How to Get Rid of Nematodes on Trailing Ice Plant

Introduction

Nematodes are microscopic worms that can cause significant damage to plants, including the trailing ice plant. These pests feed on plant roots, leading to stunted growth, yellowing leaves, and overall weakening of the plant. If left untreated, nematode infestations can result in the death of the trailing ice plant. However, there are several effective methods to control and eliminate nematodes from your garden. In this article, we will discuss how to get rid of nematodes on trailing ice plants.

1. Crop Rotation

One of the most effective ways to control nematodes is through crop rotation. Nematodes are host-specific, meaning they thrive on specific plants. By rotating your trailing ice plant with plants that nematodes do not prefer, you can disrupt their life cycle and reduce their populations.

Choose plants that are known to be resistant or less susceptible to nematode infestations for rotation. Good options include marigolds, sunflowers, and corn. Ideally, rotate your trailing ice plants with these nematode-resistant crops every two to three years.

2. Solarization

Solarization is another effective method for controlling nematodes in the soil. This process utilizes the sun’s heat to kill nematodes and other soil-borne pests.

To solarize the soil, start by removing any weeds or debris from the area where your trailing ice plants are growing. Water the soil thoroughly to ensure it is moist but not saturated. Cover the area with clear plastic sheeting, securing the edges with rocks or bricks to create an airtight seal.

Leave the plastic sheeting in place for six to eight weeks during the hottest months of the year when the sun’s intensity is at its peak. The heat trapped under the plastic will raise the soil temperature high enough to kill nematodes and their eggs. After the solarization period, remove the plastic and allow the soil to cool before replanting your trailing ice plants.

3. Soil Amendments

Certain soil amendments can help control nematode populations and improve the overall health of your trailing ice plants.

a. Organic Matter: Adding organic matter to the soil, such as compost or well-rotted manure, can reduce nematode populations. Organic matter improves soil structure, promotes beneficial microbial activity, and helps suppress nematode reproduction.

b. Neem Oil: Neem oil is a natural product derived from the neem tree that has shown efficacy in controlling nematodes. Dilute neem oil according to the manufacturer’s instructions and apply it to the soil around your trailing ice plants. The oil disrupts nematode feeding and reproduction, reducing their population over time.

c. Mustard Seed Meal: Mustard seed meal is another effective soil amendment for nematode control. It contains glucosinolates, compounds that release toxic gases when broken down by soil microbes. These gases are harmful to nematodes and can help suppress their populations. Mix mustard seed meal into the soil at a rate of 2-3 pounds per 100 square feet before planting your trailing ice plants.

4. Biological Control

Introducing beneficial organisms into your garden can also help control nematodes naturally.

a. Nematode-Resistant Plants: Some plant species have developed natural resistance to nematodes. By choosing trailing ice plant varieties that are resistant to nematodes, you can reduce the risk of infestation. Look for cultivars specifically bred for nematode resistance when purchasing trailing ice plant seeds or seedlings.

b. Beneficial Nematodes: Certain species of nematodes are predatory and feed on plant-parasitic nematodes. These beneficial nematodes can be purchased and applied to the soil around your trailing ice plants. Follow the instructions provided by the manufacturer for application rates and timing.

5. Chemical Control

Chemical control should be considered as a last resort, as it can have negative impacts on the environment and beneficial organisms. However, in severe infestations, it may be necessary to use chemical nematicides.

Consult with a professional or local extension office for guidance on appropriate chemical treatments for nematode control on trailing ice plants. Always follow the instructions provided by the manufacturer and take necessary precautions to protect yourself, other plants, and the environment.

Conclusion

Nematodes can pose a significant threat to trailing ice plants, but with proper control methods, their populations can be managed effectively. Implement crop rotation, solarization, soil amendments, biological control, and chemical control when necessary to protect your trailing ice plants from nematode infestations. By taking proactive measures and maintaining healthy growing conditions, you can ensure the long-term success of your trailing ice plant garden.
