Essential oil products of some medicinal plants as bio control agents against egg hatching and larval mortality of Meloidogyne incognita

Abstract

Petroleum ether extracts of six different medicinal plants Adhatoda vesica, Plumeria rubra, Mussenda globra, Mellia azedarach, Xylosoma longifolia and Andrographis panniculata were tested against egg and second stage juveniles of Meloidogyne incognita in terms of percentage of mortality and rate of inhibitory action in egg hatching. Among these six petroleum ether extracts leaves extracts of Andrographis panniulata was found most effective in both larval mortality and egg hatching followed by Mellia azedarach petroleum extracts. Although their effect in egg and larvae of M. incognita differ but these six petroleum ether extracts were found effective and can be used for the control of root knot nematode M. incognita
