Abstract
A survey was conducted to determine the distribution and occurrence of root-knot nematode, Meloidogyne spp. and other plant parasitic nematodes associated with Autumn pulses in Zone IIIA of Rajasthan. A total of 387 soil and root samples were collected from 25 different localities of zone IIIA in Rajasthan. Among them Meloidogyne spp. was found highest in 354 samples with 91.47% absolute frequency, 40.16 absolute density and 3.84 prominence value. Helicotylenchus spp., Pratylenchus spp., Hoplolaimus spp. etc., were also reported in surveyed localities. During the survey mung bean plants were found diseased with Cercospora leaf spot and anthracnose.
