Use of Eucalyptus sp., in the control of Meloidogyne javanica root knot nematode

Different parts of Eucalyptus sp., viz., leaves, stem, bark and fruit used as aqueous and ethanol extracts showed nematicidal effect against Meloidogyne javanica root knot nematode, reduced hatching of eggs, increased mortality of juveniles with an increase in exposure of time and showed efficiency in the control of Meloidogyne javanica root knot nematode on mung bean and chick-pea plants. Significant increase in shoot length, shoot weight, root length and root weight was observed where soil was amended with leaves, stem, bark and fruit of Eucalyptus sp., used @ 0.1, 1 and 5% w/w. Number of knots was also significantly reduced. All plant parts of Eucalyptus spp., were more effective @ 5% w/w.
