Control of yam tuber rot with leaf extracts of Xylopia aethiopica and Zingiber officinale

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.
