<jats:title>ABSTRACT</jats:title>
<jats:p>
We evaluated
<jats:italic>Fusarium</jats:italic>
contamination and the levels of hexadepsipeptide mycotoxins in 13 wheat samples affected by head blight in Finland.
<jats:italic>Fusarium avenaceum</jats:italic>
was the dominant species (91%) isolated from all samples, but isolates of
<jats:italic>F. culmorum</jats:italic>
(4%),
<jats:italic>F. tricinctum</jats:italic>
(3%), and
<jats:italic>F. poae</jats:italic>
(2%) also were recovered. Beauvericin (0.64 to 3.5 μg/g) was detected in all 13 samples. Enniatin B (trace to 4.8 μg/g) was detected in 12 samples, enniatin B
<jats:sub>1</jats:sub>
(trace to 1.9 μg/g) was detected in 8 samples, and enniatin A
<jats:sub>1</jats:sub>
(trace to 6.9 μg/g) was detected in 10 samples. Ten of 13 strains of
<jats:italic>F. avenaceum</jats:italic>
and 2 strains of
<jats:italic>F. poae</jats:italic>
and
<jats:italic>F. tricinctum</jats:italic>
produced beauvericin in culture on rice (trace to 70, 9.4, and 33 μg/g, respectively). All strains also produced enniatins (trace to 2,700 μg/g). This is the first report on the natural cooccurence of beauvericin and enniatins in wheat infected predominantly by
<jats:italic>F. avenaceum</jats:italic>
.
