What are plant parasitic nematodes?

Plant parasitic nematodes are indeed small roundworms that primarily inhabit soil and are associated with plant roots. These nematodes specifically feed on the cells of plant roots, often leading to significant damage to the plants, which can result in stunted growth, wilting, and reduced yields. They can disrupt nutrient and water uptake, making them particularly problematic in agricultural and turfgrass settings.

The context of their biological role is crucial; nematodes themselves are not insects, fungi, or viruses and do not function in those capacities. Understanding the biology of plant parasitic nematodes helps in recognizing their method of damaging plants and the management strategies that are required to mitigate their impact. By distinguishing them from other pests and pathogens, effective pest management practices can be developed that target these specific organisms and protect plant health.
