In this article:
Grapevine yellow speckle disease was reported to be caused by an unknown graft-transmissible agent that induced leaf symptoms sometimes indistinguishable from those of vein banding disease.
This paper compares the leaf symptoms induced by an isolate of the vein banding strain of fanleaf virus with that of yellow speckle disease, both singly and combined, in different grapevine cultivars, and presents evidence that the yellow speckle agent is involved in the aetiology of vein banding disease.
