16. Value of tMRL if needed
Not relevant, EU MRL exists
17. Validated analytical method
for monitoring of residues in plants and plant products.
EU method exists
18. Function of the product
Insecticide for seed treatment
19. Type of danger to plant production or ecosystem.
Serious damage caused by cabbage stem flea beetles (Psylliodes
chrysocephala).
Attacks of the cabbage stem flea beetles occur in cycles, which include some years of
moderate attack and some years of heavy attack. In the fall of 2014, many cases of heavy
attack were observed in Denmark and in the fall of 2015, even stronger attacks are expected.
The lack of effective insecticides for seed treatments means that the crop has to be sprayed
with pyrethroids 1-2 times more in comparison to an effective seed treatment procedure. More
frequent spraying increases the resistance development in Psylliodes chrysocephala against
pyrethroids.
Aarhus University has recently discovered the so-called kdr mutation that confirms resistance
to pyrethroids of cabbage stem flea beetles in Denmark. In northern Germany and the UK is
resistance of cabbage stem flea beetles towards pyrethroids a big problem, and there is
virtually failure of control.
In order to delay the development of resistance, dispensation to use more effective
insecticides are required, so the need for spraying can be reduced, and the development of
resistance can thus be delayed. If cabbage stem flea beetles no longer can be controlled, it is a
threat towards rape cultivation because severe attacks, requires re-sowing. Rape is the most
important rotation crop in Denmark, and a very important crop for practicing IPM and
biodiversity.
20. Size and effect of danger
Winter oil seed rape is cultivated on app. 150,000 ha in 2015. It can be very difficult or
impossible to cultivate oil seed rape without effective chemical control of cabbage stem flea
beetles.
Yield loss if there were no resistance against pyrethroids:
It would be necessary to spray one more time with the pyrethroids in average over the years.
The cost of this spraying will be 13
€
for the insecticide + 9.50
€
for the work. Total it would
be 22.50
€
pr. ha.
If we assume there are 150,000 ha, the cost for Danish agriculture will be about 3,350,000
€
pr. year.
Yield loss if there is resistance against pyrethroids:
On average over the years, a 15-20 % decrease in seed yields is expected caused by cabbage
stem flea beetle. On average the yields in Denmark are 3.8 tons pr. ha. The prices have been
0.33
€
pr. kg which results in a loss of value of 28,691,000
€
pr. year in Danish agriculture.

In years with the heaviest attacks, winter oil seed rape will not be cultivated on many farms. It
is estimated that areas with oil seed rape will change to cereals on many farms. On most of
these farms there will be no break crops. Break crops increases yields in the following crop
and decreases attacks of pest and diseases.
21. Absence of any other reasonable means
The only alternative control measure is the use of insecticides belonging to the group of
pyrethroids. Using these kinds of insecticides will increase the risk of developing resistance
in
Psylliodes chrysocephala.
22. Rationale
Risk mitigation measures are prescribed as described in section 23.
23. Mitigation measures
Seed treatment is performed only indoor in professional seed treatment facilities by qualified
personnel.
Labelling of treated seed bags will be done according to EU regulation.
Seed drilling will be performed following best agricultural practices and only by professional
users.
24. Applications in progress
No applications for this use are in progress.
25. Research activities
An EU-project (2013-2014) with the scope of investigating how neonicotinoid seed treatment
products used on rape seed and turnip rape affect bees in EU is ongoing. Preliminary results
do not show any negative effect on vitality or wintering of bee hives.
No alternative products or methods have been found until now.
