The effects of ethanol liquid extracts of Allium hookerrii (local name Maroinapakpi), Brucea javanica (local name heining), Clerodondrum indicum (local name Kuthap), Citrus latipes (local name Heiribop), and Elsholtizia Communis (local name Lomba) against infection caused by the Meloidogyne incognita in Vicia faba were determined. The seeds were soaked in 100 ppm stock solutions of the ethanol extracts of the above-mentioned medicinal plants for 24 h, dried in sunlight, and sowed in sterilized soil. After proper inoculation of juveniles of the M. incognita, the plants were allowed to grow. After 75 days of inoculation, the experimental plants were uprooted and observed. It was found that plants treated with the ethanol liquid from Brucea javanica showed much-improved growth rates and reduction in disease incidence when compared with the other treated plants. The ethanol extract of Allium hookerrii was found to be the least effective when compared with the extracts of other plants.
