Abstract: During August 2014 to July 2015, a total of 20 fallow locations at two widely separated zones viz., eastern and western districts of Tamil Nadu were sampled for quantitative analysis of plant parasitic nematode communities. A total of eight genera were identified from the fallow soil viz., Helicotylenchus incisus, Rotylenchulus reniformis, Hoplolaimus seinhorsti, Meloidogyne incognita, Tylenchorhynchus mashoodi, Pratylenchus penetrans and Radopholus similis have been recovered from the host free soils of eastern and western Tamil Nadu. Of these, four genera viz., Helicotylenchus incisus, Hoplolaimus seinhorsti, Meloidogyne incognita and Rotylenchulus reniformis were found to be predominant. These encountered plant parasitic nematodes were found to tolerate desiccation.
