The protein and non protein parts present in the leaves of Lippia nodiflora were separated and test their nematicidal activity against egg hatching and juvenile mortality of Meloidogyne incognita. The non protein part was found to inhibit the root knot nematode egg hatching under in vitro conditions. Leaf extraction was done with different solvent such as petroleum ether, chloroform methanol using soxhlet apparatus and the residue was discarded. | Isolation and identification of nematicidal principle in Lippia nodiflora against root knot Nematode Meloidogyne incognita
