Improved detection of Blueberry Scorch virus, a major pathogen in BC blueberry farms

Disease and death of blueberry plants caused by Blueberry Scorch Virus (BlScV) is a major problem in Blueberry farms of British Columbia, a key sector of the local agricultural economy. Correct diagnosis is instrumental to separate from non-lethal Shock Virus as BlScV-infected plants should be removed to reduced spread to other plants. In recent years, however, a substantial portion of diseased plants test negative for both viruses using the preferred and affordable ELISA method. We have compared detection methods and found that the virus is not detected by the preferred and affordable method of detection. Here we propose to test if the discrepancies are due to new BlScV variants in BC and/or an issue with the sensitivity of current preferred diagnostic method. Depending on the results, we will (a) develop new detection assay adapted to local BlScV variants or (b) test new methodology to improve sensitivity of current method.
