Uncinariidae
The family Uncinariidae belongs to the class Nematoda, order Strongylida. While typically recognized as parasites of animals, in an agronomic sense, these nematodes are significant components of soil biodiversity that can indirectly influence plant health and root development in high-intensity farming environments.

Uncinariidae
These organisms are microscopic parasites with a life cycle heavily dependent on soil moisture and temperature. Larval stages are highly mobile in the soil profile, which allows them to migrate towards the root zones of host plants, where they can survive in the rhizosphere and interact with the crop's root architecture.
Crop damage occurs primarily through the physical impact on the root system. By feeding on root tissues, these nematodes cause mechanical injuries that impair the plant's ability to uptake water and essential minerals. This leads to stunted growth, nutrient deficiencies, and reduced overall plant vigor, significantly impacting economic yield.
The severity of an infestation is often exacerbated by the presence of secondary soil pathogens. When the roots are damaged by nematodes, they become highly susceptible to fungal and bacterial infections, leading to rot and rapid decline of the affected plants, which creates patchy areas of poor growth within the field.
Effective protection strategies focus on soil sanitation and habitat management to break the nematode life cycle. Recommended practices include:
- implementing crop rotation with non-host species;
- using soil solarization in greenhouses to reduce populations;
- applying organic amendments to boost beneficial soil microflora;
- maintaining optimal irrigation to prevent waterlogging, which favors migration.
