Abstract
From the literature it appears that lilac ringspot is the most common virus disease of lilac (Syringa vulgaris). Symptoms are leaf deformations, rings and line patterns which vary greatly in size and shape.
Several authors report on viruses isolated from lilac, such as elm mottle, tomato black ring, arabis mosaic and lilac mottle virus, but none of these viruses have yet been proven to be the cause of lilac ringspot.
In experiments at Wageningen between 1972 and 1976 arabis mosaic, lilac ring mottle and tobacco rattle viruses were isolated from lilac.
The three viruses could be transmitted to lilac seedlings by manual inoculation with sap of infected herbaceous plants, and caused symptoms that show some similarity to lilac ringspot.
From several lilac bushes an unknown virus with long flexuous rods (code name St. 30) was isolated.
However, from field observations on a number of source plants used in many sap inoculation experiments it is concluded that none of the viruses mentioned so far is the main cause of lilac ringspot.
