Interaction of nematodes with nematophagus fungi: induction of trap formation, attraction and detection of attractants. The interaction between root-lesion nematodes and the pathogenic fungus Rhizoctonia solani Kühn was studied on potato plants grown in pots under controlled conditions. 1) Nematode- fungus interactions Atkinson (1892) was the first to observe the involvement of nematodes in disease complexes when he recorded increased severity of cotton wilt caused by Fusarium oxysporum f.sp. Addition of fungal—feeding nematodes did not increase plant growth or N uptake because these nematodes excreted less NH 4 + —N than did bacterial—feeding nematode populations and because the N mineralized by the fungus alone was sufficient for plant growth. Since the publication of Atkinson’s report (1892) that Fusarium wilt of cotton was more severe in the presence of root-knot nematode (Meloidogyne spp.) than in its absence, a large volume of data has been accumulated to date which firmly establishes the involvement of plant-parasitic nematodes in interactions with fungal plant pathogens on various crop plants (Powell, 1971, 1979; Bergeson, 1972; … The nematodes, like many other soil inhabitants, secrete chemicals as they travel through the soil. are well known in literature for their role in control of plant parasitic nematodes.

The authors consider fungal-nematode interactions, fossil fungi, the biodiversity, ecology and geographical distribution of nematode-trapping fungi, and their potential use in biocontrol of nematodes, all in detail. Arthrobotrys oligospora forms so-called adhesive network traps on which vermiform nematodes are captured. Fungi and nematodes are among the most abundant organisms in soil habitats. Krizkova The isolation of tolerant beneficial organisms from contaminated soils may be an ideal way to achieve soil decontamination goals. The mechanisms operating in these interactions are largely unknown. The dynamics of these organisms is especially important given the pathogenicity of nematodes and, consequently, the potential application of nematode-trapping fungi as biocontrol agents. Nematode-trapping fungi develop complex trapping devices to capture and consume nematodes. Nematodes can feed on fungi, and conversely fungi can use nematodes as a food source.

Bacteria, fungi, and both trophic groups of nematodes were more abundant in the rhizosphere than in nonrhizosphere soil.

Nemec were isolated from an alluvial soil planted with paddy-rice and wheat in subtropical region. D. Antagonistic Interactions Antagonistic interactions between fungi and nema todes are as numerous as they are varied. The combination of nematode and fungus often results in a synergistic interaction wherein the crop loss is greater than expected from either pathogen alone or an additive effect of the two together. The result for a cultivar sensitive to the interaction can be total crop failure. Therefore interaction with other biocontrol agent specially entomopathogenic fungi … Ranieri Nematode – fungus interaction was first observed by Atkinson (1892) in cotton. nematodes are suggested to contribute to the turnover and changes in the structure and functioning of soil AMF community [8].
