Molecular detection of pest and pathogens relies on rapid and dependable methods for their identification as well as an assessment of their abundance. This study describes the development and evaluation of a diagnostic method for detection of Pratylenchus crenatus, P. penetrans and P. neglectus, based on a hydrolysis probe qPCR assay. Primer/probe sets were designed targeting the ITS-1 rDNA. In order to assess the specificity, primer/probe sets were tested with samples of non-target Pratylenchus species and Radopholus similis. Experiments using dilutions of purified plasmid standards tested the sensitivity of the hydrolysis assay against detection of DNA extracted from individual nematodes. Target DNA was detected in soil samples collected from potato fields and this indicated that P. crenatus, P. neglectus and P. penetrans are widely distributed in Scotland, frequently co-existing in mixed populations, with P. crenatus more prevalent than either P. neglectus or P. penetrans.
