How to Get Rid of Nematodes on Mums Plant

Updated: July 18, 2023

Nematodes are microscopic worms that can cause significant damage to plants, including mums. These pest organisms live in the soil and feed on plant roots, leading to stunted growth, wilting, and even death of the affected plant. If you notice your mums plant struggling and suspect nematode infestation, it is crucial to take action promptly to prevent further damage. In this article, we will explore effective methods to get rid of nematodes and protect your mums plant.

Diagnosing Nematode Infestation

Before you begin treatment, it is essential to confirm if your mums plant is indeed infested with nematodes. Look for signs such as stunted growth, yellowing or wilting leaves, and the presence of small knots or galls on the roots. You can also dig up a small section of the root system and examine it closely for any signs of nematodes.

If you are unsure about the presence of nematodes, consult a local extension service or a professional gardener who can help you diagnose the issue accurately.

Cultural Practices to Control Nematodes

Implementing proper cultural practices can help manage nematode populations and reduce their impact on your mums plant. Here are some techniques you can incorporate:

Crop Rotation

Nematodes often have specific host plants they prefer. By rotating your mums with non-host plants, you can disrupt the nematode life cycle and reduce their numbers. Choose plants that are not susceptible to nematode infestation, such as marigolds, corn, or sweet potatoes. Rotate crops every two to three years to break the cycle effectively.

Soil Solarization

Soil solarization is a technique that utilizes the sun’s heat to kill nematodes and other soil-borne pests. Start by clearing the area around your mums plant and watering the soil thoroughly. Cover the area with clear plastic, making sure it is tightly sealed around the edges. Leave the plastic in place for four to six weeks during the hottest period of the year. The heat trapped under the plastic will raise the soil temperature, effectively killing nematodes and other pests.

Healthy Soil Management

Maintaining healthy soil is crucial in preventing nematode infestation. Ensure your mums plant is growing in well-drained soil that is rich in organic matter. Add compost or well-rotted manure to improve soil fertility and promote beneficial soil microorganisms that can naturally suppress nematodes.

Biological Control for Nematodes

Biological control involves using natural enemies to keep nematode populations in check. Several beneficial organisms can help control nematodes effectively:

Nematophagous Fungi

Certain species of fungi are known to feed on nematodes. These fungi, such as Paecilomyces lilacinus and Hirsutella rhossiliensis, can be applied to the soil around your mums plant to reduce nematode numbers. Follow the instructions on the product label for application rates and timing.

Parasitic Nematodes

Parasitic nematodes, such as Heterorhabditis bacteriophora and Steinernema feltiae, are natural predators of plant-parasitic nematodes. These beneficial nematodes can be purchased from garden centers or online suppliers. Mix them with water according to the instructions provided and apply the solution to the affected area. The parasitic nematodes will seek out and infect the harmful nematodes, reducing their population.

Chemical Control Options

If cultural practices and biological control methods are not sufficient to manage nematode infestation, chemical control may be necessary as a last resort. It is important to note that chemical treatments should only be used when other options have failed, as they can have negative impacts on the environment and beneficial organisms. Always follow the instructions on the product label and wear appropriate protective gear when using chemical pesticides.

Nematicides

Nematicides are chemical pesticides specifically formulated to control nematodes. They can be applied to the soil around your mums plant to kill nematodes and prevent further damage. However, it is essential to choose a nematicide that is labeled for use on mums plants and follow the instructions carefully.

Conclusion

Nematodes can pose a significant threat to your mums plant, but with proper management techniques, you can effectively control their population and protect your plant’s health. Start by implementing cultural practices such as crop rotation and soil solarization. Incorporate biological control methods using nematophagous fungi and parasitic nematodes. If necessary, consider chemical control options as a last resort. Remember to always follow the instructions provided and consult with professionals if needed. By taking proactive measures, you can ensure the long-term health and vitality of your mums plant.
