Abstract

Population dynamics of some plant parasitic nematodes in the rhizosphere of tuberose and marigold crops were studied. Population density was recorded at monthly interval from May, 2016 to February, 2017 in tuberose and from June, 2016 to November, 2016 in marigold. High population density (>200 nematodes / 200 cc soil) of root-knot nematode, Meloidogyne incognita and reniform nematode, Rotylenchulus spp. was recorded in tuberose from July, 2016 to November, 2016. Population dynamics of other nematodes such as Pratylenchus spp. and ectoparasitic nematodes were also recorded in the rhizosphere of tuberose crop. In marigold, population density of plant parasitic nematodes such as Pratylenchus spp., Hoplolaimus spp., Helicotylenchus spp., Tylenchorhynchus spp. and Longidorus spp. Were decreased when marigold cultivars Pusa Narangi Gainda and Pusa Basanti Gainda were grown in sequence on the same field. However, these marigold cultivars did not influence the population density of Xiphinema spp.
