This study was designed to evaluate the nematicidal effects of Impatiens bicolor Royle extracted with various solvent systems to explore its potential use in agriculture as pesticide. Extracts of I. bicolor Royle obtained from n-hexane (A), dichloromethane (B), ethyl acetate (C), n-butanol (D), aqueous (E) fractions as well as crude (F) were tested in vitro for their nematicidal activities against Cephalobus litoralis, Helicotylenchus indicus, Meloidogyne javanica and Meloidogyne incognita. All fractions as well as crude extract showed toxicity in a dose and time dependent manner. Ethyl acetate fraction however showed more potent nematicidal effects.


Key words: Impatiens bicolor Royle, nemacitidal, pesticide.
