BVL orders the suspension of the approval for seed treatment products

The Federal Office for Consumer Protection and Food Safety yesterday,
May 15th 2008, due to the fact that recent calculations within the
approval procedure have provided new insights, ordered the suspension of the approval with immediate enforcement pursuant to Section 80 Paragraph 2, sentence 1 No. 4 VwGO for the following seed treatment products:

-- Antarc, BVL registration number 4674-00
-- Chinook, BVL registration number 4672-00
-- Cruiser 350 FS, BVL registration number 4914-00
-- Cruiser OSR, BVL registration number 4922-00
-- Elado, BVL registration number 5849-00
-- Faibel, BVL registration number 4704-00
-- Mesurol liquid, BVL registration number 3599-00
-- Poncho, BVL registration number 5272-00

This decision was made after a thorough examination of the current facts in light of the damage to honey bees in the south-western regions of Germany. For the BVL it was necessary to examine whether a relationship exists between the reported poisoning of bees and the planting of seeds treated with plant protection products.

This examination revealed, that the distribution of insecticide-treated
seed with pneumatic drilling equipment constructed in a certain way
resulted in a higher exposure of bees, then the approval process
originally assumed.

New risk assessments, initiated because of the damage to bees and which take this increased exposure into account, make it appear likely, that it can not be ruled out, that the impact of this exposure will lead to
unacceptable effects on bees. In this context, the safety of the user in
the seeding process will be reviewed as well.

Because of these new findings, in order to avoid further damage to the
bees and to definitively clarify the relationship and possible further
impact on the environment we order for precautionary reasons until
further notice a suspension of registration.

Also the regional agencies responsible for advising on the use of plant
protection products have been informed immediately to inform the users accordingly.

Background information on the suspension of authorisation

With the suspension of the licences no imports, no marketing and no
continued application of the plant protection products is permitted.

The same applies to Section 16e para 2 PflSchG also for plant protection products for which a transport certificate with reference to any of the above approvals was granted.

Unexplained Mass Die-Off Hits German Hives

By Andrew Curry

Bees in the German state of Baden-Württemburg are dying by the hundreds of thousands. In some places more than half of hives have perished. Government officials say the causes are unclear -- but beekeepers are blaming new pesticides.

Bees in southern Germany have been dying off in their hundreds of thousands.
In Germany's bucolic Baden-Württemburg region, there is a curious silence this week. All up and down the Rhine river, farm fields usually buzzing with bees are quiet. Beginning late last week, helpless beekeepers could only watch as their hives were hit by an unprecedented die-off. Many say one of Germany's biggest chemical companies is to blame.
In some parts of the region, hundreds of bees per hive have been dying each day. "It's an absolute bee emergency," Manfred Hederer, president of the German Professional Beekeeper's Association, told SPIEGEL ONLINE. "Fifty to 60 percent of the bees have died on average, and some beekeepers have lost all their hives."

The crisis hit its peak last weekend. Beekeepers from Germany's Baden-Württemburg reported hives full of thousands of dead bees. The worst-hit region, according to state officials, was along the upper Rhine river between the towns of Rastatt and Lorrach. The Rhine valley is one of Germany's prime agricultural regions.

Regional officials spent the week testing bees, pollen, honey and plant materials to look for the die-off's causes. The Julius Kühn Institute in Braunschweig, a federal research institute dealing with agricultural issues, set up a special hotline for beekeepers to send in dead bees for analysis.

Blaming the Pesticides

But on Friday, Baden-Württemburg Agriculture Minister Peter Hauk said scientists still weren't sure what was behind the disaster. "As long as the causes are still unclear, we must consider all the possible ways we can reduce the risks for the bees," Hauk said. Hauk encouraged beekeepers to move their hives outside the affected area to prevent further damage.

Meanwhile, Germany's beekeepers were pointing fingers at one of Germany's largest companies, blaming a popular, recently-introduced pesticide called clothianidin for the recent die-off. Produced by Monheim-based Bayer CropScience, a subsidiary of German chemical giant Bayer AG, clothianidin is sold in Europe under the trade name Poncho. It's designed to attack the nervous systems of insects "like nerve gas," says Hederer. The chemical was used last year to fight an outbreak of corn rootworm, and its success against the pest led to a much wider application this spring up and down the Rhine.

Beekeepers across Europe have been struggling to keep their hives alive. A recent die-off in Germany is the latest blow to a beleaguered but vital species.
But clothianidin is not a particularly selective poison. According to the US Environmental Protection Agency's fact sheet on the pesticide, "clothianidin is highly toxic to honey bees." Seeds are treated with the clothianidin in advance or sprayed with it while in the field, and the insecticide can blow onto other crops as well. The chemical is often sprayed on corn fields during the spring planting to create a sort of protective film on cornfields. Beekeepers say it's no coincidence that the bee die-off began at the beginning of May, right when corn planting started. "It's the pesticides' fault, one hundred percent," Baden Beekeeper Association chairman Ekkehard Hülsmann told the Bädische Zeitung newspaper.
The circumstantial evidence is piling up. Beekeepers and agricultural officials in Italy, France and Holland all noticed similar phenomena in their fields when planting began a few weeks ago. French beekeepers recently protested the use of clothianidin in the Alsace region, just across the Rhine from Baden-Württemburg. Hederer said German officials have been ignoring the damage pesticides do to bee populations for years. "The people who work in government agencies are all in the pockets of manufacturers," he said. Beekeepers are fed up, he says: "We've decided that keeping bees is more important than keeping our mouths shut."

The Canary in the Coal Mine

Nonetheless, government officials say the early results aren't conclusive. "The bees that were tested showed a buildup of [clothianidin] … but in such small amounts that the scientists couldn't say it was definitely the cause," the Baden-Württemburg Agriculture Ministry said in a statement on Friday. "The expert commission will continue its urgent investigation." Hauk said the ministry was developing new guidelines for farmers using clothianidin to reduce the amount bees were exposed to.

As intensive agriculture becomes more and more common in Germany, the country's insects are beginning to suffer. Like the proverbial canary in the coal mine, bees are a prime indicator of the environment's health. The consequences could be dire -- bees pollinate 80 percent of German crops, from apples to rapeseed. A total bee collapse could cost German farmers billions of euro.
The latest die-off is hitting a bee population already battered by a particularly long, wet and cold winter. Infestations of bee parasites like the varroa mite have also taken a heavy toll on bees in the past few years. Germany's bees are still in better shape than those in the United States, where the mysterious "Colony Collapse Disorder," or CCD, has devastated the American beekeeping industry. "Bees in the US -- with its huge farms -- get a lot more attention than Germany, with its little fields the size of handkerchiefs," Hederer says. "It's sad, but true: There always has to be a huge catastrophe before people start to use their brains."
