| Abstract: | Four alkaloidal extracts from Rhazya stricta and a phenolic extract from Juniperus polycarpos were found to posses nematicidal activity against Meloidogyne javanica. At 100 ppm concentration , the tested extracts suppressed egg hatching by 4.17 - 68.92% . The alkaloidal extracts were more effective than the phenolic extract. Mortality of J2 increased as the extract concentrations increased ( LC50 values ranged from 370 to 620 ppm ) . Results were compared with those of the nematicide fenamiphos. Because of the high alkaloidal content of R. stricta , it could be considered as a promising nematicidal plant |
