A Two-Year Field Experiment for the Integrated Management of Bread and Durum Wheat Fungal Diseases and of Deoxynivalenol Accumulation in the Grain in Central Italy

A two-year (2018/19 and 2019/20) field experiment was carried out to evaluate the efficacy of recently developed fungicide combinations (with different modes action) towards fungal diseases on seven bread eight durum wheat varieties. The trial performed at FIELDLAB experimental station University Perugia (Italy). were assessed under natural pressure except for Fusarium head blight (FHB) which artificial inoculation with a culmorum deoxynivalenol (DON)-producing strain full flowering stage (BBCH 65). Fungicides sprayed fully extended flag leaf 39) 65) stages. incidence visually evaluated other parameters [grains production (t/ha), protein content (%), test weight (kg/hL), DON accumulation in grain (μg/kg)] also determined. In two years, characterized by climatic conditions, treatments showed controlling observed (Septoria tritici blotch FHB) as well reducing contamination. No significant differences found between treatments. results highlight that, present scenario commercially available varieties, timely application most common fungicides plays crucial role FHB management presence conditions that are favorable disease. impact these an integrated disease perspective is discussed.
