Abstract: The molluscicidal effect of seven different concentrations of ethanolic extract of Ocimum gratissimum (Scent leaf) against ten adult Bulinus globosus was investigated under laboratory conditions. The snails, collected from the vegetation at the banks of the streams in Anyu, Obedum and Emirikpoko communities in Abua/Odual Local Government Area, Rivers State, using a scoop net and some snails also hand-picked from vegetation where possible, were introduced simultaneously into appropriately labelled 1000ml beakers containing the different extracts' concentrations of O. gratissimum. The liquid extract obtained from 1kg dried and powdered leaf of O. gratissimum, exhaustively.....
