COLLECTION AND POPULATION FREQUENCY OF PHYTO-PARASITIC NEMATODES ASSOCIATED WITH BRINJAL (Solanum melongena) IN NORTH UTTAR PRADESH REGIONS: A FIELD STUDY

A survey was conducted to determine the types, frequency and population of plant parasitic nematodes associated with the soils and roots of Brinjal (Solanum melongena) in various Agra regions (e.g. Etmadpur, Sewla, Kheragarh, Samshabad) using random sampling for soil and root and using pie pan modification of Baerman funnel methods for plant parasitic nematode extraction. Plant-parasitic nematodes recovered included Meloidogyne spp., Pratylenchus spp., Radopholus spp., Trichodorus spp., Rotylenchus spp., Helicotylenchus spp. and Rotylenchulus spp. Seven genera of plant parasitic nematodes were encountered in Agra; while six genera in Etah and Mathura of U.P. respectively.
