Management and control of plant-parasitic nematodes require an integrated approach that combines cultural, biological, chemical, and resistant variety strategies to reduce nematode populations below economic threshold levels while minimizing environmental impact. Nematodes are microscopic roundworms that attack plant roots, leading to stunted growth, chlorosis, reduced yield, and susceptibility to secondary infections. A systematic management plan begins with accurate diagnosis, monitoring, and regular soil sampling to identify the nematode species and assess population density, which is crucial for selecting appropriate control measures. Early detection allows timely intervention and prevents severe crop losses. Cultural practices form the foundation of nematode management. Crop rotation with non-host or resistant crops disrupts nematode life cycles and reduces population build-up in the soil. For example, rotating susceptible crops like tomatoes or potatoes with cereals or legumes can lower root-knot nematode infestation. Sanitation measures, such as removing infected plant debris and avoiding the movement of contaminated soil and tools, prevent the spread of nematodes to healthy fields. Soil solarization, which involves covering moist soil with transparent plastic sheets during hot periods, can effectively kill nematodes in the
