Abstract: | A number of solanaceous and composite plant species were tested as hosts for the causal agents of pepper yellow vein (PYVA) and lettuce big vein (LBVA), transmitted by a pepper and a lettuce isolate ofOlpidium brassicae, respectively. The agents had the following artificial hosts in common:Lycopersicon esculentum, Solanum melongena, Physalis floridana, Nicandra physaloides, Lactuca sativa, Sonchus oleraceus andL. virosa. Capsicum annuum, S. villosum, S. nigrum, Crepis vesicaria andSenecio vulgaris were infected by PYVA, but not by LBVA.Cichorium endivia andTaraxacum officinalis were not infected by any of the two agents.N. physaloides, although not colonized by the pepper isolate ofOlpidium, still became infected by PYVA. |
