Abstract: Four alkaloidal extracts from Rhazxa stricta and a phenolic extract from Juniperus polycapos were found to possess nematictdal activity against Metoidayvne ,a\anica. At 100ppm concentration, the tested extracts suppressed egg hatching by 4 17-68.92%. The alkaloidal extracts were mare effective than the phenolic extract. Mortality of J2 increased as the extract concentrations increased (LC$o values ranged from 370 to 620ppm). Results were compared with those of the nematicide fenamiphos. Because of the high alkaloidal content °ffL stricta. it could be considered as a promising nematictdal plant
