Dm. Trigostockli et al., COMPARISON OF THE DISTRIBUTION AND OCCURRENCE OF FUSARIUM-GRAMINEARUMAND DEOXYNIVALENOL IN HARD RED WINTER-WHEAT FOR 1993-1996, Cereal chemistry, 75(6), 1998, pp. 841-846
Hard red winter wheat samples collected from different locations in Ka
nsas from the 1993, 1994, 1995, and 1996 harvests were plated to deter
mine Fusarium graminearum infection and analyzed for deoxynivalenol by
thin-layer and gas chromatography. Rainfall, temperature, and cultiva
r were important factors affecting the severity of F. graminearum infe
ction as well as deosynivalenol production. The 1993 and 1995 growing
seasons and high percentages of samples infected with F. graminearum a
nd contaminated with deoxynivalenol. Averaged over the four years, cul
tivars 2163 and Karl had significantly higher levels of infection than
did TAM 107. These widely grown cultivars were used in comparison. No
rtheastern Kansas had the highest levels of F. graminearum infection a
nd deoxynivalenol contamination but also had the lowest acreage plante
d to hard red winter wheat.
