17 September 2007 - Five
different groups of products covered by
the pesticide regulation were included in
the 2005 analytical chemical authority control:
1) Herbicides containing diquat dibromide,
florasulam, flupyrsulfuron-methyl, metsulfuron-methyl,
and tribenuron-methyl. 2) Fungicides containing
dithianon and pyraclostrobin. 3) Insecticides
containing esfenvalerate and diflubenzuron.
4) Rodenticides containing bromadiolone.
5) Repellents containing thiram.
All samples were examined for the content
of the respective active ingredients for
the content of OPEO and NPEO except the
rodenticides. Nine samples out of twenty-one
contained bromadiolone which did not comply
with the accepted tolerance limits with
respect to the content of the active ingredient
as specified in Danish Statutory Order on
pesticides. None of the examined samples
contained OPEO, but two of the samples contained
minor concentrations of NPEO. On one product,
the content of active ingredient was declared
only in g/L, but not in % (w/w) as required.

Summary
Described in this report is the analytical
chemical authority control of pesticide
products on the Danish market in 2005. Samples
of selected groups of pesticides have been
collected from the market and analysed to
verify whether the actual contents of the
respective active ingredients in the
products comply with the labelled content.
The tolerance of deviation from the labelled
content of active ingredient is set by the
Danish Statutory Order on pesticides. In
addition to the examination of the content
of active ingredients, all collected samples
except the rodenticides are examined for
the content of octylphenol ethoxylates (OPEO)
and nonylphenol ethoxylates (NPEO). The
industry and the Danish authorities have
agreed on removing these compounds from
all Danish-sold pesticide formulations produced
after June 2000.
Five different groups of products covered
by the pesticide regulation were included
in the 2005 analytical chemical authority
control:
Herbicides containing diquat dibromide,
florasulam, flupyrsulfuron-methyl, metsulfuron-methyl,
and tribenuron-methyl.
Fungicides containing dithianon and pyraclostrobin.
Insecticides containing esfenvalerate and
diflubenzuron.
Rodenticides containing bromadiolone
Repellents containing thiram.
Satisfactory results were found for herbicides
containing diquat dibromide, florasulam,
flupyrsulfuron-methyl, metsulfuron-methyl,
and tribenuron-methyl, for fungicides containing
dithianon and pyraclostrobin, for insecticides
containing esfenvalerate and diflubenzuron
and for repellents containing thiram. Thus,
the analysed samples of these formulations
complied with the accepted tolerance limits
with respect to the content of the active
ingredient as specified in Danish Statutory
Order on pesticides.
Nine out of twenty-one products containing
bromadiolone did not comply with the tolerance
limit for the content of active ingredient.
The content of bromadiolone in eight samples
was too low compared with the declared content,
while the content in one sample was too
high.
None of the examined samples contained
OPEO, but two of the samples contained NPEO.
The concentration of NPEO in the formulations
was approximately 0.01 %.
On one product the content of active ingredient
was only declared in g/L, but not in % (w/w)
as required by the Statutory Order.
