Plant Parasitic Nematodes: A Critical Challenges for Agricultural Sustainability

Phytonematodes are obligate parasites, meaning they rely entirely into roots of crops or plants for their survival and reproduction or other activity. Phytonematodes can be identified by their specialized or fine feeding structures called stylets—needle-like mouthparts used to pierce plant cells and withdraw nutrients. These nematodes range in size from 0.3 to 3 millimeters and are often invisible to the naked eye, making early detection challenging. Plant parasitic nematodes are a silent but serious threat to global agriculture. Effective management requires early detection, a combination of cultural practices, and the use of resistant crop varieties. By addressing this issue, farmers can safeguard crop productivity and reduce economic losses caused by these microscopic pests.
