Broad bean wilt virus has only shown possible seed transmission in faba beans through artificial inoculation. It is not known to be common in nature. The virus is transmissible by sap inoculation and by several aphid species in the non-persistent.
Broad bean wilt virus has been reported in natural infections of 180 species of 41 plant families and thus has a very extensive natural host range. Main host families are: Apiaceae, Brassicaceae, Fabaceae, and Solanaceae.
