"Potato yellow dwarf virus" (PYDV) is a plant virus of order "Mononegavirales", family "Rhabdoviridae" and genus "Nucleorhabdovirus". The virus was first identified in 1922 in the USA by Barrus and Chupp (1922) who reported it having an effect on the plant species "Solanum tuberosum". The virus is characterised for its various effects on the potato including stunted growth, dwarfing and apical yellowing. The virus also effects the tuber as it causes cracking and malformation. The virus is transmitted by the insect vector "Agallia constricta". The insect becomes infected upon feeding on an infected plant and then plays host for the virus infecting every plant it feed upon after this event.
