Nematodes

What are they?

Just a handful of soil can contain thousands of these microscopic worms, which attack at plant roots. Many them act as parasites on animals, plants and pollinators. They penetrate the roots of the plant and absorb water and nutrients from the root system, thus damaging the plant. They reproduce and swell up, which is known as root galling.

Nematodes can be invasive when not implemented for biological controls, such as the potato cyst, which leads to significant yield and crop loss of fruit and vegetables. Nematodes can be identified aboveground in the vegetation through undeveloped or distorted plant growth. However, due to the minute nature of nematodes, it is necessary to carry out a microscopic examination.

How to get rid of nematodes?

As the nematode pest is microscopic it is highly difficult to eliminate. Suggested are a few remedies that can eradicate the pest.

  • Removing the diseased plants and seedings infested by nematodes can eliminate the pest.
  • Infected materials and equipment require hot-water treatments and possibly insecticidal coatings.
  • Nematicides maybe necessary on the plant roots to kill off the pest directly.

How to prevent nematodes?

There are a number of ways to prevent the occurrence of nematodes, such as:

  • Cleaning farm machinery between fields, to prevent the spread from infested to unaffected fields.
  • On agricultural fields ensure crop rotation, or to best prevent nematode occurrence, stop production altogether during the summer months.
  • Sow green manures to cover up bare soil or use cover crops to manage soils erosion.
  • Before planting apply soil fumigations to control nematodes before the occupy.
