Experiments were carried out in the laboratory to evaluate the effects of aqueous extracts of leaves, seeds and roots of Datura stramonium at different concentrations on mortality of Globodera rostochiensis juveniles. Volumes of 5 mL of the extract at 100 (crude extract), 50, 25 and 12.5% dilutions were dispensed separately into Petri dishes containing 20 freshly hatched second stage juveniles (J2s) of G. rostochiensis. Juvenile mortality was recorded at 24, 48 and 72 h intervals.
