The reviews on production of banana during the recent years were not a satisfying one with respect to fourth position of Kerala in area of cultivation in India.Among so many factors for this declination,plant parasitic nematodes also found as a major negative factor.Thus the present study tried to prove this predict and conducted a survey in the unexplored rhizosphere region of an important crop banana(Nendran)in Palakkad taluk of Kerala,India during the post monsoon season of 2017.A total of twenty seven samples each were collected from banana rhizosphere soil and roots and processed for this study.The analysis revealed that the most abundant nematode population was Radopholus spp.and most frequently occurred genus was Meloidogyne spp.in the studied banana fields.The major diversity showing area were Elappully panchayath for rhizosphere soil samples and Kannadi panchayath for root samples.Different plant parasitic nematodes such as Aphelenchus spp.,Criconemoides spp.,Dory laimoides spp.,Helicotylenchus spp.,Hoplolaimus spp.,Meloidogyne sp p.,Pratylenchus spp.,Radopholus spp.,Rotylenchulus spp.,Tylenchoryn chus spp.and Tylenchus spp.were observed in both soil and root samples examined.
