Surveys for the detection of Stewart's wilt in Friuli Venezia Giulia (Italy) (2017–2018) in maize fields other than for the production of seed for sowing (grain or silage). Some fields were repeatedly sampled; therefore, positive samples do not necessarily correspond to different fields. In several cases, symptomatic plants were found close to each other, e.g. adjacent plants on the same row, or plants in different rows but very close to each other
