Ringspots | Pacific Northwest Plant Disease Handbook. See also: Greenhouse Plants, Ornamental - Impatiens Necrotic Spot. Cause There are 1. Hydrangea ringspot virus (Hd. RSV) can be transmitted mechanically by leaf contact or by knives but not through seed or by aphids.
Suspected as cause of hydrangea running- out. Many cultivars are tolerant of the virus.
Hydrangea chlorotic mottle virus (Hd. CMV) can be transmitted mechanically or by the green peach aphid (Myzus persicae) but only infects H. Tomato ringspot virus (Tom. RSV) and Tobacco ringspot virus (Tob. RSV) are primarily vectored by nematodes. Tomato spotted wilt virus (TSWV) has also been recovered from hydrangea and is vectored by the western flower thrips.
Symptoms Hd. RSV - Leaves may show chlorotic to brown leaf spots or rings. Leaves become crinkled, rolled, and asymmetric. The number of florets per inflorescence also is lower in infected plants. Severe stunting and running- out also may occur.
Hd. CMV - Leaf mottling, blistering, and reddening and both chlorotic and ring spots were among the various symptoms found. Symptoms in the cultivar Endless Summer were more frequent during the spring but less so during the summer. Tob. RSV - stunting, some leaf distortion and leaf chlorosis with green blotches on leaves. Flower virescence (turning green) can also occur. TSWV - Ringspots are common but indistinguishable from those caused by Hd.
RSV. Cultural control. Soak knives in trisodium phosphate often when taking cuttings.
Use two knives so a worker can cut with one while the other soaks. When done with a batch, cultivar, etc. Buy clean stock, or isolate new stock from main plantings. Avoid nematode- vectored viruses by planting clean stock in containers in soilless media. Control weeds that may be reservoirs of virus and insect vectors. References Machado Caballero, J.
