatment methods.

1. Aphids

Aphids are tiny, soft-bodied insects that suck sap from mum plants, causing leaf distortion, yellowing, and stunted growth. These pests are usually found in clusters on the undersides of leaves or near new growth. To identify aphids, look for small green, black, or brown insects with pear-shaped bodies.

To control an aphid infestation, you can start by spraying the affected plants with a strong stream of water to dislodge the pests. Alternatively, you can use insecticidal soap or neem oil spray to eliminate aphids. Ensure thorough coverage of both sides of the leaves and repeat treatments every 7-10 days until the infestation is under control.

2. Spider Mites

Spider mites are tiny pests that feed on mum plants by piercing the leaves and sucking out the sap. They leave behind small yellow or white specks on the leaves and produce fine webbing on the affected parts of the plant. If left untreated, spider mite infestations can cause severe leaf damage and even death of the mum plant.

To identify spider mites, carefully inspect the leaves for tiny specks or stippling marks. You may also notice fine silk webbing on the plant. Since spider mites reproduce rapidly, it is crucial to take immediate action if an infestation is detected.

To treat a spider mite infestation on mums, start by spraying the affected plants with a strong stream of water to remove the pests. Additionally, you can apply insecticidal soap or neem oil spray, ensuring complete coverage of both sides of the leaves. Repeat treatments every 3-5 days until the infestation is eradicated.

3. Whiteflies

Whiteflies are tiny, winged insects that gather on the undersides of mum plant leaves. They feed on the sap and excrete a sticky substance called honeydew, which can attract ants and promote the growth of sooty mold. Infested plants may display yellowing leaves, stunted growth, and a general decline in health.

To identify whiteflies, look for small, white insects that fly up when the plant is disturbed. You may also notice the presence of honeydew or black sooty mold on the leaves.

To control whitefly infestations, you can start by using a handheld vacuum cleaner to physically remove the pests from the plant. Alternatively, you can use yellow sticky traps to catch adult whiteflies. For severe infestations, consider using insecticidal soap or neem oil spray, applying it thoroughly to the affected plant parts.

4. Caterpillars

Caterpillars are larvae of various moth species that feed on mum plants’ foliage, causing extensive damage. They chew through leaves and create large holes or skeletonize them, leading to reduced plant vigor and overall aesthetic appeal.

To identify caterpillar damage, look for irregular holes or chewed edges on mum plant leaves. You may also spot caterpillars themselves, which vary in appearance depending on the species.

To control caterpillar infestations, manually remove any visible caterpillars from the plant and dispose of them properly. If necessary, you can also apply Bacillus thuringiensis (Bt), an organic insecticide specific to caterpillars. Follow the product instructions carefully for effective control.

5. Slugs and Snails

Slugs and snails are common garden pests that can damage mum plants by chewing through leaves and stems. They are most active during damp weather and often feed at night, leaving behind slime trails as evidence of their presence.

To identify slug or snail damage, look for irregular holes or ragged edges on mum plant leaves. You may also notice slime trails on the ground or surrounding surfaces.

To control slug and snail infestations, you can start by physically removing them from the garden. You can also create barriers using crushed eggshells, diatomaceous earth, or copper tape around the plants to deter these pests. Additionally, consider using organic slug and snail baits or traps to control their population.

In conclusion, mum plants can be plagued by a variety of pests that can impact their health and appearance. By promptly identifying these common pests and taking effective treatment measures, you can ensure the vitality and beauty of your mum plants. Remember to use organic or chemical treatments responsibly, following the instructions to protect both the plants and the environment.
