In Romania as well as worldwide, Fusarium head blight
(FHB), also known as scab, is a devastating disease of small
grains causing serious yield losses and low grain quality.
The disease commonly occurs in wheat, barley, rye and less
in oats. The main causal agents of FHB in Europe are
Fusarium graminearum and Fusarium culmorum, but
Fusarium proliferatum or Fusarium verticiliodes could be
also present. Although FHB may cause wheat yield losses,
the interest in FHB is primarily fuelled by the ability of
Fusarium species to produce mycotoxins.
The aim of this work was the Fusarium species identification
based on molecular anaylisis as well as mycotoxin
quantification, correlated with the climatic conditions.
Among the wheat samples collected from Arad and Timis
counties, 5 were totally free of Fusarium infection,
2 samples were infected only with Fusarium graminearum, 5
samples were infected with Fusarium culmorum, 5 samples
were infected with both species, Fusarium graminearum and
Fusarium culmorum. Taking in account the chemotype, 4
samples were infected with DON chemotype, 1 sample was
infected with NIV chemotype and 7 samples contained both
DON and NIV chemotype.
