All,
In one clump only, all of the plants are exhibiting slow but progressing leaf tip die-off. Reading thru Dr. Snazelle’s ‘Daffodil Diseases and Pests” the closest diagnosis I come up with is Narcissus tip necrosis virus.
Is my diagnosis on target, or are there other culprits?
Further, does this virus have a preferred host (tazettas, jonquils, etc) or is it equal opportunity? As this is the only patch afflicted, it does not seem to readily spread; the booklet doesn’t indicate if it spreads primarily by aphid or nematode…
Thanks!
