Production of deoxinivalenol by Fusarium graminearum and Fusarium culmorum isolated from wheat kernels in Serbia

Abstract

DON production by F. graminearum and F. culmorum isolated from wheat grains grown under different agroecological conditions in Serbia during two years were estimated. The incidence of F. graminearum differ considerably between localities, with frequency range from 3.13% to 25.80% and 1.61% to 21,90%, in 2005 and 2006, respectively. F. culmorum was isolated from one and tree localities in 2005 and 2006, respectively. Fourteen isolates of F. graminearum produced considerable amounts of DON, Up to 45.260 ppb, but the tree isolates of F. culmorum proved to be weak producers of this mycotoxin.
