Potency of Piper guineense Linn., Zingiber officinale Rosc., Azadirachta indica A. Juss., Carica papaya Lam. and Nicotiana tabacum Linn. againt in vitro control of Curvularia eragrostide and in vivo inhibitions of rot-causing microorganisms in storage were studied. Rotted Ogoja and Ghini white yam tubers were picked from yam farmers at various locations at Lafia, Nigeria. Rot-causing organisms from Ghini and Ogoja that were isolated for a period of four months included Botryodiplodia theobromae, Aspergillus flavus, A. niger, Fusarium moniliforme, Colletotrichum sp, F. oxysporum, C. eragrostide and Penicillium purpurogenum. Pathogenicity test confirmed all the isolated fungi as rot causing organisms. Result showed that Z. officinale, P. guineense, A. indica, C. papaya and N. tabacum.. View More»
