Abstract	The ability of several weed species to serve as hosts for tobacco rattle virus (TKV), the causal agent of corky ringspot disease of potato (CRS), and its nematode vector,Paratrichodorus allius, was investigated in greenhouse studies. ViruliferousP. allius multiplied on 24 out of 37 weed species tested, indicating they were suitable hosts of the vector. However, only 11 of these weeds were infected with TRV, as determined by ELISA. The nonhost status of a given weed species was not changed whether the viruliferous vector population originated from CRS problem fields in WA, OR, or ID. Several weeds served as hosts for the vector and virus including kochia, prickly lettuce, henbit, nightshade species (black, hairy, and cutleaf), common chickweed, and annual sowthistle. Virus-freeP. allius acquired TRV from the three nightshade species, volunteer potato grown from TRV-infected tubers, and prickly lettuce, and subsequently transmitted the virus to ‘Samsun NN’ tobacco indicator plants. Thus, some weeds may play a role in the epidemiology of CRS by perpetuating TRV and its vector in a problem field.La capacidad de diversas especies de malezas para servir como hospedante del virus rattle del tabaco (TRV), agente causal de la enfermedad de papa conocida como anillo corchoso (CRS) y de su vector, el nematodoParatrichodorus allius ha sido investigada en estudios de invernadero. ElP. allius se multiplicó en 24 de las 37 especies de malezas probadas, lo cual indica que son hospedantes apropiados del vector. Sin embargo, solamente 11 de estas malezas se infectaron con TRV de acuerdo a la determinación por el método ELISA. La condición de no hospedante de una especie dada de maleza no cambió aún en el caso de que la población del vector virulífero se hubiera originado en campos con problema de CRS de WA, OR, o ID. Diferentes malezas sirvieron como hospedante del vector y del virus incluyendo cochia-alfalfa, escarola, henbit, especies de hierba mora (negra, pilosa y de hoja cortada), hierba pajarera común y lechuguilla silvestre anual.P. allius libre de virus adquirió el TRV de las tres especies de hierba mora, de las plantas voluntarias de papa provenientes de tubérculos infectados y de la escarola y subsequentemente transmitió el virus a las plantas indicadoras de tabaco Sansum NN’. Es así como algunas malezas pueden jugar un rol en la epidemiología del CRS, perpetuando el TRV y su vector en un campo problema.
