Phytoparasitic nematodes are highly dangerous to the global agricultural production of a variety of crops. Chemical nematode overuse necessitates the creation of new nematode control strategies. Filamentous fungi could be a feasible biocontrol alternative in this case. Trichoderma, mycorrhizae, and endophytic fungi are the most common filamentous fungi studied and used as biological control agents (BCAs) against nematodes as resistance inducers. Several pathways have been linked to the biocontrol effect of fungi on plant-parasitic nematodes. Increased plant tolerance, direct competition for nutrients and space, induced systemic resistance (ISR), and altered rhizosphere interactions are all possible pathways. Several mechanisms, as well as a detailed discussion of their plausibility in the biocontrol of plant-parasitic nematodes, in particular, have been postulated. Mycorrhizal fungi are not yet widely utilized in conventional agriculture, but recent data is assisting in the development of a better understanding of the mechanisms of action. This will eventually lead to mycorrhizal fungi being used in the field to combat plant-parasitic nematodes.
