Popis: Little cherry virus-2 (LChV-2) is a viral pathogen that is reaching epidemic levels in Washington State. This virus is insect vectored and has significant impacts on sweet cherry production. To aid growers in making informed management decisions, we sought to develop a diagnostic assay to better detect isolates of LChV-2 currently found in Washington, allowing more accurate estimations of disease occurrence. This study showed that there were two distinct genotypes of LChV-2 present in Washington State. This information was used to develop an up-to-date reverse transcription real-time quantitative PCR assay, which was then optimized, validated, and compared with four previously published assays of a panel of field samples. This comparison demonstrated that the newly developed assay provided greater sensitivity, accurately detecting
