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.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
