Abstract:
The study was carried out at the Molecular Plant Pathology Laboratory,
Department of Plant Pathology, Faculty of Agriculture, Sher-e-Bangla
Agricultural University, (SAU), Dhaka-1207, during the period of January to
June, 2017 to isolate the mycoflora from different mushroom substrates and to
evaluate their biological activities against selected pathogens (Fusarium
oxysporum, Sclerotium rolfsii, Colletotrichum corchori). For this purpose three
types of mushroom substrates viz. sawdust, rice straw and newspaper were used.
Four fungi were isolated and identified from mushroom substrates. These were
Aspergillus flavus, Aspergillus niger, Trichoderma harzianum, and Penicillium
sp. In in-vitro dual culture method Trichoderma harzianum showed the best
performance in reducing radial mycelial growth of the selected pathogenic fungi,
whereas Penicillium sp showed the least significant result against these
pathogens. T. harzianum showed the highest inhibition in case of Fusarium
oxysporum (71.62%) followed by Sclerotium rolfsii (61.64%) and
Colletotrichum corchori (57%).
