Community analysis of plant parasitic nematodes in turmeric (Curcuma longa L.)

Abstract

The present investigation was conducted on Aug to Dec’2014 to study the community structure of phytonematodes associated with turmeric under conventional and drip irrigation methods. Species were identified on the basis of perineal patterns of females. The predominant nematode species were Meloidogyne incognita, Pratylenchus delattrei, Radopholus similis, Longidorus elongatus, Xiphinema elongatum, Hoplolaimus seinhorstii, Helicotylenchus multicinctus, Tylenchorhynchus martini and Rotylenchulus reniformis were encountered from the rhizosphere soil of turmeric grown under both system of irrigations. This is the first record of various species of phytonematodes associated with turmeric crops cultivated under conventional and drip irrigation system.
