In Romania, major economic losses in wheat crop are registered for some foliar diseases: fusarium head blight or scab (Fusarium graminearum), septoria/stagonospora leaf spot/blotch complex (Septoria tritici, Stagonospora nodorum), powdery mildew (Blumeria graminis) and, for several years, tan spot (Pyrenophora tritici-repentis). Foliar fungicides treatments are a major mean to prevent yield loses in wheat. Fungicides are the most effective when they are used as part of an integrated disease management strategy. Higher efficacy is expected when they are properly applied, in recommended dose and at optimal timing. The efficacy of fungicides treatments in controlling foliar fungal pathogens was evaluated in field trials conducted between 2010 and 2012, in three different locations (Fundulea - Călărși; Iazu - Ialomița; Slobozia - Giurgiu). Twelve fungicides (Artea, Alert, Amistar X-tra, Allegro, Capalo, Duett Ultra, Evolus, Falcon, Nativo, Opera Max, Osiris and Tango Super) applied in different schemes were tested. Fugicides efficacy was calculated based on foliar diseases incidence and severity compared to untreated control. Foliar treatments under all schemes significantly reduced the diseases severity. Differences in fungicides efficacy have been registered and were depending on wheat cultivar, location and implemented schemes.
