Plant-parasitic nematodes are microscopic roundworms that cause significant damage to agricultural and horticultural crops worldwide. These covert pests cause significant financial losses by lowering crop quality, yield, and market value. With the rapid growth of international trade in plants, seeds, bulbs, and other planting materials, the risk of spreading harmful nematode species across borders has increased considerably, Invasive nematodes can spread quickly, endanger local crops, and become challenging and expensive to control once they are introduced into a new area. As a result, plant quarantine is essential to stopping their introduction and spread. Prior to import or export, plant materials must be inspected, tested, certified and treated in accordance with quarantine rules. Effective quarantine policies support safe international trade, preserve biodiversity, and safeguard domestic agriculture. Increased awareness, advanced diagnostic techniques, and strong international cooperation are essential for managing nematode risks and ensuring global food security, and sustainable agricultural development all depend on increased awareness, sophisticated diagnostic methods, and robust international cooperation.
