BBKA Statement on recent bee losses in Germany
Published May 30, 2008
Bee Losses:
Members of the BBKA Executive note with concern the recent devastating bee losses in Germany and elsewhere, which appear to be linked with pesticide use. Initial enquiries indicate that the principal problem seems to relate to the application of pesticides to seeds as a dressing. The substances were apparently applied at an unusually high dosage (to protect against Diabrotica - the corn root worm) and were inadequately ‘fixed’ to the seed, resulting in release into the environment during drilling, possibly blowing on to other crops, so contacting with bees. The German authorities have suspended the approvals for eight seed treatment products pending further investigations. The UK authorities are aware of this development and the following statement has been placed on the CSL web-site:
May 2008 - Seed Treatments and Bees
In respect of the current concerns about the threat of seed treatments for maize to bees, the Pesticides Safety Directorate has advised as follows: We are aware of the concerns in some other Member States about the use of certain seed treatments containing clothianidin and imidacloprid. However, we are not aware of any problem in the UK related to any seed treatments and bees. There have not been any incidents reported to the Wildlife Incident Investigation Scheme (WIIS.) to date which could be connected to the use of seed treatments. Given the vigilance of beekeepers it is highly unlikely that had there been any incidents they would have gone unnoticed.
Of the three active substances which are mentioned only imidacloprid is approved for treatment of oilseed rape seed and clothianidin for maize seed. This is the first year in which treatment of maize seed with clothianidin has been approved in the UK. We note that in the incidents in Germany the treatment was being used at a very high rate, 125 g a.s./ha in an attempt to control Diabrotica. In the UK it is approved at a maximum rate of 60 g a.s./ha on maize.
We will, of course, keep a close watch on the situation but currently have no concerns that use of these products according to the conditions of approval will cause a risk to bees in the UK.
The BBKA will continue to monitor developments in this area and will advise its Associations and members as more information becomes available.
This is a statement from the BBKA on bee losses in Germany. I hope that you will find this helpful and reassuring to members. Martin Tovey General Secretary.
