Rhubarb mosaic virus

Arabis mosaic virus has a wide range of hosts including cherry, peach, plum, raspberry, rose, strawberry, celery, lettuces and grape. In total 93 species of plants have been identified as susceptible.[1] The primary method of spread is through movement of infected propagation material.[2]

Symptoms[edit | edit source]

The most common symptoms induced by ArMV are leaf mottling and flecking, stunting and several forms of deformation including enations. The symptoms vary depending on the host plant but also on virus isolate, cultivar, season and year. Many infections with ArMV are latent and the plants do not show symptoms.[1]

Grape[edit | edit source]

Infected plants may have shortened internodes and exhibit vine decline symptoms. The symptoms are similar to those of Grapevine fanleaf virus (GFLV) and mixed infections of ArMV and GFLV are common. Infections are often symptomless and expression varies based on type of rootstock, variety, and environmental conditions. Yield losses of up to 50 percent have been attributed to ArMV.[2]

In areas where infective nematode-vector populations are present, replanting of virus-free material without additional measures will be ineffective: soil fumigation and/or fallow for at least one year seem to be good additional procedures for the limitation of disease spread.[1]

Control[edit | edit source]

Growers should plant certified, disease-free plants. Pruning tools should be disinfected with a bleach solution (1 part household bleach, 9 parts water) between cuts. Infected plants should be removed and discarded.[2]
