- semi-endoparasitic nematodes that insert their heads in the roots of plants but the body is outside the roots.
- Ectoparasitic nematodes that live outside the roots of the plant but with the stilet able to suck the liquid root of the plant.
- Endoparasit nematodes are nematodes that live completely in plant roots.
The presence of nematode attack on the roots can be marked by the presence of symptoms that appear on the roots or parts of plants above the soil surface.
Roots filled with endoparasitic or semi-endoparasitic nematodes will react by forming tumors or large boils such as tubes. The wounded nematode attack can be infected with the femoral femme causing secondary disease.
With unhealthy roots the distribution of nutrients becomes choked up. As a result, stunted plant growth, dwarf, chlorosis and often followed by wilting, deciduous leaves, or dead plant tip. Another consequence of Nematode attack is the growing point of abnormalities so that the leaves are curly, bent, twisted, or stalked.
The toxins that can control these nematodes are called nematicides. Generally nematisida shaped granules whose use can be sown or embedded in the soil. However, there is also a solution in the water which its use by splashing.
