Studies on the antimicrobial potency was carried out on five crude plant extracts (Piper nigrum, Zingiber officinale, Azadirachta indica, Carica papya and Nicotiana tabacum) and a chemical fungicide (mancozeb) using three concentrations of hot aqueous plant extracts (30, 60 and 90 g/l) and mancozeb (4, 8 and 12 g/l). The extracts and chemical were separately amended in potato dextrose agar (PDA) in in vitro control of Aspergillus flavus; causal agent of yam tuber rot. Rotten white yam tubers were collected from farmers’ barns at various locations in the study area and taken to Advanced Plant Pathology Laboratory, Federal University of Agriculture, Makurdi, Nigeria for analyses. A. flavus was isolated and identified from the rotten white yam tubers; pathogenicity test was carried out to confirm the actual organism associated with the rot in yam. The test revealed that A. flavus was able to incite rot in the healthy yam tubers. The results further showed that all the test plants were able to significantly (p
