ABSTRACT

Experiments were conducted in vitro to assess the nematotoxic effect of crude alcohol soluble fractions of Pongamia pinnata, Lantana camara, Euphorbia pulcherrima, Thevetia peruviana, Martynia annua and Opuntia on root-knot nematode Meloidogyne incognita. Plant extracts were assayed for ovicidal and larvicidal effect. Leaf extracts of Pongamia pinnata, Lantana camara, and Euphorbia pulcherrima were found to be most effective where as leaf extract of Thevetia peruviana and Martynia annua as well as cladode extract of Opuntia did not show appreciable results.

Keywords : Alcoholic fractions, Ovicidal, Larvicidal, Nematotoxic, and Meloidogyne incognita.
