Yields could decrease by as much as 50 to 100 percent due to the major reduction in pesticides allowed for crops such as roses, chrysanthemums, cucumbers, Brussels sprouts, spring-sown onions, tulips and ornamental shrubs. This could make Dutch cultivation unviable and even mean that cultivation stops altogether in the Netherlands.
Wageningen UR studied two scenarios that are currently on the table. Firstly the European Parliament’s position after the first reading of the common position of the European Commission and Council of Ministers (the 'EP-cut-off' scenario) and secondly the common position of Commission and Council of Ministers (the 'EC-CMR/ED' scenario).
The studies show that the EP-cut-off scenario will result in yields being reduced by 50 to 100 percent due to the banning of a large number of pesticides for roses, chrysanthemums, cucumbers, Brussels sprouts, spring-sown onions, tulips and ornamental shrubs. This makes cultivation in the Netherlands unviable and will have enormous consequences for the production of and international trade in these crops. Cultivation may even disappear from the Netherlands altogether, which would have a major economic and social impact.
Despite the fact that the number of pesticides that would be banned in the EC-CMR/ED scenario is much lower, this scenario would also have a considerable impact on most of the abovementioned crops.
In the proposal of the Council of Ministers and the European Committee for a new Crop Protection Regulation, the criteria for the approval of pesticides are no longer based on risk alone. Other criteria involved include the intrinsic carcinogenic, mutagenic, reprotoxic (CMR) and hormone disruptive (ED: Endocrine disruption) characteristics of substances. The European Parliament decided in autumn 2007 that more active substances should be banned from the EU.Research
Yield losses for seed potatoes, table potatoes, winter wheat, tomatoes and apples are estimated at 15 to 32 percent. The profit made from cultivating these crops will be significantly reduced, which will put pressure on viability and make it difficult if not impossible to pay fixed costs. In addition, with so many pesticides being banned in this scenario, other problems are likely to emerge as diseases, pests and/or weeds become resistant to the remaining pesticides and harder to control.
Other long-term effects are hampering weed management, a growing nematode population and an increase in diseases and pests that were also affected (side effects) by the former pesticides. The long-term effects of this study were not formulated into exact figures but are also likely to have a significant impact.EC-CMR/ED Scenario
Ornamental shrubs, spring-sown onions, roses and chrysanthemums will be affected by the lack of pesticides to such a degree that cultivation will result in losses or become economically unviable. Fixed costs will become hard or impossible to pay. There will also be yield losses in the cultivation of seed potatoes, table potatoes, sugar beet, Brussels sprouts, cucumbers, tomatoes and apples and these crops will become less economically viable. Only the cultivation of winter wheat will be relatively unaffected despite the fact that several pesticides will be banned for this crop as well.
This scenario may also lead to long-term effects including increased resistance and a growing nematode population.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
