Abstract:
The aim of the present study was to evaluate nematicidal, herbicidal and insecticidal activity of rhizome chloroform oleoresin of Hedychium coronarium J. Koenig. The GC-MS analysis led to identification of fifteen constituents comprising of 87.9% of total oleoresin composition. The major component found to be was Coronarin E (20.1%). The oleoresin exhibited the significant nematicidal activity against the Meloidogyne incognita nematode and effective herbicidal activity against the R. raphanistrum subsp. sativus seeds on the basis of three distinct parameters that was percent inhibition of seed germination, inhibition of root length, and inhibition of shoot length respectively. Oleoresin also showed potent insecticidal activity by using no choice leaf dip method in a sequentially dose and time dependent manner against Spodoptera litura.
