Ilarvirus is a genus of positive-strand RNA viruses in the family Bromoviridae.

[2] Plants serve as natural hosts.

[1][3] Viruses in the genus Ilarvirus are non-enveloped, with icosahedral and quasi-spherical geometries, and T=3 symmetry.

[1][3] Viral replication is cytoplasmic and lysogenic.

The virus exits the host cell by tubule-guided viral movement.
