Root knot nematodes were extracted from five different plants (indian spinach, papaya, sweet gourd, okra and jute) collected from kurigram, gazipur, jessore and patuakhali districts of Bangladesh. Firstly, Meloidogyne spp. were identified morphologically mainly based on perineal pattern of adult female. Secondly, female were collected from plant roots and used directly in PCR for amplification of mitochondrial DNA (mtDNA) region between COII and lrRNA genes followed by hinfI digestion and sequencing. The root knot nematodes in indian spinach, jute and sweet gourd were identified as M. incognita whereas in okra and papaya were M. javanica.
