Abstract

The present study was conducted to evaluate the effectiveness of different disinfectants and protectants in improving sprouting and controlling rotting of yam minisetts. Results revealed that disinfection of both the sprouting medium and yam minisetts increase significantly the percentage sprouting of the Pona minisetts. Benlate was more effective in reducing the incidence of minisett rot and enhanced sprouting of the minisetts in roasted sawdust than the other protectants or disinfectants. Benlate-treated Pona minisetts gave high percentage sprouting and low percentage rotting in the roasted sawdust compare to that of Dente minisetts. Quicklime and neem wood ash were also effective in reducing incidence of minisett rot and increased sprouting of yam minisetts significantly compared with sodium hypochlorite, aqueous neem leaf extract and untreated minisetts (control).
