| Summary: | Weeds and volunteer plants susceptible to Potato virus Y (PVY) infection in different seed potato
production sites were investigated in this study. Aphids occurring within these plants and identified as
Aphis fabae, A. gossypii, and Myzus persicae were studied for possible interaction occurring between
vectors and plant reservoirs of PVY. Out of 772 plants belonging to 12 different families (Solanaceae,
Amaranthaceae, Chenopodiaceae, Papaveraceae, Urticaceae, Convolvulaceae, Asteraceae,
Polygonaceae, Euphorbiaceae, Brassicaceae, Portulacaceae, and Compositae), 337 were found to be
infected by PVYN based on DAS-ELISA technique. Among these plants, Solanum elaeagnifolium,
Datura stramonium and Sonchus oleraceus were found to be infected with the strain PVYNTN. In
addition to these reported weeds, S. nigrum seems to be an important host for PVYN since this plant
hosts aphid vectors. This investigation provides basic information about weeds and volunteer plants
infected with PVYN and aphid vectors. Such finding will increase knowledge of the PVYN
epidemiology in potato fields and consequently the possible management of this viral disease. |
