Harmfulness of barley yellow striate mosaic virus and brome mosaic virus.
In Primor'e, Russian Far East, barley yellow striate mosaic cytorhabdovirus (BYSMV) is the most common virus infection of cereals, affecting wheat, barley and oats. Investigations conducted over many years showed that spring barley was the most susceptible to BYSMV, followed by wheat. Brome mosaic bromovirus (BMV) infection was less common. However, in field trials, BMV infected 47% of wheat and barley cultivars. BMV is known to infect 162 species of 7 families, with Bromus inermis, couchgrass [Agropyron] and other wild Poaceae species being reservoir hosts. Weed control and mowing of Poaceae near cereal fields are recommended for prevention of BMV.
