Document title. Nematicidal activity of serpentine against Meloidigyne incognita ...Not Availabl

Not AvailableNematicidal activity of essential oil of Pelargonium graveolens L.(cv. Algerian) and
its major constituents namely citronellol, geraniol and linalool was determined against the
root-knot nematode Meloidogyne incognita. Geraniol was found to be the most effective
constituent which was followed by citronellol and linaloolNot Availabl

Not AvailableAmong the various solvent extracts of the bulbs and seeds of onion assayed far in vitro nematicidal activity against root-knot nematode, Meloidogyne incognita, hot methanol extract of defatted seeds exhibited significant activity. The active extract contained a compound which fluoresced in ultra violet light; it coloured pink when sprayed with diazotized sulphanilic acid followed by sodium hydroxide on a TLC plate. Free amino acids viz. leucine (isoleucine), aspartic acid, methionine and threonine each exhibited nematicidal activity, but to a much lesser extent than the extract itself.Not Availabl
