This study was carried out to investigate the effects of Neem (Azadirachta indica A. Juss.) seed oil on four fungi, namely: Fusarium sp. Rhizopus sp. Curvularia sp. and Aspergillus sp. which are pathogenic in nature. The crude extract of neem seed was obtained using petroleum ether. The extract inhibited the growth of all the fungi tested. The extent to which the extract inhibited the growth of the fungi was observed to be different for each of the fungi. Growth inhibition was highest in Curvularia sp. (which did not grow beyond the initial point of its radial growth before introduction of the extract), while the lowest effect was observed in Rhizopus sp.
