Nematodes are microscopic roundworms that primarily feed on the roots and other underground parts of plants. Their feeding habits can lead to significant damage to the plant's root system, affecting its ability to absorb water and nutrients from the soil. This feeding can result in stunted growth, poor plant health, and even plant death in severe cases.

Roots are particularly vulnerable because nematodes can introduce pathogens and cause root lesions, which further complicates the plant's situation by promoting secondary infections. Since most nematodes thrive in soil, their impact remains mainly underground, where they can evade certain types of pest control measures that target above-ground plant parts. Hence, understanding the focus of nematode attacks on roots and underground parts helps in developing effective management strategies.
