In commercial highbush blueberry crops in Michigan, USA, BLMoV causes virtually 100% crop loss within 4-5 years after infection. Infected blueberry cv. Jersey does not usually die, but growers remove diseased bushes when symptoms are evident. BLMoV had infection levels varying from 16.3 to 70% in studied vineyards (V. vinifera) of the Republic of Korea, but caused no major damage (Kwak et al., 2016).
Prevention is the best means of control. Only virus-tested plant material from an approved certification scheme should be planted (EPPO, 1998). If the disease is already present in a planted area, all infected plants should be identified by ELISA or RT-PCR tests and destroyed. If plants are only cut back to ground level and allowed to regrow, blossoms will for which will bear infected pollen and be an inoculum source for healthy blueberry plants. Beehives should be placed as far away as possible from any diseased wild or cultivated bushes.
BLMoV is extremely damaging to Vaccinium spp. (Martin & Tzanetakis, 2018) which are currently crops of increasing importance in the EPPO region. The BLMoV isolates/strains reported from the Republic of Korea (Kwak et al., 2016) and New York State (US) (Uyemoto et al., 1977) attack Vitis spp., but their economic impact on grapevine cultivation remains to be further studied. The risk BLMoV could present for grapevine seems to be limited, and in principle could be covered by certification of planting material according to a scheme such as the one.
