  Comparatives studies of the potency of seeds of Piper guineense Schumach. (Black peper), rhizomes of Zingiber officinale Rosc. (Ginger), leaves of Azadirachta indica A. Juss. (neem), leaves of Carica papaya Lam. (pawpaw) and leaves of Nicotiana tabacum Linn. (Tobacco) were tested against growth of F. solani in vitro. Pathogenicity tests were carried out on Botryodiplodia theobromae, Aspergillus flavus, A. niger, A. ochraceus, Fusarium moniliforme, F. oxysporum, F. solani, Curvularia eragrostide and Colletotrichum sp which confirmed that all the fungi organisms elicited rot on healthy Hembankwase cultivar. In vitro tests of the different plant extracts on F. solani at 30 g/L, 60 g/L and 90 g/L revealed that all the extracts were fungitoxic. However, P. guineense and Z. officinale were more potent compared with A. indica, C. papaya and N. tabacum. The synthetic fungicide mancozeb consis.. View More»
