Epidemiology of tomato spotted wilt tospovirus in Liguria (IT)

In Liguria (IT), the influence of wild plants on the occurrence of tomato spotted wilt tospovirus (potential EPPO A2 quarantine pest) were investigated. During the summer of 1992, 1446 samples of weeds and wild plants from 22 botanical families were collected and investigated for the presence of tomato spotted wilt tospovirus and impatiens necrotic spot tospovirus (potential EPPO A2 quarantine pest). Only 14 samples proved to be TSWV positive and none showed any infection by impatiens necrotic spot tospovirus. The authors assumed that the very small amount of infected weeds and wild plants indicate that they do not play a major role in the epidemiology of tomato spotted wilt tospovirus.
