How to Get Rid of Nematodes on Chamomile Plant

Updated: April 2, 2022

Chamomile is a popular herb known for its calming properties and medicinal benefits. However, like any other plant, chamomile is susceptible to pests and diseases, including nematodes. Nematodes are tiny, microscopic worms that live in the soil and feed on plant roots, causing stunted growth, yellowing leaves, and eventually plant death. If you have noticed these symptoms on your chamomile plant or suspect nematodes, here are some tips on how to get rid of them.

Identify the Type of Nematode

There are different types of nematodes that can infect chamomile plants. The most common ones are root-knot nematodes and lesion nematodes. Root-knot nematodes cause the roots to swell into galls or knots, while lesion nematodes create small lesions or wounds on the roots. Identifying the type of nematode is crucial in choosing the appropriate treatment.

Practice Crop Rotation

Crop rotation is an effective way to prevent nematode infestation in your chamomile plants. Nematodes thrive in the soil, so by rotating your crops with non-host plants, you can reduce their population and prevent them from infecting your chamomile plants. Some non-host plants include marigold, wheat, and barley.

Use Beneficial Nematodes

Believe it or not, not all nematodes are harmful to plants. In fact, there are beneficial nematodes that can prey on harmful ones and help control their population. These beneficial nematodes are called entomopathogenic nematodes and can be purchased from garden centers or online stores. To use them, mix them with water and apply them to the soil around your chamomile plants.

Apply Organic Soil Amendments

Organic soil amendments such as compost, manure, and worm castings can improve the soil quality and make it less hospitable for nematodes. These amendments release beneficial microorganisms that can compete with nematodes for food and space. Additionally, they can boost the plant’s immune system and help it resist nematode infestation.

Use Nematicides

If all else fails, you can use nematicides to kill nematodes on your chamomile plants. Nematicides are chemical substances that are toxic to nematodes and can be applied directly to the soil. However, nematicides can be harmful to the environment and other beneficial organisms in the soil, so use them with caution and follow the instructions carefully.

Frequently Asked Questions

Can nematodes be completely eradicated from the soil?

It’s challenging to completely eradicate nematodes from the soil because they have a high reproductive rate and can survive adverse conditions. However, you can control their population by using the methods mentioned above.

How often should I rotate my chamomile plants with non-host crops?

It’s recommended to rotate your chamomile plants with non-host crops every two to three years.

Can I reuse the soil from an infected chamomile plant?

It’s not recommended to reuse the soil from an infected chamomile plant because it may contain nematodes and other harmful organisms that can infect new plants. Instead, replace the soil or sterilize it before using it again.

Are nematicides safe for human consumption?

Nematicides can be harmful to human health if ingested or inhaled. It’s important to follow the instructions carefully when using them and avoid harvesting or consuming the treated plants for a certain period specified on the label.

In conclusion, nematodes can be a nuisance for chamomile growers, but there are several ways to control their population and prevent them from infecting your plants. By identifying the type of nematode, practicing crop rotation, using beneficial nematodes, applying organic soil amendments, and using nematicides as a last resort, you can keep your chamomile plants healthy and thriving.
