 ABSTRACT

Nematicidal efficacy of various medicinal viz., turmeric (Curcuma longa), marwatulsi (Origanum majorana), mentha(Mentha arvensis), aonla (Phyllanthus emblica) and jatropha  (Jatropha curcas)  was evaluated in vitro against root-knot nematode, Meloidogyne incognita. Ethanolic extracts of these plants were extracted and tested against root- knot nematode at different dilutions i.e. 1:5, 1:10, 1:20, 1:40 and 1:80. Ethanolic extracts of all plants showed nematicidal effect against M. incognita at varying degree. Percentage larval mortality and inhibition of egg hatching were directly proportional to the concentration of ethanolic extracts and exposure period to each extract. Ethanolic extracts of turmeric (C. longa) was found to be more effective amongst all other plant extracts in increasing mortality and inhibited the egg  hatching.

Key words: Essential oil, Meloidogyne incognita, nematicidal plants, mortality
