'Narcissus white streak virus'' (NWSV) is a plant pathogen of the family Potyviridae which infects plants of the genus ''Narcissus'', and is transmitted by aphids.〔 It is among the commonest and most serious of the viral infections that infect narcissi, but appears to be confined to ''N. tazetta''. == Description == This virus causes narrow greenish purple streaks that turn white to yellow, on the leaves and flower stalk after flowering, and premature senescence, which reduces bulb size and yields.〔("Narcissus (''Narcissus'' spp.)".
