Abstract:
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
