In nematicidal activitiy of sixty plant crude extracts from Albizzia spp. leaf, Nerium indicum leaf,Ricinus communis leaf,Ricinus communis leaf, Tithonia spp. leaf and Tithonia spp. flower extracted by ten different solvents were determined against the second juvenile(J2)of Meloidogyne spp..The result showed that the Albizzia spp. leaf ethanol, methanol, chloroform, ethyl acetate and carbon tetrachloride crude extracts, Lantana indica leaf methanol crude extract,Tithonia spp. flower ethanol, acetone, methanol and ethyl acetate crude extracts had stronger nematicidal activities against the J2. When concentration of these plant crude extracts were 2%(relating concentration of plant powder), J2 mortality rate were 100% in 24 hours. Several nematicidal components may exist in Albizzia spp. leaf and Tithonia spp. flower.
