Abstract

Aim: Mungbean (Vigna radiata (L.) R. Wilczek) is one of the important pulse crops grown in India. Considering the economic importance of nematodes as disease causing organism of mungbean the present investigation was carried out to know the distribution of plant parasitic nematodes in mungbean crops in Jaipur district of Rajasthan. Methodology: A total 139 soil samples were collected from mungbean fields of 12                          different localities in Jaipur district. The samples were processed using Cobb's                                  sieving and decanting technique followed by Baermann's funnel technique and nematode population was counted in suspension and identified on the basis of their morphological       characters. Results: The samples were infected with mainly four genera of plant parasitic nematodes i.e., Meloidogyne spp., Helicotylenchus spp., Pratylenchus spp. and Tylenchorhynchus spp. etc. Out of 139 soil samples, 120 samples showed the presence of Meloidogyne javanica with 86.33 % occurrence, 18.82 % absolute density, 83.81 % relative density and 15.85 % prominence value and found most predominant in different surveyed localities in Jaipur district.
