The current study was carried out to evaluate the nematicidal potential of different extracts of seeds, ripe fruit without seeds, unripe green fruit and powdered fruit of Citrullus colocynthis against second stage juveniles of root-knot nematodes, Meloidogyne incognita. The activities of extracts were examined in vitro and was compared with the positive control (Furadan). This study gave an overview of nematicidal potential of C. colocynthis and showed great activity up to 99% mortality of juveniles of M. incognita in some extracts. Ethyl acetate (EA) and Methanolic extract (Me) of Citrulllus seed (CS) have shown 99.33 and 98.66% mortality, respectively, 92.66% mortality was obtained from Me extracts of green fruit (CG) whereas Petroleum ether (PE) and (EA) extracts of powdered fruits were found 98.00 and 94.66% effective against M. incognita after 72 hrs of exposure. This study concludes the use of this fruit as a potential source of bio-pesticide.
