What is the most common plant parasitic nematode that affects plants?

Root Knot nematodes are recognized as the most prevalent plant parasitic nematodes impacting a wide range of plants. These microscopic roundworms invade the root systems of various crops and ornamental plants, causing the characteristic galls or ‘knots’ that can be seen on affected roots. This galling disrupts normal water and nutrient uptake, leading to stunted growth, wilting, and overall decline of the plant health.

These nematodes have a broad host range, affecting many economically significant plants, which magnifies their impact in agricultural settings. Their ability to reproduce quickly and thrive in diverse soil conditions further contributes to their prevalence in both agricultural and ornamental horticulture. In contrast, other nematodes, such as foliar nematodes or stem gall nematodes, may affect different parts of the plant or have less widespread economic significance, making root knot nematodes the most commonly encountered type. Understanding the life cycle and management strategies for root knot nematodes is crucial for effective pest control and maintaining healthy plants.
