Zusammenfassung: | Fusarium head blight (FHB) of wheat is a very insidious disease caused by several fungal species prevalently belonging to the genus Fusarium. In Italy it has been consistently present since 1995. The most frequent species of Fusarium in wheat ears are F. graminearum and F. culmorum, but the composition of Fusarium population associated with this disease in the Emilia Romagna (northern Italy) has changed during the years. Our study has revealed the increased frequency of other Fusaria such as F. poae. Fusarium species involved are responsible for yield losses and decrease in grain quality, including the accumulation of mycotoxins detrimental to humans and animals. F. graminearum strains were examined using specific primers for chemotypes based on the production of the trichothecenes, deoxynivalenol (DON) (15ADON and 3ADON) and nivalenol (NIV). F. poae strains are also able to produce an extensive range of mycotoxins. In this work we found F. poae strains able to produce T-2 toxin, which is the most dangerous among all trichothecenes of A and B classes, and its derivative HT-2. The aim of the present work was to characterize Fusarium strains for their ability to produce different mycotoxins and to test their interaction with experimental trials, for controlling FHB and limiting mycotoxin contamination of grains. |
