What do nematodes primarily feed on?

Nematodes are a diverse group of microscopic roundworms, and many species primarily feed on plant roots. This feeding behavior can lead to significant damage in agricultural and horticultural settings, as the nematodes invade the roots, which can result in reduced nutrient and water uptake for the plant. The disruption of the plant's root system can stifle growth, cause wilting, or even lead to plant death, illustrating the impact nematodes can have on crop yield and health.

While nematodes can also be associated with other food sources—such as bacteria, fungi, or even insects—many of the detrimental species that affect crops are those that specifically target plant roots. Understanding this feeding behavior is crucial for effective pest management and developing appropriate control strategies in agriculture.
