How to Get Rid of Nematodes on Combo Plant

Updated: October 25, 2022

If you are an avid gardener, then you know how frustrating it can be to have a nematode infestation on your combo plants. Nematodes are microscopic roundworms that live in soil and feed on plant roots, causing stunted growth, yellowing leaves, and even death. However, there are several methods that you can use to get rid of nematodes on your combo plants. Here are some tips to help you out.

Identify the nematodes

Before you begin any treatment method, it is essential to identify the type of nematodes that have infested your combo plant. There are many types of nematodes, but the most common ones that attack combo plants include root-knot nematodes, lesion nematodes, and dagger nematodes. You can take a soil sample to a local nursery or agricultural extension office to have it tested for nematode species.

Crop rotation

One of the best ways to control nematode populations is by practicing crop rotation. Nematodes are host-specific, which means they can only survive on certain plant species. Therefore, rotating your crops will limit the number of nematodes in the soil. You can replace your combo plants with non-host crops such as legumes and grasses for a season or two.

Soil solarization

Soil solarization involves covering moist soil with plastic for several weeks during hot summer months. The heat generated under the plastic will kill most of the nematodes in the soil. This method is effective in reducing nematode populations before planting combo plants.

Organic amendments

Adding organic matter such as composted manure, leaf mold, or biochar to your soil can also help reduce nematode populations over time. Organic matter provides food for beneficial microorganisms that prey on nematodes and improve soil health.

Chemical treatments

If nematode populations are high, you may need to use chemical treatments. There are several nematicides available in the market that can control nematodes. However, these chemicals can be toxic to beneficial soil organisms and can harm the environment. Always follow the manufacturer’s instructions and use protective gear when applying chemical treatments.

Companion planting

Companion planting involves growing plants that repel or trap nematodes near your combo plants. Some good companion plants for nematode control include marigolds, mustard greens, and sunflowers. These plants release chemicals that repel nematodes or have root systems that trap nematodes.

Conclusion

Nematodes can cause significant damage to your combo plants, but there are several methods that you can use to control them. Crop rotation, soil solarization, organic amendments, chemical treatments, and companion planting are all effective ways to reduce nematode populations in your soil. By following these tips, you can protect your combo plants from nematode infestations and ensure a healthy harvest.
