Abstract: Fusarium head blight of wheat is a disease of increasing importance in Italy both for yield losses and health risk since the causal fungal species can produce mycotoxins that can occur in meals and cereal based food. This disease, reported for soft wheat, has also been recorded on durum wheat, especially in central-northern localities of Italy, where the climatic conditions are conducive for fusariosis. Among the species involved, are Fusarium avenaceum, F. culmorum, F. graminearum, and F. poae. Microdochium nivale is also often associated with this disease. The results of the epidemiological and toxigenic surveys carried out in two years on fungal species occurring in experimental fields of durum wheat in Marche, Lazio, Puglia, Basilicata, and Sicilia, and soft wheat in Emilia-Romagna and Umbria, indicated that the mycotoxin profile in grain was related to the particular Fusarium species present. Differences in the species detected at each location indicates that each species have specific ecological requirements to initiate disease and produce toxins. Mycological observations using specific DNA molecular markers and competitive PCR on ear samples, collected at random at three growth plant stages (blossoming, milk and full kernel maturations) were related together with meteorological data recorded. The results are being used to develop a preliminary previsional model for the disease and mycotoxin risk assessment.
