Abstract

 

Investigation was carried out to test the potency of some plant extracts for the control of yam tuber rot caused by Fusarium oxysporum, Aspergillus niger and Aspergillus flavus. Hot water extracts were obtained from leaf and seed of uda (Xylopia aethiopica) and Ginger (Zinigiber officinale), and were found to be fungitoxic against the fungi. The extracts of suppressed the growth of these fungi in culture and reduced rot development in yam tubers.

 

Key words: Xylopia aethiopicaZinigiber officinale, ginger, yam tuber rot.
