Identification on nematicidal compound in Glory lily (Gloriosa superba L.) and their different plant parts against, mortality of Meloidogyne incognita juveniles

N Ashokkumar, A Shanthi, M Sivakumar and K Rajamani

The present study was carried out in Department of Nematology, Tamil Nadu Agricultural University during March – June, 2016 to identify a nematicidal compound from different plant parts viz., rind, rhizomes, leaves, flowers and seeds of Gloriosa superba and the efficacy of nematicidal activity was tested against root knot nematode, Meloidogyne incognita in vitro also tested for its nematicidal property against M. incognita. The results of in vitro study revealed that, the methanol extract of rind, rhizomes, leaves, flowers and seeds of G. superba caused juvenile mortality of M. incognita. Its effect of causing mortality showed directly proportional to their concentrations and time of exposure. Among the different plant parts tested, rhizome extract was found effective followed by seeds caused juvenile mortality of M. incognita at 25, 50, 75 and 100 percent concentrations and different time of exposure. The rhizome extract significantly caused mortality of J2 of M. incognita even at 12h of exposure with 75 and 100 percent concentrations and total mortality was resulted after 24h of exposure at 100 percent concentrations and in all the concentrations after 48h of exposure. The rind was slightly less effective as compared to rhizome and seed extracts. The leaves and flower extracts were found less effective in caused juvenile mortality at different concentrations and time of exposure.
