“…Additionally, fungicide treatments were performed by Rizolex ® and Signum ® application, one pre-transplant (3 g/m 2 ) and two post-transplant, in a range of 10 days (15 g/L), respectively. Three months after the transplant, an artificial inoculation was carried out in parcels A, D, and E, starting from fresh tissue material infected by an OYDV isolate, following previously described procedures [21]. For this study, three analytical time points were sampled, mirroring the 'Rossa di Tropea' onion bulb production steps: at harvesting time (t 0 ), i.e., at the complete development of plants and bulbs; an experimental check timepoint (t 1 ) during postharvest storage, i.e., 1 month after harvesting; and after storage (t 2 ), i.e., 3 months after harvesting, when the bulbs reach the marketable stage, corresponding to 2, 3, and 5 months post-inoculation, respectively.…”
