| Abstract | ||
| Aqueous extracts of black nightshade, Solanum nigrum; deadly nightshade, Atropa belladonna; Egyptian henbane, Hyoscyamus muticus; thorn apple, Datura innoxia; ashwagndha, Withania somnifera leaves and fruits of chili pepper, Capsicum frutescens were assessed on juvenile mortality and egg hatching of the root knot nematode, Meloidogyne javanica in vitro. The nematode mortalities were in the range of (54.33 to 100.0 %) in concentrations S/16, S/8 and S/4 compared to distilled water (1.33 %) and increased with the increase of the exposure time from 24 to 72 hrs. Deadly nightshade and chili pepper extracts were the most effective against second stage juveniles of nematode at concentration of S/4, followed by aqueous extracts of ashwagndha, thorn apple, black nightshade. Result showed that, the highest reduction in hatching inhibition percentage was recorded with concentration (S/4) of ashwagndha (97.63 %) followed by Egyptian henbane, deadly nightshade, black nightshade, thorn apple and chili pepper with inhibition percentages as (95.42, 94.60, 92.87, 79.61 and 67.97%) respectively. | ||
