Correlation of deoxynivalenol and zearalenone production by Fusarium species originating from wheat and maize grain

A total of 39 Fusarium graminearum, F. sporotrichioides, F. semitectum and F. equiseti\udisolates, originating from wheat and maize samples collected at 10 locations in Serbia, were\udanalyzed by ELISA method for their potential of deoxynivalenol (DON) and zearalenone\ud(ZEA) production under optimal laboratory conditions. Fusarium graminearum isolates with\udthe highest intraspecies variability were the best producers of both deoxynivalenol and\udzearalenone. In contrast, F. equiseti isolates were the weakest producers of these two toxins.\udConsidering the plant origin of the isolates, wheat-originating F. sporotrichioides isolates\udwere better deoxynivalenol producers, while the maize-originating isolates produced more\udzearalenone. There was no clear difference in ZEA production between wheat- and maizeoriginating\udisolates of F. graminearum, while higher average DON concentrations were\udproduced by F. graminearum wheat-originating isolates.\udNegative correlation was detected between the production of deoxynivalenol and\udzearalenone by various Fusarium spp
