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

Abstract: Studies were carried out 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 eggs. The results of in vitro study revealed that, the methanol extract of rind, rhizomes, leaves, flowers and seeds of G. superba inhibited egg hatching of M. incognita eggs. Its effect on inhibition of hatching showed directly proportional to their concentrations and time of exposure. Among the different plant parts tested, rhizome extract was found effective followed by seeds in inhibition of egg hatching of M. incognita at 25, 50, 75 and 100 per cent concentrations and different time of exposure. Total inhibition was noticed at higher concentrations of 75 and 100 per cent after 48h of exposure and at 72h total inhibition was noticed in all the concentrations. The rind was slightly less effective as compared to rhizome and seed extracts. The per cent inhibition in hatching was less than 50 per cent after 12h and its efficacy increased after 48 and 72h of exposure. Total inhibition in hatching was not noticed even after 72h of exposure in higher concentrations. The leaves and flower extracts were found less effective in inhibition of hatching at different concentrations and time of exposure.
