The Root-Knot Nematode is a microscopic roundworm that primarily affects plant roots. It is known for causing significant damage to various crops by forming galls or "knots" on the roots, which disrupts the plant's ability to absorb water and nutrients. This can lead to stunted growth, wilting, and reduced yields. These nematodes thrive in warm, moist soil and can be spread through contaminated soil, water, or plant material. Effective management strategies include crop rotation, resistant plant varieties, and soil fumigation to minimize their impact on agriculture.
