Survey was conducted during 2014-15 for the isolation of mycoflora from the egg masses of Meloidogyne incognita infecting crops like tomato, brinjal, pea and ameranthus from five different locations viz., Charigaon, Alengmora, Danichopari, Namdeori and Barbheta of Jorhat and Golaghat district of Assam. The egg masses were collected and surface sterilized in 0.4 per cent sodium hypochlorite (NaOCl) for two minutes. Further these egg masses were washed thoroughly with sterile distilled water until the traces of NaOCl was removed and placed in potato dextrose agar plate. The inoculated pertriplates were incubated at 25±2oC in BOD incubator for 4 days. A pure culture of each isolate was made by using hyphal tip technique. A total of 29 fungal isolates comprising of 7 genera with 9 species viz. Trichoderma harzianum, Paecilomyces niphetodes, Acremonium falciforme, Fusarium oxysporium, F. solani, Aspergillus niger, A. flavus, Vermispora leguminacea, Penicillium spp. and an unidentified species were recovered. All the species showed varied relative frequency of occurrence, F. oxysporum being the most frequently occurred species with 31.03 per cent of total fungal isolates.
