| Abstract | ||||
| Plant-parasitic nematodes (PPNs) are a massive group of animals that feed on plant tissue and cause a reduction in yield quantity and quality. PPNs affect plants directly by infecting the plant or indirectly breaking the plant's resistance to other pathogens and/or synergistically with different pathogens, causing complex diseases. Additionally, PPNs sometimes carry plant pathogens as viruses and transmit them to hosts. Many strategies were employed to manage PPNs. Biological control is considered the main strategy for controlling PPNs, alternatively to nematicides, which cause harmful effects on humans, the environment, and beneficial microorganisms. Fungi, bacteria, viruses, actinomycetes, mites, predatory nematodes, protozoa, and yeasts were utilized successfully for managing PPNs. These bioagents suppress nematode populations through a variety of direct and indirect mechanisms. These environmentally benign strategies are being progressively incorporated integrated into integrated pest management (IPM) systems to reduce reliance on chemical nematicides and support sustainable agriculture. In this review, the benefits, drawbacks, limitations, and overcomes of applying biological control strategies against PPNs have been discussed and summarized. | ||||
