Abstract:

The compost samples of button mushroom from Samastipur, Muzaffarpur and Darbhanga districts were processed for the isolation of nematophagous fungi present using serial dilution method on PDA plates. From the button mushroom compost sample of Samastipur district, five fungi viz. Trichothecium roseum, Rhizopus stolonifer, Geotrichum spp., Fusarium spp. and Aspergillus niger were isolated, from Muzaffarpur, only two fungi, Trichothecium roseum and Aspergillus niger were identified and from Darbhanga samples, two fungi, Helminthosporium spp. and Fusarium spp. were identified. From spent mushroom compost the fungi identified were, Trichothecium roseum and Geotrichum spp. From Samastipur district, Trichothecium spp. and Aspergillus niger from Muzaffarpur district and only Helminthosporium spp. was identified from Darbhanga district.

Amongst all the fungi isolated and identified, only three of them were found nematophagous against myceliophagous nematodes. These were Helminthosporium spp., Trichothecium spp. and Geotrichum spp. Helminthosporium spp. and Trichothecium spp. trapped the nematodes through constricting rings while Geotrichum spp. trapped the nematodes through sticky knobs whereas.
