Diversity of Plant-Parasitic Nematodes Associated with Assam Lemon

A comprehensive study was conducted to assess the diversity and community analysis of plant parasitic nematodes (PPN) in the rhizosphere soil of Assam lemon orchards across four districts in Assam. The study identified six predominant PPN genera: Tylenchulus semipenetrans, Helicotylenchus sp., Hoplolaimus sp., Tylenchorhynchus sp., Pratylenchus sp. and Rotylenchulus sp. The nematode community structure was analyzed using various ecological parameters. Among the identified PPN, T. semipenetrans and Helicotylenchus sp. were the most abundant (100%), followed by Hoplolaimus sp. (80%), Tylenchorhynchus sp. (60%) and Pratylenchus sp. (60%). This identification of PPN genera associated with Assam lemon orchards provides essential information for developing effective nematode management strategies aimed at reducing yield losses and enhancing food security.
