This study investigates the use of botanical extracts (Piper guineense , Xylopia aethiopica and Bambusa vulgaris at 5, 10 and 15% concentration levels) for controlling deteriorating fungal pathogens in vitro . Identification of the fungal pathogens after pathogenicity test reaffirm isolates identity as Fusarium oxysporum , Fusarium solani , Macrophomina phaseolina , Fusarium verticillioides and Botryodiplodia theobromae. All the fungal pathogens induced rot in the watermelon fruit . The botanical extracts were best effective at high concentration levels (10 and 15%), though varied in their inhibitory activity. P. guineense and X. aethiopica were observed to be more effective than B. vulgaris . This study showed the efficacy of the botanical extracts on deteriorating fungal pathogens of watermelon fruit. Thus, the botanical extracts can be employed as antideteriorating biological-based fungicides for watermelon fruits.
