Interpretive Summary: Since both wheat and corn are hosts of tobacco rattle virus (TRV) and may serve as a source of virus for transmission to subsequent potato crops grown in the same soil, these crops play an important role in the maintenance and survival of the virus between potato crops. Where TRV has infested soils, growers should consider substituting TRV resistant crops, such as Alfalfa and mint, for wheat and corn in the crop rotation with potatoes.

Technical Abstract: Corn and wheat are important rotation crops with potato in the Northwest. The roots of both are infected by tobacco rattle virus(TRV), the causal agent of corky ringspot disease of potato. Our work demonstrated that the vector of TRV may acquire TRV from infected roots of both wheat and corn and transmit the virus to potatoes in subsequent crops.
