Parkia javanica, Zanthoxylum acanthopodium, Jatropha curcas, Vitex negundo and Adatoda vasica were tested as seed soaking against rice root knot nematode. The seeds were soaked in 100ppm concentration for 24 hours. The plants treated with essential oil extract of Jatropha curcas showed improvement in plant growth and reduction in diseases incidence when compared with other treated plants. Essential oil extracts of Zanthoxylum acanthopodium was found to be least effective among five tested plants.
