The harm caused by root-knot nematodes in potted flowers

Root-knot nematodes are tiny nematodes that mainly attack the roots of plants. After infestation, the roots will show symptoms such as rotting, blackening, and decay. In severe cases, the plant may grow slowly, leaves may turn yellow, wither, and even die. According to statistics, the annual loss of plants worldwide caused by root-knot nematodes amounts to several billion dollars.

Identification of root-knot nematodes in potted flowers

1. Observe the roots: Infested roots will show symptoms such as rotting, blackening, and distortion.

2. Observe the leaves: Leaves will show symptoms such as yellowing, withering, and falling off.

3. Observe the soil: The soil will become compacted, dry, and have low organic matter content.

Control methods for root-knot nematodes in potted flowers

1. Choose healthy plants: When purchasing potted flowers, select plants with well-developed roots and no diseases.

2. Improve the soil: Use decomposed organic fertilizers and an appropriate amount of chemical fertilizers to enhance soil fertility and the plant's resistance to diseases.

3. Rotate crops: Avoid planting the same plant continuously in the same plot to reduce the reproduction of root-knot nematodes.

4. Soil disinfection: Use 50% carbendazim wettable powder or 50% dicamba wettable powder for soil disinfection, with a dosage of 100-150 grams per square meter.

5. Biological control: Utilize natural enemies of root-knot nematodes, such as nematode fungi and nematode viruses, to suppress their reproduction.

6. Chemical control: In the early stages of the disease, use 5% abamectin emulsion or 1.8% abamectin emulsion for root irrigation, with a dosage of 200-300 milliliters per mu.
