What is a significant feature of the root-knot nematode?

The significant feature of the root-knot nematode is that it causes root swelling and stunting of plants. This nematode, a microscopic worm, infects the roots of a variety of plants, leading to the formation of galls or "knots" on the roots. This physical damage impairs the plant's ability to absorb water and nutrients, ultimately leading to stunted growth. As the nematode population increases, the health of the host plants declines, which can result in reduced yields and overall poor plant performance. Understanding this impact is critical for effective pest management and for maintaining healthy plant ecosystems.
