Time point of virus yellows infection is crucial for yield losses in sugar beet, and co‐infection with beet mosaic virus is negligible under field conditions

open access: yesPlant Pathology, Volume 73, Issue 8, Page 2056-2070, October 2024.
Early virus yellows infections cause significant yield loss in sugar beet while late infections do not. Beet mosaic virus alone does not cause significant yield losses; only in co‐infection with beet mild yellowing virus (BMYV), losses exceed those from single BMYV infection.
