Babuvirus is a genus of viruses, in the family Nanoviridae.[1] Musa species serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: stunting, severe necrosis and early plant death. BBTV induces banana bunchy top disease (BBTD).[1][2][3]
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:[3][4]
- Babuvirus abacae, Abaca bunchy top virus
- Babuvirus cardamomi, Cardamom bushy dwarf virus
- Babuvirus musae, Banana bunchy top virus
