'''''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.
