The disease manifests in various ways, and signs can include brown rings and arcs on the surface of a potato, and discolored spots on the interior.
Tobacco Rattle Virus is common and potentially serious in a variety of herbaceous ornamentals including, but not limited to, astilbe, bleeding heart, coral bells, daffodil, epimedium, gladiolus, hyacinth, marigold, tulip and vinca.
The disease corky ringspot of potatoes was first reported in the United States in 1946, and was identified incorrectly as a novel virus until advances in genetics demonstrated it to be the result of TRV.
Common symptoms include mottling, chlorotic or necrotic local lesion, ringspots or line patterns, and systemic necrosis.
[6] At the beginning of the feeding cycle, the Stubby-Root Nematode punctures multiple individual cells by using its specialized stylet, an onchiostyle.
[9] Tobacco Rattle Virus can be managed through a variety of methods designed to make the environment unsuitable for transmission and viral propagation.
[12] While its use requires a permit from many state or local governments, the nematicide 1,3-dichloropropene may be employed against fields overrun by stubby root nematodes, a common vector of the virus.
[13] Soil fumigants generally fail to penetrate the 40 inches necessary to ensure nematode eradication, and carbamates such as aldicarb and oxamyl are recommended as a last resort.
Tobacco Rattle Virus is only found in nature in association with stubby root nematodes of genera Trichodorus and Paratrichodorus.
[15] While the Russet Burbank cultivar proves to be highly susceptible to Tobacco Rattle Virus corky ringspot, Merrimack and several old European varieties exhibit resistance.
Tobacco Rattle Virus infects hundreds of plant species and is found in every continent where crops are grown.
[17] In the United States, it has been reported in Florida, Michigan, Wisconsin, Minnesota, Colorado, Idaho, Oregon, Washington, and California.
[19] Corky ringspot from TRV has been known to cut yields from 6-55 percent in the Pacific Northwest, rendering those affected crops unmarketable.
