Common Name

Ramu stunt disease

Scientific Name

Sugarcane Ramu stunt disease. Initially, the cause of the disease was thought to be a virus; later, phytoplasmas were detected (related to sugarcane white leaf phytoplasmas) in diseased plants and also in planthoppers (Eumetopina flavipes), which may spread the disease. More recently, a virus has again been suggested. Advanced RNA sequencing techniques may have found a virus belonging to the Tenuivirus group.
