Prevalence of fungi associated with storage seeds of different maize varieties

A total of seven species of fungi were isolated from seed samples of maize (Zea mays L.) collected from Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur. Association of fungi with maize seeds was recorded three times viz., within a month after harvest, after three and six months of storage at 25°C and 4°C. The fungal association varied with duration of storage period. Seven fungi viz., Aspergillus flavus Link, A. fumigatus Fresenius, A. niger Van Teighem, Curvularia lunata (Wakker) Boedijn, Fsarium verticillioides, Penicillium italicum and Rhizopus stolonifer (Ehrenb.) Vuill., were isolated from the different maize varieties namely KhaiBhutta, Barnali, Mohor, Bari Misty Bhutta, BHM-3, BHM-5, BM-5, BHM-6, BHM-7, BM-7 and BHM-9. Species of Aspergillus, Penicillium and Rhizopus were predominating fung iwhich increased with the increase of storage period.

Indoor fungi on damp walls of buildings and their management

A total of eight species of fungi and one sterile fungus were isolated from the indoor damp walls. The fungi were Aspergillus flavus Link, A. fumigatus Fresenius, A. niger van Teighem, A. niger (culture type 1), A. terreus Thom, A. terreus (culture type 1), A. ustus, Fusarium sp., Penicillium sp. Ulocladium sp. and a fungus with sterile mycelia. The frequency percentage of association of A. fluvus, A. fumigatus and A. niger was higher than any other fungi. This is the first report of association of fungi in indoor damp walls from the Department of Botany, University of Dhaka and a private house of Dhaka city. Effects of six fungicides were evaluated against the isolated fungi. Bavistin and tall were found most effective against the radial growth of the damp wall fungi.
