Toxicity and occurrence of Fusarium species and mycotoxins in late
harvested and overwintered grain from Norway, 1993.
Samples
of grain harvested in October/November of 1993 or in the spring of 1994 from
fields in Norway with overwintered grain were examined for the presence of
Fusarium species and mycotoxins.
F. culmorum was found more in the samples from October/November while F.
avenaceum was isolated more in the grain harvested in the spring. Only small amounts of F.
sporotrichioides were present in the grain harvested in the autumn, and none
was found in the overwintered grain.
The deoxynivalenol content was significantly higher in the grain
harvested in autumn than in the overwintered grain. Although very small amounts of toxins were detected in the
overwintered grain, it was more cytotoxic than the grain harvested in
October/November. A significant
correlation between the cytotoxicity and the amount of F. avenaceum in the
samples was found.
