Abstract:
A roving survey was conducted in Kamrup, Morigaon and Jorhat district of Assam during the year 2018-20 in order to determine the most important plant parasitic nematodes species associated with tuberose. The analysis of soil and root revealed the presence of seven different genera of plant parasitic nematodes viz., Meloidogyne incognita, Helicotylenchus spp., Hoplolaimus spp., Tylenchorhynchus spp., Pratylenchus spp., Rotylenchulus reniformis and criconematids. The present investigation revealed that M. incognita is one of the serious limiting factors in commercial cultivation of tuberose in Assam.
