Description
BBWV was first isolated from broad beans (Vicia faba) in Australia in 1947, and is transmitted by aphids. Despite its name, BBWV has a wide range of hosts including both monocotyledons and dicotyledons, but mainly the latter. By 1991 177 species in 39 families had been reported as being infected with BBWV. These include perennial bulbous ornamentals such as Narcissus tazetta.
