Pycnanthus angolensis and Talinum triangulare are among the common valuable plants in West Africa due to their medicinal and nutritional value. This study was aimed at determining the relative toxicity of the ethanol roots extracts of P. angolensis and T. triangulare on B. globosus. Bioassay was evaluated at different concentrations of 160, 320, 480, 640 and 800 pm. Observations were made at 24, 48 and 72 hrs. Mortality of 100 % was recorded for 320 pm concentration of ethanol root extracts of P. angolensis at 72 hrs and 640 pm concentration of T. triangulare at 72 hrs respectively. Through out the duration of the experiment, B. globosus in the controls experiment were active. Based on the result of this present study, the roots of P. angolensis and T. triangulare are recommended as potential agents for the control of B.globosus which is one of the intermediate hosts of urinary schistosomiasis.[Full Text Article]
