Fusarium is a major disease in most wheat growing areas around the world, including Romania. Five species of the genus Fusarium can cause this to wheat, Gibberella zeae Schwain (Petch.) (with anamorphous Fusarium graminearum Schwabe) is the predominant pathogen in many parts of the world. This disease not only causes crop losses, but also contamination of wheat with fusariotoxine (especially deoxynivalenol, DON) which, due to cytotoxic and immunosuppressive properties, are harmful to humans and animals. DON content was analyzed in samples of wheatharvest 2012 and 2013, taken from field plots (mixture from 5 repetition for each variant) The maximum Fusariotoxine limit allowable for cereals, regulated by Commission Regulation (EC) No. 1126/2007 of 28 September 2007 (amending Regulation (EC) No. 1881/2006), is 1.25 mg / kg (ppm). The protection of crops against mycotoxin contamination using fungicides is not always productive; the application of bio stimulant seems to be promising in this respect. At some specific stages of wheat (Triticum aestivum L.) growth, commercially available organic growth stimulants (biostimulants) were tested from 2012 and 2013 in experimental field. The purpose of our work was to evaluate the effect ofbio stimulants treatment on mycotoxin content in grain harvest. The application of bio stimulants in recommended dosages, depending of the year (connected with climatic conditions) and variant, has been found that could reduce the content of DON till 0.5405 and 0.781 mg/kg (ppm), in 2012 and 2013 respectively.
