First report of bean leafroll virus in chickpea, lentil, and dry pea in Montana.
In July 2018, bright yellowing, yellow to mosaic and light yellowing foliar symptoms were observed in chickpea, dry pea and lentil plots, respectively, in a Montana State University Research field at Bozeman and at a dry pea grower's field in Manhattan, Montana, USA. A total of 14 plants were collected from the 3 crop species, with 2 plants per cultivar, i.e. chickpea (Sierra and NDC160012), dry pea (Pea-Nwer18, NFW26 and Aragon) and lentil (ND Eagle and WA8649090). The Aragorn pea cultivar samples came from a grower's field in Manhattan. The rest of the samples were from the research field in Bozeman. The causal pathogen was isolated and identified as Bean leafroll virus (BLRV) based on molecular, serological and pathogenicity analyses. This is thought to be the first report of BLRV in dry pea, chickpea and lentil in Montana.
