Fusarium species, chemotype characterisation and trichothecene contamination of durum and soft wheat in an area of central Italy.

摘要: BACKGROUND Fusarium head blight (FHB) of wheat is an important disease causing yield losses and mycotoxin contamination. The aim the work was to detect characterise trichothecene producing Fusarium species in durum soft cultivated area central Italy 2009 2010 determine contamination by LC-MS/MS grain. RESULTS F. graminearum s. str. most frequent species. In 2009, occurrence F. avenaceum poae higher than 2010. Among strains, 15-acetyl deoxynivalenol (15-ADON) chemotype could be found more frequently, followed nivalenol (NIV) 3-ADON chemotypes, while all culmorum isolates belonged chemotype. All strains were NIV chemotypes. vitro production confirmed molecular characterisation. Durum characterised a average DON with respect wheat, always detected at appreciable levels type-A trichothecenes mostly samples 6% exceeding level recently recommended European Union. CONCLUSION Climatic conditions predominant factors influencing mycotoxigenic composition contaminations. However, occur irrespective climatic conditions, suggesting that it may often represent under-estimated risk further investigated. © 2014 Society Chemical Industry
