Studies on the Occurrence, Distribution and Community Analysis of Plant Parasitic Nematodes Associated with Maize, Tomato, Mulberry, Banana and Sugarcane in Erode District of Tamil Nadu

The pathogenic ability of plant parasitic nematodes in a specified locality is determined through community analysis. This investigation involves the analysis of plant parasitic nematode populations and their associated parameters in the rhizosphere of Maize, Tomato, Mulberry, Banana and Sugarcane grown in Erode district of Tamil Nadu. There were several nematode genera identified in the plant rhizosphere, such as Pratylenchus spp., Tylenchorhynchus spp., Meloidogyne spp., Helicotylenchus spp., Helicotylenchus spp., Hoplolaimus spp., Criconemoides spp., Xiphinema spp. and Longidorus spp. Community analysis of nematodes associated with the aforementioned crops varied in terms of their frequency and density. In Maize, Longidorus spp. was reported to be the predominant genus with the absolute frequency value of 100% and the prominence value of 2.87. Meloidogyne spp. was the most economical nematode in tomatoes, with an absolute frequency of 72.72% and prominence value of 6.29. Xiphinema spp. was the more frequently occurring nematode in Mulberry, with the absolute frequency of 100% and prominence value of 21.06. In Sugarcane, Hoplolaimus spp., which had an absolute frequency of 90.90%, was the most prominent nematodes in sugarcane. In Banana, Pratylenchus spp. had the highest prominence value and density (absolute and relative).
