Prevalência de desoxinivalenol em trigo nas safras 2013/2014 e 2014/2015 no Rio Grande do Sul

Abstract

Due nutritional properties, wheat (Triticum aestivum L.) is one of the most consumed grains in the world and is present in both human and animal nutrition. The Brazilian southern region hasthe climatic condition of milder temperatures, accounts for 94.6% of the national production of wheat. Among the diseases that can affect wheat, there is the Fusarium wilt, which besides causing diseases in the plantation may develop, through its secondary metabolism, toxic substances called mycotoxins. The deoxynivalenol (DON) is a mycotoxin of the trichothecenes class, mainly produced by Fusarium graminearum and is among the most commonly found in small grain cereals, including wheat. Both globally and in Brazil there has been an increase in concern for mycotoxins, including DON. Therefore, knowing the extent of contamination can provide support for the various segments involved in the production, use and wheat imports and surveillance and research, always to ensure the final consumer a quality product.
