The burrowing nematode, Radopholus similis, is an obligate migratory endoparasite. Currently detection of this nematode is carried out mostly by physically extracting them from soil and then observing under a light microscope. To identify this nematode, a thorough knowledge about their morphological features is quite indispensable. Developing a DNA based detection technique makes it more convenient and accurate in detection. Though PCR based methods have been reported by earlier workers, developing a Real-Time PCR based method will enable estimating their population in field samples. In this study, Real-Time PCR primers were designed using the DNA sequences from the ITS region of R. similis. It can detect R. similis up to the limit of 100 fg μL-1 DNA. The real time PCR based detection serves as an efficient tool for the detection and estimation of this nematode from soil samples.
