passiflora, walter's viburnum...mottled leaves with no indicaion of any insects. Someone suggested it might be a virus and I was just wondering what kind of treatment if any there was for such a thing.

Dale, to make your problem a little more understood..a virus is generally transmitted by a vector(insect), most of the time by mechanical inoculation(grafting, etc)......happens in certain roses also. Many plant Families are susceptible to viruses.... What I suggest is to take a leaf from these plants to your nearest nursery or garden center and have them diagnose!!! other than that, your Plant Sciences outlet(such as Agriculture Dep't....they certainly should identify the problem....try not to diagnose this yourself! good luck.....Elaine

Dale, more bad news: if it is a virus causing the leaf problems, there is only one treatment: throw it away. Don't even compost it unless you maintain a very hot compost pile (160 F). There is no cure for plant viruses :( And due to the transmissibility Elaine mentioned, it is possible or likely to spread to other plants in the area. But definitely get a diagnosis first if this is an important plant.

Typically viruses cause mottling or streaking of leaves; fewer flower buds with reduced fruiting. That is the economic reason many people destroy virus-laden plants, especially commercial food growers.
