Luteovirus pavhordei

Assigned virus:
barley yellow dwarf virus-PAV (BYDVPAV)

The barley yellow dwarf virus-PAV is part of the Barley yellow dwarf virus complex. It is widely distributed and is transmitted mainly by the cereal aphids Rhopalosiphum padi and Sitobion avenae, as indicated by "PAV". Like the other viruses from the BYDVs, the symptoms are characterised by yellowing and dwarfing. Also the flag leaf turns yellow. The main host plants are wheat, barley and oats. Other cereals can also become infected and various grasses have been reported as hosts.
