Eighteen mung bean seed samples collected from thirteen districts of Karnataka were tested for mycoflora by employing standard blotter method which revealed the association of twelve fungi viz., Aspergillus niger, Alternaria alternata, Aspergillus flavus, Aspergillus candidus, Penicillium notatum, Rhizopus stolonifer, Cladosporium sp., Fusarium oxysporum, Mucor sp., Curvularia lunata, Macrophomina phaseolina and Chaetomium globosum. Seed samples collected from Kalaburagi, Raichur and Bagalkot districts recorded the highest mycoflora. Seeds of mung bean genotypes grown in kharif recorded highest association of seed mycoflora compared to rabi. Among different incubation methods employed, blotter method was found ideal in enumerating seed mycoflora. Location of mycoflora in mung bean seeds showed that A. flavus was confined to both seed coat and cotyledons, whereas Fusarium to embryo. Survival of mycoflora on mung bean seeds revealed that field fungi decreased after eight months of storage whereas storage fungi increased. Hot water treatment at 40 °C for 30 minutes was found best in managing seed mycoflora followed by solar heat treatment and dry heat treatment. Seed treatment with captan at the rate 4 g kg-1 of seed significantly reduced seed mycoflora (78.68 %). Seed treatment with Trichoderma harzianum at the rate of 8 g kg-1 of seed reduced the seed mycoflora up to (69.63 %) followed by Pseudomonas fluorescences (66.49 %) and T. viride (64.39 %).ennullThesis
